After an introduction to ITS and the wireless communication requirements for the different ITS applications, the report summarises the overseas radiocommunications regulatory arrangements supporting 5.9 ITS and describes the technical and system requirements for On Board Units (OBU) and Road Side Units (RSU) of 5.9 ITS. By assessing the various wireless access technologies for ITS, the report shows that there is a clear need in 5.9 GHz and future need in 700 MHz and 63 GHz to enhance 5.9 ITS. After a summary of relevant previous studies regarding interoperability between 5.9 ITS and other services in the 5.850 to 5.925 GHz band and its adjacent bands, this report summarises the Australian environment of frequency usage around 5.9 GHz, and analyses the interference of 5.9 ITS to existing services and vice versa.
