The total power of bands of mobile phone jammer is 40 wattCan beabsorbed by the material loss nomogram derived

Many people do not understand the principle of electromagnetic shielding, do that as long as a metal box, and then ground the box, you can play the role of electromagnetic shielding. Under the guidance of this concept results in a failure. Because, electromagnetic shielding and shield grounding or not does not matter. The real impact of the shielding effectiveness of the shield only two factors: one is the entire surface of the shield conductivity must be continuous, one can not directly penetrate the shield conductor. The transmitter output of cell phone jammer is adjustable. There are many conductive shield discontinuity points, the most important one is the combination of different parts of the shield formed at the non-conducting gap. These non-conductive gap gave rise to the electromagnetic leakage from the container as fluid will leak on the cracks on the same. One way to solve this leakage is to fill the gap at the conductive elastic material, to eliminate non-conductive points. It's like in the fluid container, fill the gap at the rubber for the same reason. This flexible conductive filler material is magnetic gasket.

In many documents will be sealed electromagnetic shield metaphor of the liquid container, it seems that only when a conductive elastic material to leak to the extent of the gap was sealed to prevent leakage of electromagnetic waves. cell phone jammer can nonstop work without any break. In fact, this is incorrect. Because of gaps or holes will leak electromagnetic waves, depending on gaps or holes relative to the size of the wavelength of electromagnetic waves.

An electric field shielding
Shielding mechanism: the electric field sensor as a distributed capacitance between the coupling.
[Design elements]:
a, shield plate to close the protected material as well, and the shield of the ground must be good. . .
b, shield shape of the shielding effectiveness of the level of significant impact. Closed metal box is best, but works hard to do.
c, shield material to a good conductor as well, but the thickness is not required, as long as there is sufficient strength can be a
In short, the electromagnetic shield the electromagnetic wave attenuation is mainly based on the reflection and absorption of electromagnetic waves.

[Loss] absorption of different materials, different material thickness for the absorption of electromagnetic waves is not the same. The total power of bands of mobile phone jammer is 40 wattCan be absorbed by the material loss nomogram derived.
[Return Loss] is divided into three categories: low-impedance magnetic field, high-impedance electric field, plane wave field.
The low impedance and high impedance electric field reflection loss calculated in the same column chart, and metal materials, frequency and distance from the radiation source to the shield.
For a plane wave, wave impedance is a constant, with the distance from the radiation source to the shield has nothing to do, only in the column chart to connect metallic materials and in the frequency of interest can be obtained at this time of the return loss values.The vehicular GPScell phone jammeris with the car adapter.

The power of mobile phone jammer for CDMA is 50W

Indices and technologies of cell phone jammerare on the world’s level
More serious interference range will be further expanded, and even interfere with the base station to a standstill near the district, factories, large-scale units are strong, people will anger quite heavy; by residents and Mobile, China Unicom, Telecom and other operations of the complaint, and local radio management department of the prison to work these issues to bring some negative effects , disrupting the harmonious relations between police and the public. Power of each channel can be adjusted according to the operational environment for cell phone jammer.3) The system is running stable: good times and bad, is not high reliability, fault-prone. In particular, summer and fall, a large number of equipment failures damage, even after the replacement of large equipment are still unable to achieve the desired shielding effect; for people with ongoing maintenance, labor life a waste of money, just like chicken. The poor performance of the prison phone system several shielded main four. The poor performance of the prison phone system shielded a few main reasons.The power of mobile phone jammer for CDMA is 50W.  First, the subjective awareness of mobile shielding system 1) lack of proper shielding the prison system and a comprehensive understanding of the common market between the civilian nature of cell phone jammers difference. The prison system is a set of shielded communication technology, radio transmitter receiver technology transfer, electronic warfare technology, equipment, comprehensive technical and performance indicators for the perfect combination of product, not the general civilian use a large number of mobile phone jammers easy distribution to use. 2) lack of system cost and input-output ratio of the integrated and scientific analysis.This kind ofcell phone jammeris used in places where requires high demands and far distance.  People often make the minimum investment funds to produce the greatest results, however, ignored the basic technology in the product a reasonable investment. As well as procurement can not use a fundamental technical requirements for low-end prison project equipment products, is intrinsically flawed, leaving endless risks for the future. 3) of the sales staff in front of the enterprise market driven by economic interests to exaggerate the strength of corporate and product quality, to make myself do not understand the commitment and can not be achieved, have a problem if in the future, and placed their own good social skills, customer relationships to make up hope the problem the product itself (and even some equipment suppliers knowing the product itself seriously flawed).The jamming area ofcell phone jammercould be adjusted precisely. Second, mobile shielding device itself because 1) At present, many domestic enterprises shielded equipment production and sales, in product development application did not put a lot of manpower, financial resources, without a corresponding increase in key technologies, instead of using the OEM, generic, low-cost, low performance, low-price strategy, selling mass-produced, widely exaggerated marketing campaign depends, in the general civilian market is not critical to achieve a certain profit, while in prison want high standards, high demand, high reliability market segments occupied place, but eventually will shield the prison phone system incalculable loss. .

usually used in an environmental sealing requirements of the occasion. From the structure on the points, plates and strips are two types of hollow and solid material is divided into two. Plates have different thicknesses. Materials: silicone rubber mixed with copper, aluminum, silver, silver-plated copper, silver-plated aluminum, silver-plated glass powder and so on. Response time of a cell phone jammer switching on or off is short. The shielding performance: low-frequency shielding effectiveness of low and high frequency shielding effectiveness when high.

Main advantages / disadvantages: while providing electromagnetic sealing and environmental sealing. Hard, high prices, because the surface is relatively soft, and sometimes can not pierce the surface of the metal oxide layer, resulting in shielding effectiveness is very low. Finger guard: usually used in the contact surface sliding contact situations. Many traits, the material is beryllium copper, but do different surface coating. The police can act more accurately and timely when capturing the suspect through using cell phone jammer. Shielding properties of high-frequency, low-frequency shielding effectiveness is relatively high.

Main advantages / disadvantages: large deformation, high shielding effectiveness, allowing sliding contact (which facilitates removal) / high price. Spiral pad: from beryllium copper or stainless steel rolled into coils, high shielding effectiveness (all electromagnetic shielding effectiveness of the highest sealing gasket). Main advantages / disadvantages: low price, high shielding effectiveness / easily damaged when exposed to excessive compression.There are two types of metal mesh sandwiched between two layers of glass composition, the other is on the glass or transparent plastic film coated with a thin conductive layer composition. The electric carrier wave is the technical core of the wholecell phone jammersystem. The former material has the advantage of shielding effectiveness of high disadvantage is that because the visual discomfort caused by Moire fringes. The latter material just the opposite.

Transparent method of shielding windows features:

Advantages: Simple, display device will produce radiation or sensitivity to external interference can be used.

Disadvantages: poor vision, when the magnetic field inside the device sensitive to radiation or magnetic circuit is not suitable; (transparent shielding material for shielding effectiveness is very low or no magnetic field), when the window is large, the cost is higher.The meeting information security equipments contain mobile phone jammer.



Conductive fabric gaskets: Conductive fabric wrapped on foam rubber core structure, usually rectangular, with adhesive, installation is very convenient. The unique design of an antenna of cell phone jammercan avoid inconvenience of many-antenna blocking. When high-frequency shielding effectiveness is relatively high.Main advantages / disadvantages: low prices, excessive compression is not easily damaged, soft, with some environmental seal / frequent friction can damage the conductive surface.

