EDGE MODEM -

1.   General 

Further enhancements to GSM networks are provided by Enhanced Datarates for GSM Evolution (EDGE) technology. EDGE provides up to three times the data capacity of GPRS. Using EDGE, operators can handle three times more subscribers than GPRS;triple their data rate per subscriber, or add extra capacity totheir voice communications. EDGE uses the same TDMA (Time DivisionMultiple Access) frame structure, logic channel and 200 kHz carrierbandwidth as today's GSM networks, which allows it to be overlaiddirectly onto an existing GSM network. For many existing GSM/GPRSnetworks, EDGE is a simple software-upgrade.

EDGE allows the delivery of advanced mobile services such as thedownloading of video and music clips, full multimedia messaging,high-speed color Internet access and e-mail on the move.

Due to the very small incremental cost of including EDGE capabilityin GSM network deployment, virtually all new GSM infrastructuredeployments are also EDGE capable and nearly all new mid- tohigh-level GSM devices also include EDGE radio technology.

 The Global mobileSuppliers Association (GSA) states that, as of May 2007, there were223 commercial GSM/EDGE networks in 113 countries, from a total of287 mobile network operator commitments in 142 countries

The GF-6000W EDGE/GPRS Modem developed by Beijing GarefowlTechnology Co., Ltd. It provides mobile user’s access to Internetand can be connected directly to personal PC via serial portinterface. Co-working with dialup software, the modem canautomatically detect link status and redial if the linkdisconnects. It is a highly reliable link satisfying requirementsof industrial data transmission.
