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.
