The Siemens MC75 wireless module is the first GSM/GPRS radio module featuring EDGE technology, which is currently the fastest data transfer standard in worldwide GSM networks. EDGE (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 with 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 license a cost-effective high-speed alternative.
Whether on private or business trips, continental borders are no longer a hindrance for individuals, IT or mobile telecommunications. This has only been the case since PCMCIA cards, GSM/GPRS modems, and cellphones were equipped with triband technology. In order to fully utilise the fast EDGE technology in every area of the world, mobile phones and mobile computers of the next generation need an additional frequency range. The MC75 is therefore equipped with quadband GSM, which means it can be used in all existing GSM networks. Fast data transfer via EDGE is thus available to continent hoppers everywhere and via the best possible route.
Thanks to the integrated RIL/NDIS driver, the MC75 is especially suited for smartphones and PDAs based on the Microsoft Windows Mobile operating system. This ensures optimal communication between the operating system and the module.
The MC75 includes a USB connection allowing plug-and-play, which is particularly convenient when using GSM/GPRS modems. Further benefits of integrating the module into all mobile communication solutions include its extremely compact size of 34 x 45 x 3,5 mm, the one-sided layout of the printed circuit board's components, and its light weight of less than 10 grams.
In addition, the MC75 provides the approvals necessary for worldwide use free of charge. Thus, it meets requirements in accordance with R&TTE, FCC, IC, UL, GCF, and PTCRB as well as any country-specific requirements, which network providers may have. This makes it possible for manufacturers to reduce their application development costs as well as their total cost of ownership. The MC75 facilitates a faster launch of mobile computing applications and smartphones on the world market.
And last but not least, the MC75 is lead-free, in accordance with the EU Directive on the Restriction of Specific Hazardous Substances in Electrical and Electronic Equipment (RoHS).
The main features of the MC75 include:
* Quadband GSM (850/900/1800/1900 MHz).
* EDGE (E-GPRS) Multislot Class 10.
* GPRS Class 12.
* RIL\NDIS driver for Microsoft Windows Mobile-based devices.
* Fully compatible with USB 2.0 full speed.
