design liaison meeting of cellular phone jammer

By using “packet” technology, user access is relatively stable, short-term to avoid unnecessary distress caused. In addition, the use of GPRS and WAP and the Internet in different ways, as with WAP Internet access at home, the first “dial-up connection”, while the Internet can not be used after the phone line, but it is more advantageous GPRS, download data and calls can be the same time. All the technical personnel are required to take part in the design liaison meeting of   cellular phone jammer .
Technically, the sound transmission (ie, calls) to continue to use GSM, and data transmission can use GPRS, so, put the mobile phone applications to a higher level. And the development of GPRS technology is also very “economic” because only use the existing GSM network to develop to. GPRS wide range of uses, including through the phone to send and receive e-mail, Internet browsing. The experts are holding the meeting to improve technology of   cell phone jammer     .
With the support of CDMA network, China Unicom can achieve a number of new value-added data services, which may win more CDMA users. Currently, the mobile phone standard including GSM, CDMA, 3G three, since the advent of mobile phones has gone through a first-generation analogue phones (1G), second-generation GSM, TDMA digital mobile phones, etc. (2G), 2.5G mobile communication technology CDMA and third generation mobile communication technology 3G. The analog network: analog network signals to analog modulation, the analog series uses frequency division multiple access. (Under the band of mobile 905-915MHZ, each 25KHZ to channels, support for a user calls). The leaders are researching the quality of   cell phone jammer .
A simulated network with China Network (Motorola equipment) and B networks (Ericsson equipment) of the points, now have two networks to interoperate. Analog network signal distortion is small, so the sound quality with limited phone Bimei. And because the building earlier, coverage improved in most county-level cities are covered. The disadvantage of the analog network is a relatively small number of its channels, poor security.
