WAVE (Wireless Access I Vehicular Environment) is a next generation Dedicated short Range Communication (DSRC) technology.

Data rate of 3-27 Mbps even in fast moving environments.

802.11p/DSRC technology is the basis for future Intelligent Transportation Systems.

The number of 802.11p/DSRC devices, available in the international market are very few and generally the price exceeds 5000 USD.
