3. Intelligent transport systems - Dedicated short range communications at 5.8 GHz - Recommendation M
This Recommendation outlines the technologies and characteristics for dedicated short range communications (DSRC) in the 5.8 GHz band. This Recommendation includes an active (transceiver) method and a backscatter (transponder) method as DSRC technologies available for intelligent transport systems (ITS). This Recommendation further includes a DSRC-application sub layer (DSRC-ASL) which allows for multiple DSRC applications and IP based (Internet protocol) network applications. The technical and operational characteristics of both methods and the DSRC-ASL are described.
Approved June 2005

4. Millimetre wave vehicular collision avoidance radars and radiocommunication systems for intelligent transport system applications - Recommendation M
This Recommendation provides system requirements, technical and operational characteristics of millimetre wave radiocommunication systems for intelligent transport system applications to be used for system design objectives. The Recommendation covers vehicular collision avoidance radar operating in the GHz and GHz bands, as well as integrated millimetre wave radiocommunication systems for ITS applications in the GHz range for vehicle-to-vehicle radiocommunications and radiocommunications between the vehicle and roadside infrastructure.
Approved May 2012

5. Systems characteristics and compatibility of automotive radars operating in the frequency band GHz for sharing studies - Report M
It is expected that any potential cases of interference between automotive radars and incumbent services could be addressed by mitigation factors such as terrain shielding, emission power limits and quiet zones. Some areas of concern remain and may need to be further analysed and dealt with by administrations. It is anticipated that the radio astronomers, radio amateurs and the automotive radar manufacturers will continue their cooperative effort to examine and implement mitigation techniques that can be employed to address potential interference concerns.
Approved November 2014

6. Advanced intelligent transport systems (ITS) radiocommunication - Report M.2228-1
Advanced ITS have enhanced vehicular networking functionality to provide vehicle-to-vehicle communication (V2V), vehicle-to-infrastructure communication (V2I), in-vehicle network (IVN) and vehicle-to-nomadic devices (V2N). Enhanced vehicular networking functionality of advanced ITS also includes accurate location information with ID authentication and data encryption in the vehicle terminal. The vehicular networking is the basic requirement on the vehicle terminal for vehicle safety and new Intelligent Transport System applications. V2N allows hand-held devices to be used in vehicular environment as they are used in home and office environment. Regarding radiocommunication aspects, advanced Intelligent Transport System radiocommunications support both V2V and V2I communications with improved performance in terms of radio coverage, packet data rate, packet size and latency.
Approved July 2015

7. Systems characteristics of automotive radars operating in the frequency band GHz for intelligent transport systems applications - Recommendation M
This Recommendation specifies the system characteristics of automotive radars operating under the radiolocation service in the frequency band GHz. These technical and operational characteristics should be used in compatibility studies between automotive radars operating in the radiolocation service and systems operating in other services.
Approved February 2014
WP 5B is currently developing a draft revision of Recommendation ITU-R M
