ETSI’s TS 102 636 GeoNetworking Standards Defined
The IEEE 802.11p link layer protocol for Wireless Access in Vehicular Environments (WAVE) in the 5.9 GHz band was derived from the IEEE 802.11 Wi-Fi standard, adding support for Intelligent Transportation Systems (ITS) applications, in particular vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) functionality, as defined in the Dedicated Short-Range Communications (DSRC) protocol, enabling communications between vehicles and roadside access points.
In Europe, 802.11p formed the basis for the European Telecommunications Standards Institute’s (ETSI) ITS-G5 and GeoNetworking network layer protocol standards, the latter concept initially developed in the EU research project GeoNet. The ETSI TC ITS WG3’s family of GeoNetworking standards specify mechanisms for packet forwarding and routing in an ad hoc collection of ITS stations using geographic locations of ITS stations...
