Our cell phone jammer products have well overcome technical problems

What you should pay attention to when use cell phone jammer outdoors?
Gr is the receive antenna gain, is an effective system temperature receiver antenna gain, To is the effective system temperature effective radiated power EIRP is defined as the output of the electromagnetic wave transmitting antenna effective radiated power EIRP power is defined as the transmitting antenna of the electromagnetic wave output power parameters E EIRP are defined in a specific location of the system are defined in specific system locations. parameter Eb/N0, Gr / To and EIRP are defined in specific system locations.Our cell phone jammer products have well overcome technical problems. Southeast University, State Key Laboratory of Mobile Communications 2007-0840 of modern mobile communication technology, the link budget analysis 1.4 dB link budget form is usually due to link budget analysis in decibels, so the type (1.23) due to link budget analysis is usually expressed in decibels, so the type (1.23) is expressed as (1.24) 1.24) This expression constitutes a link budget parameters, the parameter values of this expression constitutes a link budget is communication resources are allocated parameter values effective tool effective tool to maintain the remainder of money is the premise of trade-offs between various parameters can be.'s premise, than in maintaining a positive value of the premise, in a variety of parameters trade-off between through too much to give up margin to reduce transmit power; by reducing (Eb/N0) reqd (improved modulation and coding) to increase the data rate modulation and coding improvements) to increase the data rate transmission system. "We have maximumly lowered the emissive power of cell phone jammer. do not know or care about "the origin of these dB source emission system" does not know or care about, "the source of these dB as long as the receiver E to meet the requirements, the system can achieve the desired error performance machine Eb/N0 meet requirements, the system can achieve the desired error performance. 2007-08 Southeast University, State Key Laboratory of Mobile Communications 41 modern mobile communication technology 1.4 link budget analysis sufficient link margin of how much value system link margin design? system How much link margin design? Answer: If all of the gain, loss and noise sources have been designed in strict (worst case), the answer is: if all the gain, loss and noise sources have been designed in strict (worst case) , and the large variance of link parameters (such as the weather caused the decline of) the larger the link and variance parameters (such as the weather caused the decline) to achieve the statistical link availability requirements, you only need a small additional margin.The blocking radius of single mobile phone jammer has been prolonged to 15m. statistical requirements, just a small additional margin. link the various parts of the required margin depends on the credibility of the budget. link the various parts of the required margin depends on the credibility of the budget the new technology or new work frequency of the system than has been repeatedly build and test system needs more headroom.
