Siemens Wireless Modules' MC75 is the first GSM/GPRS radio module featuring EDGE technology, which is currently the fastest data transfer standard in worldwide GSM networks.
EDGE, for 'Enhanced Data Rates for GSM Evolution' allows downloads and streaming of data-intensive multimedia files, exchange of e-mail attachments and fast Internet or intranet access. Thanks to EDGE, users can easily conduct their business activities on the Internet, or on the company intranet, using their smartphone, PDA or laptop PC - in fact, this can be done three times faster than when using GPRS; EDGE theoretically has a maximum bit rate of 474 Kbps compared to GPRS that has 171 Kbps.
As GSM evolves in the direction of UMTS, the EDGE standard's role is growing increasingly important. As a supplement or alternative to UMTS, it offers high data transfer rates and a significantly better utilisation of network capacity without any additional investments in the existing infrastructure being necessary. While the UMTS infrastructure is still being developed, EDGE already ensures a global coverage even in rural areas. In areas where there is still no UMTS infrastructure, EDGE can fill regional gaps during the transition period until UMTS is launched. In addition, EDGE offers mobile network operators without a UMTS licence a cost-effective high-speed alternative.
In order to fully utilise the fast EDGE technology globally, next generation mobile phones and computers need an additional frequency range. The MC75 is thus equipped with quadband GSM (850/900/1800/1900 MHz), which means it can be used on all existing GSM networks. With an integrated RIL/NDIS driver, the MC75 is especially suited for smartphones and PDAs based on the Microsoft Windows Mobile operating system.
The MC75 includes a USB connection allowing plug and play. The lead-free unit is also extremely compact at 34 x 45 x 3,5 mm, and is lightweight at under 10 grams.
