A receiver is tuned to a first channel in a plurality of channels, and at least one beacon signal from at least one other channel is received while the receiver is tuned to the first channel. The at least one other channel is determined to be active based on the at least one beacon signal received while the receiver is tuned to the first channel. A channel that is determined to be“active”may be, for example, a communication channel on which an access point in a communication network is communicating or is able to communicate. |