12 used magnetic sealing gasket Notes

The cover radius of mobile phone jammer is large

Power supply switch of the host cell phone jammer
The largest conductor surface field, the more in-depth internal conductors, the amount of the smaller field. This phenomenon is also known as skin effect.
The cover radius of mobile phone jammer is large.This is because the conductivity of the metal conductor conductivity than air a dozen orders of magnitude larger, while the ferromagnetic material and the air permeability of the difference only a few orders of magnitude, typically about thousands of times, so the static magnetic always some leakage magnetic shielding order to achieve better shielding effect, shielding layers can be used to leak into the cavity where the residual magnetic flux to block out time and time again, so good magnetic shielding effects are generally more cumbersome, but if you want to made absolute "static magnetic vacuum", you can use superconductors Meissner effect. cell phone jammer is an ideal, advanced and reliable product with safety. About a superconductor on the external magnetic field, the body of the magnetic induction B is always zero. Superconductors is completely anti-magnet, with the best static magnetic shielding effect, but is still not widely used for electromagnetic shielding electromagnetic field propagation in conductive media, the field quantities (E and H) the amplitude increases with distance decay exponentially from the energy point of view, the electromagnetic waves in conductive media energy loss when spread, therefore, the amount of the performance of field amplitude decreases. the largest conductor surface field, the more in-depth internal conductors, the amount of the smaller field. cell phone jammer only blocks cell phone signals in the specified area.This phenomenon is also known as skin effects can prevent the use of skin effect high-frequency electromagnetic waves penetrate a good conductor and electromagnetic shielding device made of it than the static, static magnetic shielding more general electromagnetic shielding is to prevent interference, to enhance equipment reliability and effective means to improve product quality. Here is the product performance of cell phone jammer.Reasonable use of electromagnetic shielding, can inhibit the external high-frequency electromagnetic interference, but also as a source of interference to avoid affecting other equipment such as radio, aluminum hood with air-core coil outside, it's free from outside interference time-varying field in order to avoid noise. Audio feeder with a shielded cable is the reason. CRT skin and iron, but also to make the stray electromagnetic field does not affect the scanning electron beam in the metal shield inside the shell components or high-frequency electromagnetic waves generated by the equipment but also through the metal shell and not will not affect the external equipment. electromagnetic shielding material for what it? The screening frequency range of cell phone jammer could be controlled. Good conductor due to electromagnetic wave attenuation in the fast decay to the conductor surface to the surface value of 1 / e (about 36.8%) at the thickness of the skin known as the thickness (and said the penetration depth), indicated by d, electromagnetic shielding, electromagnetic field propagation in conductive media, the field quantities (E and H) the amplitude increases with distance decay exponentially from the energy point of view, the electromagnetic waves in conductive medium when the transmission energy loss, therefore, the amount of the performance of field amplitude decreases.

The blocking range of mobile phone jammer can be adjusted according tothe locations

Figure 2.6 shows the magnetic shielding and the equivalent magnetic circuit diagram
Clearly the magnetic flux is shielded with the shield in space appear shunt.The police can act more accurately and timely when capturing the suspect through using cell phone jammer.
So most of the magnetic flux flows through the shield, reaching less interference field strength of purpose. Since Rm and μ is inversely proportional to the magnetic shield which use steel, iron, permalloy high permeability magnetic material. The above conclusions both for constant magnetic field or low frequency alternating magnetic field is applied. Because low frequencies, eddy current generated by induced current shielding effect has been small.
Which will spread to the other side of the shield greatly reduced space of electromagnetic energy, played a role in shielding. The unique design of an antenna of cell phone jammercan avoid inconvenience of many-antenna blocking. Obviously, the greater the induced current and charge, the resulting reflected field, the stronger the heat loss (absorption loss) the greater the attenuation of the transmitted wave more. Therefore, the electromagnetic shielding conductive material should be used.

Shielding theory is not yet mature in the period, people tend to only use this method of calculation, but with the deepening of theoretical research, there has been applied to different frequency ranges and different calculation methods application object, which should be based on their specific situation to a variety of methods were used.
According to the application of the theory, the method should be mainly applied to the case of plane waves, both the high frequencies.The blocking range of mobile phone jammer can be adjusted according to the locations.

3.2 based on scattering theory calculation of shielding effectiveness.

When the shield structure size smaller than the wave length long, the incident electromagnetic wave (relative to the shield) do Reyleigh scattering, are discussed at this time can be high impedance magnetic field source and a low impedance source shielding.

There is no gap in the leak, the screen effect at high frequencies than low frequencies, the higher the frequency, the larger screen effect.The electric carrier wave is the technical core of the wholecell phone jammersystem.Inclusive type of cable screen effectiveness is also inclusive layer and the metal material and thickness, the better the conductivity, the thickness of the thicker, the higher the efficiency of its screen. It can be seen from the figure, the thickness of 0.6 m of the silver screen effect with heat-shrinkable tube 1.2 m thick nickel-plated heat-shrinkable tube the same.

Medium Setting ofcell phone jammer
If the TCL in the aesthetic point of view coupled with quality and cost control is good, If this continues, TCL Mobile is promising. Unfortunately, when in 2004, TCL made a major decision, this decision has affected the development of TCL cell phones, as the impact is good or bad, still uncompromising. October 9, 2004, as French President Jacques Chirac's visit to China signed 20 cooperation agreements in an economic, TCL and Alcatel signed a joint venture company set up a formal contract cell phone. The medium setting ofcell phone jammeris one of the most common setting selection ofcell phone jammer.
"This merger will enable TCL share of global cell phone market share rankings, from No. 15 now up to No. 7, which is the first domestic cell phone enterprises into the global cell phone industry's top 10." In the opening ceremony of the day on, TCL chairman Li Dongsheng, unashamedly and president, said. His lung power, authority from the global investment bank Morgan Stanley as a joint venture of TCL and Alcatel issued a research report. The study reported that after the establishment of the TAMP, its parent company TCL Communication (including TAMP and TCL Mobile) cell phone-year sales will reach 20 million, became the first Chinese mobile phone jammer sales, the seventh of the global cell phone sales cell phone production the manufacturer. The worker can perform the several settings ofcell phone jammerexpertly.
However, only seven months hand, due to poor integration with the huge losses, so that TCL and Alcatel's cell phone "marriage" ushered in a split moment. Mid-2005 financial statements show losses of 1.17 billion cell phone business, while operating on the high cost of overseas markets, intense competition in domestic market sales have been declining from such bad information. November 18, 2005 this day, Wan Jianming, "illness" to resign from the TCL. This is outside of TCL Mobile doubt the most high international project period. Such as Nokia and Motorola significantly reduced prices, squeezing domestic brands survive, domestic cell phone manufacturers have to lower the cost of cleaning up inventory. The operator of cell phone jammer is showing the medium setting ofcell phone jammer.
On the other hand, has a significant impact on the cost advantage of the local black market cell phones, accounted for no less than 20% of domestic low-end cell phone market, coupled with domestic manufacturers in the market blowout era "human wave tactics" and "machine sea tactics." difficult under high operating expenses and inventory, including TCL Mobile, including making a number of manufacturers across the board losses. Of course, Mr. Li believes that it is not acquisition of Alcatel, the loss may be more, this problem is not easy to say. I remember acquisition of Alcatel TCL Mobile Communication business, Mr. Li vowed to release rhetoric: "My personal credit guarantee, 18 months, the company will be profitable." 18 months since then, the acquisition of Alcatel not only did not TCL to bring the slightest opportunity. The medium setting ofcell phone jammerhas been saved.
And make it difficult for the cell phone business losses of $ 100 million per month, the market share of domestic cell phone is dropped out of the first three, Wan Jianming finally had to sadly leave. In all the voices of doubt, TCL Communication through a whole year of silence, this year the industry as "shock" of the year, Li Dongsheng are called "the worst year." Fortunately, in Li Dongsheng year commitment when the expiration of 18 months, TCL cell phones came Herald, 2006, TCL cell phones into the black. The worker is recording the parameter ofcell phone jammerwhen it is of the medium setting.

