IEEE 802.11af, also referred to as White-Fi and Super Wi-Fi,[1][2] is a wireless computer networking standard in the 802.11 family, that allows wireless local area network (WLAN) operation in TV white space spectrum in the VHF and UHF bands between 54 and 790 MHz.[3] The standard was approved in February 2014.[4] Cognitive radio technology is used to transmit on unused portions of TV channel band allocations, with the standard taking measures to limit interference for primary users, such as analog TV, digital TV, and wireless microphones.[3]
