TransCore modem performs DRSC, GPS, satellite communications

Posted by iNext - 2005-11-08

MANHASSET, N.Y. — RFID product supplier TransCore has developed a modem that combines the ability to perform dedicated short-range communications (DSRC) as well as long-range GPS and satellite communications for automobile safety products.

TransCore (Dallas) is one of several companies demonstrating next-generation DRSC technology at the ITS World Congress in San Francisco this week. The company is part of the DRSC industry consortium, whose other members include MARK IV, Raytheon, and Sirit Inc. Consortium members are building prototype devices under contract to the U.S. Dept. of Transportation.

TransCore’s modem will also provide a more immediate means to support critical safety applications while the nationwide short-range communications (DSRC) infrastructure network is built out over the next few decades. As DSRC infrastructure becomes available, the system will take advantage of its low usage costs and tailored communication capabilities. In areas without DSRC, either the satellite communications capability or a conventional cellular link can be used to connect to the vehicle.

Moving from multiple in-vehicle components to a highly integrated device will lower cost and provide ubiquitous coverage, according to TransCore (Dallas).

"This is precisely the right combination of technologies and platform to bring a vast array of safety applications into the automobile," said Kelly Gravelle, TransCore's chief technology officer, in a statement. "Instead of building something from pieces and parts or limited to short-range communications, vehicle OEMs can incorporate a single integrated component into the vehicle with the attendant cost savings, space reduction and improved reliability."

With GPS accuracy of up to one meter and the versatility of multiple channels to communicate with the vehicle, the modem will enable safety services in the near term as well as the foreseeable future. The modem will allow automated reporting of incidents, irrespective of the limitations of local terrestrial coverage. These technologies will allow auto OEMs to deliver integrated preventative safety systems such as automated warnings and collision avoidance for fire, ambulance and police response.

Incorporating satellite technology was an essential element of TransCore's strategic vision o combine the inherent advantages of both short- and long-range communication devices. TransCore will team with Ottawa, Canada-based Carleton University to develop advanced radio frequency (RF) circuit integration technologies, central to making the resulting product viable and cost effective.

Besides the U.S. Dept. of Transportation, TransCore's approach leverages other ongoing initiatives, such as the GPS technology supported by the European Space Agency, and satellite communication/GPS technology supported by the Canadian Space Agency.
