An explanation is given of the radio transmission system for realizing a road-automobile communication function within a minimum radio zone (about 50-100 m in diameter). The beacon station having the radio zone is connected to a wire transmission line, thus constituting a wide-area network designed as a packet-switching network. The communication protocol has hierarchical layers with reference to the technological tendency and OSI model of the ISO standard. When the system configuration is established, a nationwide total data communication system can be supported using a pair of frequencies.
