Wireless LAN  Wi-Fi a/b/g/n  DSRC p (Vehicular DOT network - dedicated short range communications)  Fixed Wireless Data  Wi-Fi a/b/g/n  DSRC p (Vehicular DOT network - dedicated short range communications)  Fixed Wireless Data

Fixed Wireless Data  Fixed Wireless Data is a class of technologies used to connect two fixed locations (e.g., buildings) with a radio or other wireless link, such as laser bridge. Usually Fixed Wireless Data is part of a Wireless LAN infrastructure. The purpose of a Fixed Wireless Data link is to enable data communications between the two sites or buildings. Fixed Wireless Data links are often a cost-effective alternative to leasing fiber or installing cables between the buildings.

DSRC  Dedicated Short Range Communications is a short to medium range wireless protocol specifically designed for automotive use. It offers communication between the vehicle and roadside equipment. It is a sub-set of the RFID-technology.  5.9 GHz band (U.S.)  Emergency warning system for vehicles  Cooperative Adaptive Cruise Control  Cooperative Forward Collision Warning  Approaching emergency vehicle warning (Blue Waves)  Dedicated Short Range Communications is a short to medium range wireless protocol specifically designed for automotive use.
