Neighbor scanning in wireless local area networks


Abstract

An access point includes a transmitter configured to transmit signals, a receiver configured to receive signals, and a timing information device. The timing information device is configured to receive a timing information request from a station associated to the access point, receive timing information for a beacon signal sent by a second access point, and report the timing information to the station. The timing information includes a time difference relative to a known reference time for transmission of the beacon signal and the time difference is an offset in timing units.