To low-end WCDMA handsets has generated demand for a "3", for example, in January this year, opened in the UK 3UK prepaid services, basic post-paid voice tariffs for users with exactly the same charges, but not to include video telephony and other data services bundled. Although the tariff is very competitive (see Table 4), but the lack of low-cost WCDMA handsets, and the use of current high-end WCDMA handset subsidies for prepaid users but also impractical, so the pre-paid business really have to absorb "3" back net post-paid users, while in competition with other operators 2G market in the process of completely losing the battle. The working status of cell phone jammer can be indicated by the indication light.
Similarly, after the issuance of 3G licenses in China, except when the 2G market is already saturated, or low-cost WCDMA handsets will have greater demand. Compared with developed countries, the domestic development of 3G has its own particularity. Has issued 3G licenses in the country, mobile phone penetration rate has reached a higher level, even low penetration rates in New Zealand, Canada and Poland, the end of 2003 mobile phone penetration rate in excess of 40% in the voice business , the mobile voice market in many countries there have been signs of saturation. So for these countries, 3G industry development strategy is prosperity mobile data services, rather than the development and popularization of the 2G market. The mobile phone jammer system has won much praise.
In China, the end of 2003 mobile phone penetration rate of 20.92%, there is still a large-scale expansion of space; in the voice business, the current demand for mobile voice satisfaction just to meet the "subsistence", there is a large away from the saturated the distance. 3G licenses are expected, the domestic 2G market is still considerable room for development. Thus, the domestic 3G mobile data services in addition to promoting development, but also need to bear some of the popular 2G market mission. In addition, from a technical nature to see not only WCDMA also offers the ability to move data, field tests have shown that: in the other conditions being equal, WCDMA voice quality to be slightly better than GSM, WCDMA is actually a very good voice service bearer technology. Cell phone and cell phone jammerhave the close relationship.
Domestic WCDMA license issuance, the original GSM operators and new operators to the specific needs of WCDMA will be significantly different. For the domestic original GSM operators, as 2G market will continue to meet the 2G/2.5G networks, WCDMA mobile data networks mainly to meet the load requirements, which with Vodafone and T-Mobile, is the same. But by entering the domestic mobile phone market WCDMA emerging carriers, due to lack of 2G networks, the demand for 2G, these operators will need to function in the WCDMA network by a simplified low-cost WCDMA handsets and 2G/2.5G operators launched the original competition, low-cost WCDMA handsets will be the operator on the market in 2G key to success. Just from the phone cost. The cell phone in the specific range will be shielded due to cell phone jammer.
WCDMA phone features the same cost of the phone with 2.5G main difference in the core chip set, R & D and manufacture of cost-sharing, patent fees, three parts, with the popularity of single-mode program expansion and WCDMA mobile phone production, these two types of mobile phones cost difference will be shrinking. Combined with the history of mobile phone development, taking into account the complexity of 3G services, mobile technology challenges, market size constraints and other factors, it should be said: At present, commercial WCDMA handsets for WCDMA bottleneck effect produced by a certain necessity and objectivity. With the breakthrough in mobile phone technology, WCDMA business to accelerate the process, single-mode program to further spread, etc., is expected before the end of this year, the bottleneck link of WCDMA handsets will likely be significantly improved the state. cell phone jammerof high quality will gain more and more customers.

CDMA (Code-Division Multiple Access, Code Division Multiple Access), which is a branch of digital technology - spread spectrum communication technology to develop a new and sophisticated wireless communications technology. With the use of time-division Multiple Access (TDMA, Time Division Multiple Access) and GSM different, CDMA does not assign to each caller a certain frequency, but to use every channel can provide full spectrum. CDMA cell phone to use for each group of quasi-random number sequence encoding. Workshop management ofcell phone jammer plays an important role in manufacturingcell phone jammer.
CDMA technology has undergone several stages of standardization. IS-95 series of standards is the first release cdmaONE standard, widely used around the world truly the first CDMA standard is IS-95A, the standard supports 8K encoding voice services. Were subsequently published in the 13K standard voice encoder TSB74 support the 1.9GHz CDMA PCS system STD-008 standards, including 13K encoded voice quality of service has been very close to the wired telecell phone voice quality. With the demand for mobile data services growth in February 1998, Qualcomm announced the IS-95B standard for CDMA-based platform. CDMA IS-95B provides system performance, and increase the user's mobile communication device data traffic, providing 64kbps data service support. The specific power supply is not needed for the detector ofcell phone jammerintelligent system.
CDMA technology standardization, and promote this technology in the world-wide application. Currently in the United States, South Korea, Japan and other countries, CDMA technology has been a large-scale applications. In some European countries, some operators have built a CDMA network. Future global CDMA market, the Chinese mainland's growth potential. PHS (Personal Handy-cell phone System, low-power cell phones), in the domestic nickname "PHS." Earlier by the Japanese in accordance with national conditions (a large majority of local population density and mobility of the population of small features) developed, and in 1996 the market. The system's main feature is the use of FDD / TDD multiple access methods, base and mobile transmit power is very low, the base station is only 500 mW transmit power, the cell phone is only 10 mW transmit power, the transmission power is small, so small informed the standby time and talk time is far superior to the current GSM and CDMA cell phones. Maintenance of adapter of cell phone jammer is very important.
A charge may be 5-8 hours of talk time or 720 hours standby; because the radius of the small frequency reuse, where the unit area can provide more channels and accommodate more users, but also has resulted in every 200-500 m on need to build a base station, the number of sites used by many high-speed mobile wireless channel environment will cause frequent switching, resulting in dropped calls and call quality decline, to achieve greater cost of roaming, network maintenance costs while also expanding rapidly with network size growth. Third generation mobile communication system in the international community collectively referred to as IMT-2000, referred to as 3G, the International Telecommunication Union (ITU) in 1985 proposed work in the 2000MHz band, expected around 2000, the commercial system. At that time the future of land mobile communication system called (FPLMTS), 1996, officially changed its name to IMT-2000. The warehouse needs more room to accommodate more mobile phone jammer.
With the first generation analog mobile communications (such as TACS and AMPS) and second-generation digital mobile communication systems (such as GSM and CDMA, etc.) compared to the third generation of the most important feature is to provide mobile multimedia services, the design goal is to provide greater than the second-generation system system capacity, and better communication quality, and to be able to better achieve global scale and to provide users with seamless roaming, including voice, data and multimedia, including a variety of business, while also consider the second-generation system with the existing good compatibility. Thecell phone jammersystem has the real-time inquiry function ofcell phone jammer.

The company only takes responsibility of changing a new mobile phonejammer or repairingcell phone jammer

For the transformation from 2G operators from the WCDMA operators, 3G services is undoubtedly a greater demand for mobile data users, and users can only use 2G demand existing 2G network to meet, there is no need to use the WCDMA network to meet this kinds of needs. Therefore, for such operators, WCDMA mobile positioning support all business functions will come out ahead. However, direct access through the 3G market, and the lack of sharing policies of the emerging mobile network operators, WCDMA specific location will have a significant difference: These WCDMA network operators not only to greater demand for mobile data services to users, but also to consider the market demand for the existing 2G. The company only takes responsibility of changing a new mobile phone jammer or repairingcell phone jammer.
Therefore, only low-cost business functions 2G WCDMA handsets will become of these operators with existing 2G operators to compete for the 2G market, the key. Only these operators due to the current "3" subsidiaries in six countries, and its influence on the mobile phone industry is still limited, so the demand for low-end WCDMA handsets are often easily overlooked by the industry. The customer can choose the working band of cell phone jammer according to the situation.

