SHORT-RANGE VEHICLE TO ROADSIDE COMMUNICATIONS AT 5.8 GHZ

A critical element of intelligent transportation systems (ITS) is the communications path between vehicles and the roadway infrastructure. A large quantity and wide variety of information must be exchanged between these two domains. At typical highway speeds, the time available to transfer data is limited and the amount of data and density of reporting points that are involved makes the use of wide-area, two-way systems impractical. The most critical issue for such a system is radio spectrum availability. In the US, the band 5850-5925 MHz has been allocated for use by ITS systems. This paper discusses system performance and spectrum efficiency requirements for a dedicated, short-range vehicle to roadside communications system. It also describes testing and analyses that have been completed to ensure compatibility with other users in the band. (a) For the covering entry of this conference, please see IRRD abstract no.
