Wireless networking in TV white space leveraging Wi-Fi

Recently, many standardization activities are in progress to extend Wi-Fi operation to the available unlicensed TV spectrum, i.e., 54-698 MHz. TV channel scanning for incumbent detection is crucial for operation in the TV band and we propose IEs (Information Element) that assist an AP (Access Point) in delegating channel scanning operation to the associated STAs (STAtion) so that it is always available for remedial action if an incumbent arrives on the channel on which the BSS (Basic Service Set) is operational. Also, TV channels are of 6 MHz width and we propose IEs that assist in channel bonding negotiations between two Wi-Fi devices operating in the TV spectrum. The proposed IEs are transmitted by the Wi-Fi devices using the Action frames defined in the IEEE 802.11 standard.