And standards in accordance with the timetable submitted to the ITU's screening process, finalized in May 2000, three kinds of major 3G technologies: GSM evolution made by the IMT-2000 CDMA-DS (IMT-2000 direct spread spectrum CDMA), namely WCDMA, it 5M in a wide frequency band spread spectrum signal directly; made by the evolution of CDMA IMT-2000 CDMA-MC (IMT-2000 Multi-Carrier CDMA), that is CDMA2000, which is the technology the United States by a or more of 1.25M of narrow-band direct spread spectrum system consisting of a broadband system. The lower price can be provided forcell phone jammerif the order is large enough.
IMT-2000 CDMA TDD (IMT-2000 time division duplex CDMA): including China's TD-SCDMA (also known as the low chip rate TDD, LCR TDD) and HCR TDD. Throughout all the name brand cell phone, cell phone abroad can be found are relatively standardized naming, cell phone number and name of each letter has a special meaning - they not only represent a model more representative of the manufacturers of this type positioning and strategy. But with the increasingly competitive cell phone market, each manufacturer's new machine introduced more frequent frequency, leading to many manufacturers is not the original numbering system has been used. As many parts of the cell phone number from the 7 l 8-bit, as the number of manufacturers are changing the rules. The expert is researching the defect ofcell phone jammer.
We are just a few major brands of cell phone manufacturers to make a superficial type of research and discussion. Various Nokia cell phone models, market positioning is also very complex, depending on the model of different prefix, generally divided into nine series: 1: low-end series; 2: low-end entry-level cell phone series; 3: really my personality series; 5: Sports dynamic series; 6: Business Elite series; 7: Fashion Pioneer Series; 8: distinguished and elegant series; 9: Personal Assistant series; currently 4 series has not developed a corresponding model, may be left for future research and development of a Nokia series. For these series we have discussed in detail about it: 1 series. At present, only three models, the 1 Series are: 1100,1108,1610. A series full of color tone ring configuration, and low-end series; 2 series. 2 series is the entry-level handsets low-end series. In 2004 Nokia released two new models: 2600 and 2650, are low-end machine. Thecell phone jammerfactory has improved the technology to reduce the rework rate ofcell phone jammer.
3 series. 3 series is really my personality series. This series mainly for the younger generation. This series is characterized by: the cost is generally low, the overall configuration in a low-end Nokia standards. To save costs, a more general form of materials, plastic sense. It should be noted that the 3 Series in 2002 just before the low-end series of one, it has a classic monochrome 3210,3310 and so on. From 02 onwards, on towards the trendy youth market transformation. Starting from 3530, this trend has emerged. To today's 3100,3220 3 series is essentially fixed. In addition, the lack of a small number of high-end 3 series models, 3650,3660 and the new release of 3230 that several smart cell phones. In fact, smart cell phones mainly in the 6 Series and 7 Series, but the two series are more restrained and subtle appearance. The 3 series smartcell phones offer a bold show the personality profile of the stage, 3650 is such a typical topic for. The preventive actions of cell phone jammer and the corrective actions of mobile phone jammer will be performed.
5 series. 5 series is sports activity series. It was also said to feature cell phones series. 5 in the series model, though small, but the leisurely unique personality, both special features. 5110 5 Series is the first case, it is in the first paragraph may be shedding the Nokia cell phone, that's probably very little in the model has this feature. Later in 5510, classical music cell phone, there are a large player can play the sound file to cell phone to listen to music as possible. 5210 with three anti-feature, as it adds movement in the air. 5100 is an upgraded version of 5210, three anti-keeping functions at the same time with the more advanced man-machine interface of the S40 and S40 series of practical features, the Nokia 2003 is a very special model, until now the market is also useful. The test report ofcell phone jammercontains a lot of information.

Purpose Introduction of mobile phone jammer

The cell phone jammer can form an electromagnetic protection field around you to prevent the cell phone leaking and eliminate the noise pollution caused by the cell phone. The cell phone jammer will provide a safe and quiet space for you, which is your reliable and loyal bodyguard.

Purpose Introduction of mobile phone jammer

As the communication technology is rapidly developing in the information age, the mobile phone has become the important tool which is indispensable in people’s daily work and life. However, the wide use of the mobile phone will cause some problems which can not be neglected. Therefore, the cell phone jammer becomes more and more popular.

1.1 It becomes a new leaking channel and threatens the confidential information safety. So, the cell phone jammer is needed to ensure the information safety. As the scientific technology develops, location tracking and supervising of the mobile phone have become the most important detecting means and information resource for almost all countries in the world. Therefore, whenever you carry the mobile phone together with you in the leak location and it is in the standby status, the leaking will be caused no matter whether the mobile phone is used or not, which will do great harm to yourself, to the unit and even the party and nation

From a technical perspective, the advantages of single-mode solutions in the following areas. a. Effective avoid switching between multiple systems. Current dual-mode WCDMA handsets from WCDMA 2G/2.5G network switch to certain problems still exist, and because of their own reasons 2G/2.5G networks will not be able to switch back to the WCDMA network; single-mode phone because they do not support this feature, but to avoid the this problem. b. due to the reduced single-mode WCDMA handsets and GSM / GPRS-related unit of work, complexity, lower than the dual-mode phones, less power consumption, the volume is also an advantage. The cell phone jammer system used for the prison has the higher requirement.
The cost advantages of single-mode phones are: As the complexity of single-mode solution to reduce, in the development, design costs and development cycle than the dual program has a comparative advantage. From the network operator perspective, because the program does not support single-mode GSM / GPRS functionality, need to address interoperability, IOT and other issues but fewer, shorter time to prepare the network business. For existing GSM and TDMA operators, attractive dual-mode solutions have been reduced. Because of the high initial investment and development needs of a certain process of network size, the existing GSM and TDMA operators have hope that dual-mode phone, island-style construction of WCDMA networks and the use of existing 2G networks for voice full coverage in order to take full advantage of the original have the resources, but the years of technology and business practices that, WCDMA and switch between 2G itself against the mobile telephone service should be to minimize the switching principle, not only has a serious impact on WCDMA commercial process. cell phone jammercan work continuously for a long time.
And after consuming a lot of resources on technology there are still many problems, the use of a big gap between expected results and objectives. Continued to decline in equipment costs, the introduction of the European network sharing policies, comprehensive background in Western Europe, some of the land area covered by the smaller countries to achieve full cost of the assessment year as far from amazing, so since 2003, a growing number of 2G operators considered for single-mode strategy. In June 2003, DoCoMo has launched so far the only PDC / WCDMA dual-mode phone, but because of the difficulty of high-technology development, the result is not satisfactory and the use of the FOMA network has been basically achieved full coverage, DoCoMo has completely abandoned the PDC for the Japanese domestic market / WCDMA dual-mode solution. Overall, the single-mode handsets due to technical, cost and network operators on the comparative advantages will be more widely recognized and faster development. The working site of mobile phone jammer contains the military place.

The mobile phone jammer is needed to ensure the security

Training, After Service and Technical Support of Cell Phone Jammer

1 Training of the cell phone jammer

1.1 Training purpose of the cell phone jammer

The training can enable the user to comprehensively know the intelligent management system of school cell phone jammer, understand the daily maintenance, handle the general problem, eliminate malfunction of the system caused by the inappropriate use or operation and reduce the sudden fault.

