An IEEE wireless standard for operation in the VHF and UHF TV white space bands from 54 to 862 MHz. Employing cognitive radio techniques, 802.22 is a "wireless regional area network" (WRAN) and is dubbed "Super Wi-Fi."Similar to 802.11afThe IEEE 802.11af Wi-Fi standard also uses the TV white spaces but 802.22 offers greater distances and higher data rates (up to 100 km and 50+ Mbps compared to 1 km and 25+ Mbps). Both technologies penetrate walls better than regular Wi-Fi due to their lower frequencies. See 802.11af, TV white spaces and cognitive radio.
The IEEE Working Group on Wireless Regional Area Networks (WRANs). 802.22 is an initiative directed toward the development of a cognitive radio air interface for use by license-exempt radios on a non-interfering basis in spectrum currently allocated to television broadcast service.
