IEEE 802.11p is an approved amendment to the IEEE 802.11 standard to add wireless access in vehicular environments (WAVE), a vehicular communication system. It defines enhancements to 802.11 (the basis of products marketed as Wi-Fi ) required to support intelligent transportation systems (ITS) applications.
IEEE 802.11ai is an amendment to the 802.11 standard that added new mechanisms for a faster initial link setup time. 802.11aj. IEEE 802.11aj is a derivative of 802.11ad for use in the 45 GHz unlicensed spectrum available in some regions of the world (specifically China); it also provides additional capabilities for use in the 60 GHz band.

May 25, 2006 · This amendment defines modifications to both the IEEE 802.11 Medium Access Control layer (MAC) and Physical Layers (PHY) to enable the operation of an Ambient Power communication (AMP) station (STA) that is powered using energy harvesting. Operation in sub-1 Gigahertz (GHz) and 2.4 GHz is defined. Specifically, at least one mode of data ...
From 2004 onwards the Institute Electrical and Electronics Engineers (IEEE) started to work on wireless access for vehicles under the umbrella of their standards family IEEE 802.11 for Wireless Local Area Networks (WLAN). Their initial standard for wireless communication for vehicles is known as IEEE 802.11p and is based on the work done by the ...
In the U.S., the IEEE 1609 WAVE Wireless Access in Vehicular Environments protocol stack builds on IEEE 802.11p WLAN operating on seven reserved channels in the 5.9 GHz frequency band. The WAVE protocol stack is designed to provide multi-channel operation (even for vehicles equipped with only a single radio), security, and lightweight ...