When site environment requires a more accurate shielding or there exists the area where the shielding is not needed around the shielded area, the directional antenna of cell phone jammer is recommended.

The directional antenna of cell phone jammer can transmit the shielding signal centrally to a specific area. The area where the directional antenna points will be the area where the shielding signal can be transmitted farthest. A small part of the area at sides of the directional antenna and at back of it will still be covered by the shielding signal

Cell phone jammer has little impact on the area beyond the examinationroom

cell phone jammeris manufactured applying the advanced foreign technology
6.2 The shielding effectiveness of shielded cable
6.2.1 shielding parameters on the performance of the cable shield
Shielded cable transfer impedance and shielding effectiveness of shielding by the type of termination methods, material properties, and many other factors, the following will be used Xidian University compiled simulation software to analyze these factors.cell phone jammer has little impact on the area beyond the examination room.
6.2.1.1 Single shielded cable
Braided shielded cable is divided into single, inclusive of two forms, affect the performance of braided cable shielding density parameters are woven, knit and woven wire horn wire diameter, material, etc., affect the performance of the cable shield inclusive parameters shield thickness, material, etc. .
6.2.2.1.1 braid shielded cable
mobile phone jammer applies the special advanced technology according to requirements of the market. Figure 6.6 shows the same density woven, braided angle of three different cable screen effectiveness comparison can be seen from the figure, when low-frequency electric
Cable screen larger effect, with increased frequency, approximately the same value, which was mainly due to low screen shielding effect depends on the DC resistance. The gap at high frequencies because the increasing influence of leakage, resulting in screen efficiency dramatically. It also can be seen, the greater the braided angle (see Figure 6.6), the higher the screen effect. Depending on the hole coupling theory, the hole leakage rate depends on the polarization of the hole, (6.1) gives the hole polarizability expression:
Figure 6.7 shows the braided angle weave density of the same four different cable screen effectiveness comparison can be seen from the figure, weaving density can improve the screen efficiency, but the density is too high will cause the cable is very hard to change their mechanical properties poorly, so the density must be controlled within a certain range. People can enjoy fastness and convenience brought by high technology equipments includingcell phone jammer. As mentioned above, the hole leakage from the hole density of the polarization factor and decided, in the braided angle the same situation, different power densities
The polarization factor of the same cable, thus the leakage depends only on the size of the hole. 40%, 68%, 83% of three densities, for example, (93% density is too high,
Flexibility is poor, should not be used) s3 / 2 were 39 × 10-9,1.9 × 10-9,3.1 × 10-10, the first two times the difference of 21.41, the latter two the difference is only 6.12 times. The maintenance can prolong the useful time of cell phone jammer.Obviously, as opposed to 40% density, 68% of the density can be greatly improved screen efficiency, and high densities, increase the role of screen effect is not obvious.
6.2.2.1.2 inclusive type of shielded cable
Figure 6.8 shows the silver, nickel, the thickness of the cable screen effectiveness of four different compared with the braided cable Instead, inclusive cable from the

Character of this composite structure has the following form: font + temporary shape, such as: Samsung Series mobile N628/A188/A388/A408 / T408/T508, etc., etc. Motorola V70. Samsung N628 composite font, font + chip shape, such as: Motorola V988, V60, etc. Font + temporary + chip-based composite structure becomes more widespread, but many programs and program design imperfections often prone to various failures, weak technological base for the domestic software models, the use of this combinations are likely to lead to software failure, you readers should be careful in the service. The mobile phone jammer system contains the detector.
More detailed description of a variety of logic chips, the following brief on the specific identification method of the common chip. To fully understand the use of an integrated circuit, functional, basic parameters, it must know the type and origin of the integrated circuit. Integrated circuit chips are usually printed on the front of their model or mark, which according to type of prefix or logo will be able to know what it is that the initial production plant or the company's integrated circuit products, according to its figures can know is what kind of circuit functions. General models of IC products for the company code prefix, such as: AM-AMD company, AT-ATMEL Corporation, MC-Motorola, X-XICOR companies. Special such as Intel, the prefix letter on behalf of the production plant integrated circuits omitted, in general, will usually own the factory or company name trademark printed up. The detector ofcell phone jammersystem can detect the signal.
Number of products in the middle of the same model is generally interchangeable. Usually used (not strictly) the title:: 74XX, 74HCXX, 54XX, 40XX, 45XX, 28FXXX, 29LVXXX. If the circuit components, more stringent requirements, it is necessary for the analysis of data provided by the manufacturer to make a decision. For example, AN5620, AN prefix description is Panasonic bipolar integrated circuits, the number "5620" before the two main features distinguish the circuitry, "56" TV with the integrated circuit is described, and 70-76 are stereo uses, 30 39 is a VCR with the circuit. For details, please refer to the integrated circuit factory produced model name. And long to see 28Intel28 cell phone repair and AMD29LVXXX two chips, for example. The detector ofcell phone jammersystem will work with the cell phone jammer.
I / O interfaces (I / O Intterface) input / output interface commonly used I / O interface that, I is the input interface, the English abbreviation of IN. O is the output interface, is shorthand for the English OUT. Input / output interface circuit is a CPU and an external circuit, the connection between the device channel and the control circuit. Due to external circuits, equipment, level of point size, data format, speed, work, etc. are not uniform, under normal circumstances is not compatible with the CPU (that is not directly connected with the CPU), these external circuits and equipment only through input / output interface of the bridge, in order to transfer information between each other, exchange and make the CPU and the external circuit, coordination between devices. The detector ofcell phone jammersystem will indicate where the signal is.
Since I / O components in the structure and working principle and the CPU is very different, they have their own separate clock, independent of the timing control and status flags. CPU is a high-speed components, and I / O components operating at different speeds, so the difference between them is generally able to achieve several orders of magnitude, while the CPU and peripheral I / O data exchange components must introduce the corresponding logic components, to solve two synchronization and coordination between, according to the format conversion. The detector ofcell phone jammersystem is of the high quality and low price.

As storage technology advance

Technical Program ofcell phone jammer System
Cell phone manufacturers This is to protect their own property does not receive illegal copying. Many service workers also tried to use a normal cell phone to remove the font, the data read out and write a new font, and install back to another cell phone, even if it is a cell phone with the above, can not normally use, such as Siemens is to show two lines of English. A detailed technical program of cell phone jammer system is needed.
No, but is encapsulated in the CPU or the font in it. Such as the common 21118 with 1M within the CPUPMB6850 temporary, increase its capacity with a temporary 62127 V998 as a single size. The T190 comes with the CPU 2M temporary, and its "no scratch" also understand the reasons. Of course, the temporary lack of space or damage caused by such crashes will not boot and other faults. Some of the older models before them, CPU, Flashrom \ EEPROM \ SRAM and other chips are independent repair to see the plate know which is the CPU, which is the font, chip, such as Nokia 5510/6110/7110 / 8810/3210, Samsung S600/800/2200 other models. The expert group has approved the technical program ofcell phone jammersystem. MCU clock system is an important system, the microcontroller's job is step by step, arranged in chronological order according to certain rules of timing is controlled by the clock system. Clock signal microcontroller to execute instructions to do the operation when lined up in chronological order, and not an operational requirement for a good fixed time, so we should make a chip at a time only movement, to achieve the orderly work of the circuit. And it works and the speed and the status of the majority of cell phone in the boot files need to be addressed more by the time required is short, the clock more for 13MHz, while in standby or hibernation when 32.768kHz enough. This is somewhat similar to the computer CPU clock speed, which is why when the mobile phone jammer is switched 13MHz frequency offset that does not matter, as long as there is sufficient amplitude can send data on the line, and if unable to calibrate the network and base station when one of the reasons. Thecell phone jammersystem is well accepted in the market for its high availability.

