Abstract :
The paper describes the medium of "Non-Coherent Infrared Light" as a viable "high speed" alternative to radio-LAN technologies for communications between vehicles and the roadside infrastructure respectively between vehicles. The overload of the radio-spectrum on the one hand and the virtually unlimited bandwidth of infrared light as well as the absence of regulations and licensing cost in most parts of the world on the other hand make infrared the ideal choice in ITS as well as in corporate communications systems for distances up to a few hundred meters at bandwidths up to 500 Mbps and more. The properties and limitations of infrared light in an ITS-environment are the main subject of the paper. Examples of implemented systems are given, too, as well as the standardisation process in progress.
