Abstract:
1. A wireless communication device including: one or more antennas; and a wireless communication unit to scan a first wireless communication frequency band and, upon detecting at least one access point communicating over the first wireless communication frequency band, to receive, from the detected access point, information identifying one or more channels of a second wireless communication frequency band, different from the first wireless communication frequency band, and to scan the identified channels to detect wireless area network communications of at least one wireless area network, wherein the wireless communication unit is to determine a set of channels, including the identified channels, to set a scanning duration to a duration of a predefined beacon interval, and to scan a channel of the set of channels for the scanning duration, wherein, if the wireless communication unit detects a packet over the channel, the wireless communication unit is to monitor the channel for up to a predefined time period, which is longer than the scanning duration, to receive a beacon frame from a control point, wherein, if no beacon frame is received by the wireless communication unit over the channel, the wireless communication unit is to scan another channel of said set of channels for the scanning duration, and wherein, if, after scanning all channels of the set of channels, no beacon frame is received by the wireless communication unit, the wireless communication unit is to increase the scanning duration and repeat the scanning using the increased scanning duration.
