Despite significant advances in mobile network technology, it is widely accepted that 2G devices will continue to play a critical role in machine to machine communications in Europe for the foreseeable future. For the exchange of small, regular amounts of data between devices, the GPRS/EDGE networks provide the ideal bearer service, combining the most expansive network coverage with high service reliability. SMS and voice services are also supported, offering a range of communication options at a very attractive price point.
3G devices enhance data throughput capability. HSPA technology provides further improvement in data rates, suitable for applications involving media content for example. Versions of 3G products are available for markets where 2G is unavailable or will have a limited life, such as USA and Australia.
