Frequency setting of cell phone jammer is reasonable

Has commercial applications for 2.5G mobile communications technology from 2G into 3G convergence of technology, breakthrough technology for 2G circuit-switched data transmission rate constraints, the introduction of packet switching technology, which allows data transfer rate of a qualitative breakthrough, is a cross between between 2G and 3G over technology. GPRS, HSCSD, WAP, EDGE, Bluetooth (Bluetooth), EPOC and other technologies are 2.5G technology. GPRS (General Packet Radio Services) of Chinese as a general packet radio service, has been hailed as the GSM 2.5G, is a system based on GSM wireless packet switching technology to provide end to end, wide-area wireless IP connection, the speed is 53.6kbps . With "real-time online," "according to the amount of billing," "fast logon", "high-speed transmission," "freely switch" advantages. More simply, GPRS is a high-speed data processing techniques, methods based on "group" in the form of sending data to the user's hand. Although the GPRS network as the existing GSM to third generation mobile communication technology transition of the transition, but in many ways it has significant advantages. The covering radius of cell phone jammer  is large enough.
The use of "packet" technology, Internet users is relatively stable, short-term to avoid unnecessary distress caused. In addition, the method to use GPRS Internet and WAP and different, just as with WAP Internet access at home, the first "dial-up connection", but can not use the Internet Houpian telephone line, but it is more advantageous GPRS, download data and calls can be the same time. Technically speaking, voice transmission (ie call) to continue to use GSM, and data transmission can use GPRS, so, put the mobile phone applications to a higher level. Frequency setting of   cell phone jammer is reasonable.
GPRS due to its immediate online features, for users, can be said that all the time on-line state. GPRS technology can also allow service providers to charge based on the amount of data transmission, rather than simply the time-line billing. The technology and the GSM network with transmission speeds up to 115kbps. System of completely personal responsibility is performed to  cell phone jammer .
