Abstract

According to one embodiment, a method for wireless communication includes performing a first scan of a plurality of wireless channels of a wireless communication network by simultaneously utilizing at least two radios of a base station. The method also includes determining a channel quality metric for at least two of the wireless channels in response to the first scan. The method further includes selecting a first wireless channel of the plurality of wireless channels in response to determining the channel quality metrics. In addition, the method includes communicating on the first wireless channel utilizing the at least two radios of the base station.

8. A method for wireless communication, comprising:

establishing a communication session with a network access device, the network access device providing access to a wired communication network;

receiving information for provisioning a plurality of wireless channels of a wireless communication network from the wired communication network, the information including a parameter for narrowing a frequency range of a scan of the plurality of wireless channels to a range allocated from among an entire frequency band;

communicating on a first wireless channel of the plurality of wireless channels utilizing at least two radios of a base station;

stopping a first radio of the at least two radios from communicating on the first wireless channel;

based on the received information, performing a first scan of the plurality of wireless channels utilizing the first radio;

determining a channel quality metric for at least one wireless channel of the plurality of wireless channels in response to the first scan;

selecting a second wireless channel of the plurality of wireless channels in response to determining the channel quality metric; and

communicating on the second wireless channel utilizing the at least two radios of the base station.

9. The method of claim 8 , wherein communicating on the second wireless channel utilizing the at least two radios comprises communicating with a mobile station.