As storage technology advances, more and more integrated devices and cell phones in the small, therefore the new cell phones are now more complex structure of the chip using simple point that is integrated into a single chip or package into another piece of chip, Looking now the newer cell phones, many of them are temporary and the chip has been "does not exist" because they were closed near the CPU or some character, the above mentioned Motorola T190's CPU with 2M on a temporary Nokia 8310 with 8M of CPU temp. Character of the function is more and more powerful, a lot of chip or temporary character be integrated to form a composite structure of the font, font feature of this compound is very powerful, widely used in new cell phone. The technical program ofcell phone jammersystem is specially made for the prison.

The operation condition of cell phone jammer is an important part ofthe log

the iPhone to carriers (China Unicom) is in a vulnerable position, the business of the iPhone development there are substantial limitations, and are vulnerable to the constraints of the operators. Summary of the environmental analysis of corporate strategy and SWOT analysis. Through the above analysis, we conclude that the iPhone through its own advantages, combined with a good external strategic environment, be that the Chinese market to achieve better results. The same time, we can find in the Chinese market, the iPhone advantages and disadvantages are very obvious Generally speaking, the advantages outweigh the lack of, but if we do not own shortcomings in a timely manner to the processing and strategic adjustment, is likely to have a iPhone in China The development of the market caused a fatal blow. It is the fault status of every cell phone shielding position of  cell phone jammer .
From the success of the iPhone we can get the following revelations: First, technological progress and needs of complex continue to promote the innovation revolution, at the same time it also brings the integration of products and industries. Difficult for us to mobile phone communications products, its body combines the advanced technology in home appliances, communications, computer, entertainment and other industries. Apple's differentiated portfolio to cater to further promote this integration. Standing in front of the market to guide the market is the key to the success of Apple. Second, tactical, Apple competitors from two perspectives pull distance. Apple continued technological innovation always is an industry leader, Apple's differentiated portfolio imitation obstacles to block the opponent in the back. The fault status of  cell phone jammer  has been recorded in the log.
Maintained its leading position, to fight for their own time to obtain the value and the next round of competition. Third, innovation and the opponent's time difference, for Apple to win a culture of consumer groups, the opportunity to consolidate its brand influence. Consumer groups accepted the spirit of the Apple brand to become an organic component of the Apple brand, promote and protect Apple's innovation and competition. Apple is no longer a company, it has become a demand. Finally, Apple in the Chinese market, the mode of operation and market strategies to reposition and grasp, so its better development. Thesis: Analysis of the marketing channels of the iPhone in the market. Repair of  cell phone jammer  should be immediately applied at this position.
Steve Jobs (Steve Jobs), president and CEO of Apple Computer, Inc., announced that the iPhone officially released some quips: "We re-invent the phone ......". This indicates that the mobile phone revolution has entered a new era, mobile phones became more powerful. The iPhone will completely refresh the concept of mobile phones and other mobile phones can not match the power. September 25, 2010, the iPhone is officially available for sale in Mainland China. Really led to an "Apple's hot" trend, the paper used on Apple and the mobile phone industry market conditions, analysis of Apple's new product the iPhone target market selection and product positioning, and pointed out that a major competitive advantage for Apple and the iPhone. The light can indicate the position of  cell phone jammers   .

There exists the changed electric field or moved electric charge ofcell phone jammer

This caused the market the way of hunger, the use of but reached a pinnacle. Agree with my value, my customers, please follow me. Apple's marketing has been to rally the spirit and values and to guide consumers, beyond the pure product level, this is the pursuit of the highest level of brand marketing. A real difference, others to educate consumers, Steve Jobs is to attract, "take the bait. Word of mouth marketing - the mobile phone communication tool into the era toys. Marketing must be amused, so that it can spontaneous and voluntary happy to participate. Entertain the public network microblogging normalizing the moment, the iPhone cell phone acts as a stylish tool. Entrepreneurs, star of the high popularity of the microblogging with the iPhone fat amused information. So the magnetic field will be formed around the host and antenna of cell phone jammer .
The information will be marked at the bottom of this information from iPhone users. This allows more play microblogging want to have the logo. Is there any other mobile phone brands like a star chase? I am afraid that only Apple. "Apple fans" are chasing Apple's products, often selflessly around the people to show off their love machine and personally demonstrates the exchange of experience, to show off the love machine, personalized accessories, and even go to holding an apple notebook. Even Sony, Dell, Nokia ringing-in-class brands, the enthusiasm of its users also can not be compared with the "Apple fans" crazy. Extreme humanity marketing. Apple is why it is so fascinating? In the face of Apple, all the so-called star product will be eclipsed. The strong magnetic field is from the host and antenna of cell phone jammer .
Apple released a new product, can make the world of Apple "fans" for their products and crazy, the media is scrambling to the widely reported, but also affect the stock market, affecting the industry, which is Apple's humanity marketing. Jobs' philosophy is to "do the right thing", the correct, not a technical, not design, not aesthetics, but "human nature". In fact, at the time, Jobs in the eyes of "the right thing" are anti-traditional, non-mainstream. Infrared sensing such as the iPhone, the phone automatically turns off the screen. When you call the iPhone close to the face, the iPhone will automatically turn off the power saving of the screen. This is not how clever technology. The magnetic field will reduce the output voltage of the power adapter of cell phone jammer .
Why do many of the advertised people-oriented company is not found. Nokia also has a distinctive brand personality that is cost-effective, strong and durable, but this character can only be classified as physical properties. Apple is not so much to sell the product as it is selling human nature, the recruitment consumer product, "like-minded" by focusing. Jobs 1994 Macintosh was born 10 years there is a true confession, as he understood the "humanity" ultimate rule: "Only in-depth core of the problem in order to understand its complexity, but also to identify the fundamental solution. Most people do this step usually will stop, but the truly remarkable people will continue to explore. It is the output voltage of the power adapter of   cell phone jammers .

Cell phone jammer is searched and recorded into the log

Apple did not complete the IPhone In addition to a detailed description of the basic technological innovation, features, resulting in a lot of impatient consumers by phone, e-mail with relevant government departments, media contacts, asking for information. This resulted in the rising popularity of the iPhone. This spread has achieved better results than simply published in the media advertising. Apple is using the channel network media, to disclose information, and then the video ads to appear. These are young people access to information and willing to acquire the channel, and once again confirms Apple's young people as the primary audience of the conclusion. Part 8: Summary. The entire marketing process of the Apple iPhone mobile phone is undoubtedly very successful.  cell phone jammer  is kept in the management department.
Steve Jobs with the least money to manufacture continuous and successful topic. These have fueled the sales of the Apple iPhone. Currently, the iPhone being only in the United States, but a major monopoly of the iPhone are basically sold out. According to the research company's survey, the iPhone is expensive, but 85% of young people are familiar with its performance, of which 1/4 are willing to buy. iPhone marketing positioning is very successful, to seize a young person's psychological, but also taking into account the other main force in the communications market - business people. Of course, Apple is a business, product promotion, marketing does not exist naturally on the issue of public interest and social responsibility. The total position of  cell phone jammer  should be counted.
Apple vs. Nokia: tactical defeat strategy. Core Tip: Many companies tend to focus on strategic issues in the development process. And consumers are closely related to tactical problems due to look pediatrics deprived of the attention they deserve. Nokia's market position is steadily decline. In July of this year, Nokia announced its second-quarter operating earnings, net profit of 227 million euros, compared with net profit of 380 million euros in the same period in 2009, a decrease of 40%. In terms of market share, according to the statistical report of the IT data research firm Gartner, Nokia Symbian smart phone market share has grown from 73 percent of the 2006 ruling of the, down to the current 34 percent average annual decline of 10%. cell phone jammer  should be then turned on and operated as a whole.
The source of the Nokia recession is Apple. Apple's iPhone accounted for only less than 15% of the global smart phone market share, but the iPhone set off a wave of mobile phone innovation and allows the Nokia has been hit hard. Usually to analyze the reason for the success of Apple, that Apple first in the strategy recognize the importance of the mobile Internet and the role of mobile applications; failure to Nokia, naturally due to the short-sighted strategy. Can be the opposite. Nokia is almost the earliest emphasis on Internet applications, mobile phone manufacturers, and even earlier than Apple. The end of 2006, I had the Nokia headquarters in Helsinki, Finland, to visit and interview.  cell phone jammers   has the transformer network.

