802.11p-2010 is the IEEE amendment for Wireless Access in Vehicular Environments, extending the 802.11 wireless LAN MAC and PHY specifications for communication between moving vehicles and roadside infrastructure. It is relevant to communication, networking and broadcast technologies, as well as computing and processing, where low-latency, short-range radio links support coordinated transport systems. As a superseded standard, it remains useful for understanding the technical basis of vehicle-to-vehicle and vehicle-to-roadside wireless design.

About 802.11p-2010

This standard defines an amendment to the IEEE 802.11 family that focuses on vehicular wireless communication. 802.11p-2010 addresses how the MAC and PHY layers are adapted for operation in high-mobility environments, where fast-changing signal conditions and brief connection times are common. It is closely associated with dedicated short-range communication use cases and provides a technical framework for interoperability, implementation planning, and conformance-oriented review within wireless networking systems.

Where is 802.11p-2010 used?

802.11p-2010 is typically used in vehicular communication equipment and related roadside systems that exchange data with nearby vehicles. Its context includes on-board units, roadside units, and wireless modules designed for transport coordination, traffic information exchange, and safety-oriented messaging. In practice, the standard is relevant to system integrators, network engineers, and procurement teams evaluating radio interfaces for roadway infrastructure or embedded communications platforms that must operate reliably in mobile environments.

Importance in practice

For organizations working with vehicular wireless systems, 802.11p-2010 helps establish a consistent technical reference for design and testing. Using a defined standard can reduce interoperability risk, support procurement decisions, and improve confidence in performance expectations across different implementations. Because the document is now superseded, it is especially valuable when maintaining legacy equipment, reviewing earlier deployments, or comparing historical design requirements against newer communication approaches in connected transport projects.
