Methods and apparatus for using 802.11 Wireless LANs in TV white space that allow networks with overlapping wireless regions to coexist. The methods and apparatus offer a solution to the mutated hidden node problem. Wireless devices communicate with a coexistence manager over a backhaul connection. Signals are sent by a low power station indicating a request to use a portion of spectrum. The coexistence manager communicates with a plurality of second stations that transmit at a higher power level. The plurality of second stations either send a signal to the first station indicating that it can transmit, or send signals so that the first station can determine which interference it is receiving, after which the coexistence manager tells the interfering station to transmit a signal to the first station indicating when it can transmit. |
