Siemens is bringing more than ISDN speed to vehicles with its AC45 mobile radio module that was specially developed for the automobile sector. It can be integrated in navigation equipment, radios, fleet management systems, and telematic boxes, providing the basis for applications such as Internet, emergency and breakdown calls, and stolen vehicle tracking.
Alongside voice, the dualband-enabled AC45 mobile radio module permits net data transmission rates of up to 85.6Kbps in downloading, which is faster than the rate offered by an ISDN connection.
"High-speed GPRS technology will make it possible for people to download images and graphics from the mobile radio network - and very quickly," explained Jos'e Costa e Silva, President of Wireless Modules within the Information and Communication Mobile Group. This will make applications possible such as GPS navigation on demand, retrieving messages and e-mails in vehicles, remote diagnosis, and also, for instance, downloading electronic city information, maps, and images.
The GPRS technology from Siemens has been tested and qualified for all leading network carriers and their network infrastructures.
The AC45 conforms to GPRS Class 8, including Packet Broadcast Control Channel (PBCCH); it has also obtained all the approvals and passed all the tests for the international market (R&TTE certificate, GCF approval, and the E mark for vehicle use), so all that is needed is low-cost, quickly performed delta approval for the application. The GSM/GPRS module is very robustly designed for use in vehicles and can operate within a temperature range of -29^0 to +75^0 Celsius. Integrated features are hands-free talking conforming to the VDMA standard, a freely configurable telephone book, and active power management that can reduce power consumption to about 50.
Samples of the AC45 will be available in January 2003. Serial production will start in March 2003, after which the GSM/GPRS modules will be delivered to leading suppliers of the automobile industry.
