New radio modules combine GPS with GSM technology

6 September 2006 Telecoms, Datacoms, Wireless, IoT

Siemens Communications Group is bringing to market two new modules for tracking and navigation applications: the XT75 and the XT65.

Both modules contain a GPS receiver that allows global positioning, and EDGE or GPRS technology for transmitting data to a mobile device. The modules, which will be available in December, are based on Java and have quadband capability, making them usable in all GSM mobile networks worldwide.

The XT75 and XT65 radio modules are especially suited for fleet management, vehicle positioning, navigation, emergency call or location-based services. They allow the user to determine the exact location of persons, vehicles, goods in transit or end devices. Location-related information can also be sent and called up via the mobile network. A car driver, for example, can thus load information on the nearest restaurant in a navigation system or send an emergency SMS with position data.

According to Siemens, the satellite positioning is fast, carried out via 16 parallel channels using A-GPS data. The integrated TCP/IP communication protocol (TCP/IP stack) converts the A-GPS data into data packets and then transmits these via EDGE (XT75) or GPRS (XT75 and XT65) technology to the mobile network. Both modules send and receive on the frequencies 850, 900, 1800 and 1900 MHz. The XT75 can send data packets at up to three times the speed of ISDN. An integrated RIL driver ensures simple connection to end devices based on MS Windows Mobile.

With Java support for the XT75 and XT65, programming all the applications is fast and easy for developers. All standard sensors and actuators can be linked via digital and analog interfaces.

The modules measure 54 x 39 x 3,5 mm in size and use various GSM and GPS energy-saving modes to minimise power consumption.
