TransCore to Develop DSRC, GPS, and Satellite Combined Communications Modem |

SAN FRANCISCO, Nov. 11, 2005/Satnews Daily/ — TransCore, one of the largest manufacturer of transportation-based radio frequency identification (RFID) products, said it is developing a combined dedicated short-range communications (DSRC) and long-range GPS and satellite communications modem for automobile safety products.
TransCore said moving from multiple in-vehicle components to a highly integrated device will lower cost and provide ubiquitous coverage.
“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. “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.”
TransCore said the 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.
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 new modem, according to TransCore, will not only be capable of using wideband DSRC locally for control and warnings (e.g., enabling "smart intersections"), but via its GPS and satellite communications technology it will allow automated reporting of incidents, irrespective of the limitations of local terrestrial coverage.