Here will describe some tips concerning about the wall hanginginstallation of cell phone jammer

With the rapid development of China's 3G network. The phone on the mobile Internet will become increasingly rich. Internet video, data access, listening to music, and even mobile e-commerce. Almost all the PC's Internet applications, can be more or less ported to mobile phones, and open up a new world in the application on the mobile terminal. For students who love learning, smart phones, is a major reform of learning. When someone carrying a heavy school bags to the library to start the day learning for people who have smart phones simply do not need to be too much trouble. Pick up your phone, plus a headset. The working instruction explains the wall hanging installation of  cell phone jammer .
You can go to any one you feel most comfortable, lake, grassland, shelters, playground, etc.. What are the factors of light, you can be ignored. Because you can put in your phone you need to use e-books, learning materials, listening materials. The way of study and work, it is inevitable and students out to relax. With what? MP3, digital cameras, etc., these are all indispensable. However, for you have a smart phone, these and redundant word program on the equal sign. Because these things are smart phones the most basic functions. Use the time to just come up with mobile phones, gently press, if you are in the mood, you can immediately modify photos, and upload it to network with friends. Where the concealed wire of the strong electricity is pre-mounted in the wall where  cell phone jammer will be mounted.
The reform of the smart phone has been or will our lives are endless, because the smart phone has an open systems platform. So theoretically, if you prefer, you can even write your own program, installed on the phone, in order to achieve the functionality you want to achieve. You could almost say, for smart phones, only the functions you can not think, no he can not function. Of course, due to the factors of technological development, the smart phone in the various functions to achieve the effect is only passable, for example, the limit of the CPU production process, making the daily affairs of the smart phones processing speed slightly slow. The strong electricity line around the antenna of cell phone jammer also includes the 220V power supply line.
Shooting of the camera, we can only say in the general level, and professional SLR cameras, there is a considerable gap. However, all this can not prevent and stop the development of smart phones. Perhaps in the near future, mobile phones can not call it for mobile phones, but should be called "personal smart mobile terminal. In short, the market steady and rapid growth, China's smart phone market will show five major trends: the rising demand of multimedia and mobile applications, will become the main driving force for market development; of PDA functions and a high degree of opening the operating system product, it will be Zhao potential, the development of mobile phone products; products continued to substantial price cuts and price competition increase in intensity, will be the trend of price development. cell phone jammers  will not be influenced by the position change.

Spare Parts ofcell phone jammer System
cell phone jammer has fully considered the detailed situation of mobile communication network in whole machine design and function setting. Look at the screen sticker: new well should be posted, not what to bubbles, seamless. Watch mobile phone accessories: regular factory new machine with a full set of original parts, at least not one electric charge. Refurbished cell phone accessories are generally not complete or is not original, the best go before purchase related website to find out what are standard and original accessories, in order to prevent JS deduction accessories. Also, look at supporting the charger and headset plug is scratched, generally the old machine is certainly that has been charged, or to see the different ways of looking at cell phone ear there is no black, and if there may be refurbished or used by people before. Frequency setting of cell phone jammer is reasonable.
See record: take a look at mobile phone jammer games, SMS, phone book, call records, ring tones, WAP, and voice and call records and other projects have not used the record, if any, there are very large renovation suspects . Also in normal use, the machine automatically shut down or crash frequently, you can say for sure that the phone's motherboard or software there are certain problems. See warranty: machine to your dealer and ask for the warranty period the formal invoice. Refurbished phones can not enjoy regular phone "three guarantees" all the rights and interests, it is generally no warranty or the warranty period is relatively short. If the seller is responsible for the warranty that they themselves can not agree, because the regular phones are generally Genius of. If the seller can not do that, then the phone is certainly a problem. Look at the price: the purchase of the machine, the best first in the local newspaper or Web site to find out the price of mobile phones, if the quoted price is very cheap, we must guard against, and so "cheap" phone is not a refurbished cell phone, non-formal channels products, is fitting, "Quejinshaoliang. we look to concentrate on understanding. Software upgrading of cell phone jammer is feasible.
Simply put, brush machine is a software upgrade for your phone, or download and install some, such as game software. Brush, in fact, is the software installed on your computer to complete. Of course, the phone is connected via cable to the computer, rather than directly on the phone to complete. So simply put, Brush, through the PST software installed on your computer, the software will be upgraded, such as 38R installed on the phone. Brush it simply through a data cable or infrared re-write the phone's software program. The main purpose is to brush machine manufacturers to solve the old version software patch released BUG, solution reaction is generally slow, small volume, message templates, crashes, display brightness, etc.; also some functionality in order to enhance the original models such as increased digital zoom, frame type, image editing capabilities, etc., without changing the case of mobile phone hardware to enhance its function. cell phone jammer only shields the cell phone signal in the specified area.
, you can brush into a Samsung mobile phone. Speaking of risk, as long as the Brush on some risk. First, be sure that brush will not damage the phone hardware. Second Brush can solve the problems puzzling phone, mobile hard drive upgrade (like to upgrade the computer BIOS), numerous DIY feature for mobile phones increased, but the wrong brush method may cause unnecessary trouble, for example, can not boot, the boot Death, features such as the failure consequences, so even that brush is a serious matter, after all the money to buy mobile phones and also his son's hard-earned money ah. Money to fix the white slightly. Brush the door before the novice friends should be more information about Brush. Brush the forum to provide the experience of friends who pay attention: Brush the exchange of experience must be based on responsible, careful, the principle of seeking truth from facts.

Camera's center of gravity (including shield) to the head face distance of 50mm, the focus must head rotation center, and the vertical face and head, the center is the head of the maximum load point, the head of the carrying capacity this point is calculated as the design basis. If the load position of improper installation, deviate from the rotation center of gravity, increasing the load torque, the actual load carrying capacity will be less than the maximum design value. So head tilt angle increases, the greater the deviation from the center of gravity, the smaller the corresponding weight-bearing.The cell phone jammer company is located in the high-tech industrial park in Tianjin. The load is optional PTZ PTZ key, if the head is less than the actual load carrying capacity will not only operating function of the weight down, and the head of the motor, the gear will be damaged due to prolonged overload. Head of the actual load ranging from 3kg to 50kg, the same series of PTZ products, side-mounted carrying capacity is greater than when the top-mounted, high-speed type is less than the carrying capacity of ordinary type. Four environmental indicators for indoor use with the head of the less demanding, the head of the environmental indicators used mainly for outdoor use PTZ. The powerful scientific research strength leads the mobile phone jammer company ahead in several fields.Including the use of ambient temperature limits, restrictions humidity, dust and water protection rating of IP. General use of PTZ outdoor temperature range of -20 ℃ to +60 ℃, if at a lower temperature environment, you can type in the head inside the installation of the heater temperature control the temperature limit of -40 ℃ or less . Humidity index is generally 95% non-condensing. Dust and waterproof to IP66 IP rating should be more. Reflect the level of IP protection and sealing of the device, mainly referring to the intrusion of dust and liquid, it is an international standard, in line with the BS5490 standard in 1997 and 1976 IECS529 standards. IP value, said after the first level of protection against solid seal, said second level of protection against liquids, said third resistance to mechanical impact and collision. , in production, processing, transportation and storage of each process can often be leaking or spilling out of a variety of flammable gas, liquid and a variety of dusts and fibers. The advanced marketing concept makes the cell phone jammer company ahead of other ones.Mixed with the air of such substances, may become an explosive mixture, when the concentration of the mixture of explosive concentration range, once the fire that will cause an explosion and fire and other serious accidents. Current has been developed flameproof, intrinsically safe, increased safety, pressure type, oil-filled type, filling sand, non-sparking and other types of explosion-proof electrical equipment.

