Data transmission via mobile networks is the alternative in the absence of other transmission media such as dedicated lines or telephone networks and wherever it would be too expensive to set up your own radio network. The Siemens portfolio includes modems and routers for the most varied networks (GSM, (E)GPRS and UMTS). The devices provide the highest data security and connection stability with maximum flexibility: independence from telephone lines, many mobile application possibilities, as well as the free selection of service providers. The new UMTS routers from the high-performance product spectrum of SCALANCE M prove themselves with their high bandwidth and make possible applications for Telecontrol, Teleservice and other uses e.g. in the fields of transportation and energy.
