ABSTRACT:
An electronic toll collection (ETC) system comprises an on-vehicle unit mounted on a vehicle and a stationary-station communication system. This communication system operates to perform communication for accounting processing toward the on-vehicle unit mounted on the vehicle that passes a predetermined communication area. The stationary-station communication system comprises a controller and an antenna unit. The controller includes a protocol controller configured to produce a protocol selection signal and a communication controller configured to control the communication based on the produced communication protocol selection signal. The antenna unit includes a modem unit configured to selectively have a plurality of types of modulation/demodulation techniques corresponding to a plurality of types of protocols for the communication and control means configured to selectively allow the modem unit to be switched into a particular modulation/demodulation technique specified by the protocol selection signal.