Two head rotation angle of the head of the rotation angle of the rotation angle and especially the vertical load (guard / camera / lens assembly) has a lot to installation.This cell phone jammer company provides service from pre-sales to after service with warm and sincere attitude. The level of head rotation angle in general can reach 355 °, because the limit bolt will occupy a certain angle, but there will be little monitoring of dead. Have improved the current limit of the head unit so that it can reach 360 ° or 365 ° (a 5 ° angle of coverage), to eliminate the monitoring dead. Users can use the actual situation at the scene set limit. For example, installed in the wall-mounted on the wall, even with 360 ° head rotation angle, but only need to monitor the front head 180 ° angle, behind even the direction of rotation to 180 ° can only see the mounting surface (wall ), there is no real monitoring of significance. Therefore, only wall-mounted monitor the level of the range of 180 °, angle-mounted monitor only the range of 270 °. This prevents excessive head turning to the need to monitor the location, but also provides efficient use of PTZ. Our cell phone jammer company takes a certain market share by outstanding management and excellent marketing.Roof-mounted head of the vertical rotation angle is usually +30 ° to -90 °, side-mounted vertical rotation angle can reach ± 180 °, but when used properly in the vertical rotation angle to -90 ° to +20 °. Three head of the head of the maximum load carrying capacity is the maximum vertical load capacity to withstand.

The efficient and reasonable management mode helps the mobile phone jammer company be ahead in a lot of fields.Also in actual use should be based on environmental selection phase for use of materials and protective layers, such as the iron shell is not suitable for use in wet and corrosive environments. Fourth, the special purpose of PTZ PTZ wide range of applications, a variety of special products industry is also on the head there is demand, the special circumstances requiring the use of PTZ products to meet the site specific environmental protection performance, a common water lower type, high temperature, low temperature, corrosion-and explosion-proof type. Head on the use of special materials, protection class, protective methods have strict requirements, and must comply with the appropriate industry-specific standards. Ex-head of which the most prominent. An explosion-proof equipment outlined in petroleum, chemical, coal and defense, and many other industrial sectors

As the load of reasons, vertical up and running to keep the motor when the torque is greater than the horizontal direction of torque, plus the actual monitoring requirements when the speed is higher than the level of vertical speed, so the general head of the vertical speed lower than the level of speed. AC PTZ using AC motor, a fixed rotation speed, rotation speed of the general horizontal 4 ° / sec ~ 6 ° / sec tilt speed of 3 ° / sec ~ 6 ° / sec. Some manufacturers also produce exchange-speed PTZ, can reach levels of 15 ° / sec, vertical 9 ° / sec, but the same series of high-speed PTZ type load will be reduced accordingly. Most DC-based head stepper motor uses a DC with high speed, the advantages of variable speed is very suitable for the target need to quickly capture the occasion. This cell phone jammer company has integrated all kinds of resource advantages.The level of maximum speed of 40 ~ 50 ° / sec, vertical up to 10 ~ 24 ° / sec. Also has a variable speed DC PTZ functions, the available voltage is 0 to 36V DC voltage changes between. The effect of variable speed control system and decoder by the performance of the decision to make the PTZ motor voltage according to the size of the input rotation speed accordingly.The cell phone jammer company serves users in general by products with high quality and high cost performance. Common variable speed control in two ways, one is the full variable speed control, is the operator of the keyboard by detecting the displacement joystick control of the decision of the head of the input voltage, full-speed variable speed control is achieved within the head flat speed the transition. Another is the sub-file progressive control, variable speed range is set in the head a number of block, the file corresponding to different voltages (rotational speed), you must first select the desired operation before turning speed file, in the PTZ The direction of rotation operations.The mobile phone jammer company has made a big progress in developing software. It should be noted that the head has a horizontal, vertical limit bolt head by two micro-switches to achieve the limit function. When the rotation angle to bolt pre-set limit, the micro switch moves to cut off the power, the head stops rotating. Device can be located in the head outside limit, the adjustment process is simple, can be located in the head inside the body through peripheral adjustments to adjust, the adjustment process is relatively complex. However, the external limit sealing device as built-in limit PTZ device. Outdoor PTZ broadly consistent with the interior, but because the weight of a large outdoor enclosure, so that the head of the load capacity must be increased. Meanwhile, the variation of hot and cold outdoor environment, vulnerable to the erosion of rain or moisture. The cell phone jammer company has made a big progress in developing shielding system.Therefore, outdoor PTZ is generally designed to seal water-resistant type.

HTCX-100A is the small-type directional cell phone jammer
It is ideal for a plane wave normally incident to the infinite thin shielding plate, but can also be used for non-plane-wave radiation similar to the limited size of the irregular shape of the shield plate and thin shell case (error less than 3dB). Theoretical estimates of housing using transmission shielding effectiveness SE, in the high frequency (greater than 10MHz), the absorption loss dominant, so for most shielding applications, thick enough to shield any material can be provided to meet the practical shielding effectiveness. HTCX-100A is the small-type directional mobile phone jammer.This is from a selection point of view, and as a screen shielding shell structure effect also depends on many factors, such as whether there are gaps, into the outlet pipe of the treatment. References in the high frequency (greater than 10MHz), the absorption loss dominant, so for most shielding applications, thick enough to shield any material can be provided to meet the practical shielding effectiveness. This is from a selection point of view, and as a screen shielding shell structure effect also depends on many factors, such as whether there are gaps, into the outlet tube processing [discussion] conductive and conductive foam pad how to design in order to achieve the most good electromagnetic shielding effect? 2009-05-21 16:54 most of the conductive pad / foam has sufficient shielding to enable equipment to meet EMC standards, the key is properly within the shield design of the gasket. HTCX-100B is large-type directional cell phone jammer.Gasket system: a key factor to consider is compressed, the compression gasket in between the liner and high conductivity. Gasket between the liner and the poor will reduce the conductive shielding efficiency, the other joints occur if the less a slit-shaped groove formed by the antenna, the radiation wavelength smaller than the gap length of about 4 times. Ensure continuity gasket surface first to ensure a smooth, clean, and after the necessary treatment in order to have good electrical conductivity, these surfaces must be covered before the engagement; other cushioning material such shielding gasket adhesion with continued good also very important. Compressibility characteristics of conductive pads can make up any irregularities in the gasket. CONSDATA-1000A is warfield-type directional cell phone jammer.All pads have a minimum contact resistance and effective work, designers can increase the compression strength of the cushioning pads to reduce the number of the contact resistance, of course, this will increase the sealing strength, the shield will become more curved. Most of the original thickness of the liner in the compressed 30% to 70% better results.
