-Band Module Unveiled"> Tri-Band Module Unveiled Siemens AGs Siemens Mobile unveiled a new tri-band wireless communications module for handling tracking functions in various enterprise applications.The technology, contained on a PC board, is designed to perform tracking functions in applications such as fleet management, vehicle positioning, navigation, and emergency and location-based services. GPS can determine the location of, say, a truck hauling freight. That data is transmitted via GSM/GPRS.
The XT55 GSM/GPRS/ GPS module integrates the GSM (Global System for Mobile Communications) and GPRS (General Packet Radio Service) mobile communications technologies with GPS (Global Positioning System) satellite localization. Siemens, based in Munich, Germany, claims to have developed the first technology that does this.
