Abstract
Methods and apparatuses enable selective operation in an extended bandwidth channel of a wireless communication band. For example, a client station can be selectively authorized to operate on a 40 MHz channel in a 2.4 GHz band. The client station or an access point or both can determine whether interference exists in the wireless communication band. If potential interference exists, the client station may operate on a non-extended bandwidth channel. If potential interference does not exist, the client station may operate on an extended bandwidth channel. Operation between the two channels can be dynamic based on continued monitoring of the wireless communication band for potential interference.
Claims13
A method comprising:
- determining to assign a client station an extended bandwidth channel in a wireless communication band of a wireless communication system;
- receiving an indication from the client station that the client station detected interference in the extended bandwidth channel of the wireless communication band;
- restricting operation of the client station to a non-extended bandwidth channel in response to the indication from the client station that interference exists on the extended bandwidth channel, wherein restricting operation of the client station to the non-extended bandwidth channel includes:
- waiting for a re-test trigger that indicates the extended bandwidth channel should be re-measured to determine if interference exists on the extended bandwidth channel;
- determining whether interference exists on the extended bandwidth channel in response to the re-test trigger;
- and
- switching from operation on the non-extended bandwidth channel to operation on the extended bandwidth channel if it is determined that interference does not exist on the extended bandwidth channel;
- and
- authorizing operation of the client station on the extended bandwidth channel when interference does not exist on the extended bandwidth channel.
An article of manufacture comprising a non-transmission machine-readable storage medium having content stored thereon to provide instructions to cause a machine to perform operations including:
- determining to assign a client station an extended bandwidth channel in a wireless communication band of a wireless communication system;
- receiving an indication from the client station that the client station detected interference in the extended bandwidth channel of the wireless communication band;
- restricting operation of the client station to a non-extended bandwidth channel in response to the indication from the client station that interference exists on the extended bandwidth channel, wherein restricting operation of the client station to the non-extended bandwidth channel includes:
- waiting for a re-test trigger that indicates the extended bandwidth channel should be re-measured to determine if interference exists on the extended bandwidth channel;
- determining whether interference exists on the extended bandwidth channel in response to the re-test trigger, and
- switching from operation on the non-extended bandwidth channel to operation on the extended bandwidth channel if it is determined that interference that interference does not exist on the extended bandwidth channel;
- and
- authorizing operating of the client station on the extended bandwidth channel when interference does not exist on the extended bandwidth channel.
A wireless client station device comprising:
- a transceiver to transmit and receive wireless signals;
- a channel measuring module coupled to the transceiver to determine whether interference exists in a wireless communication band of a wireless communication system that operates in the 2.4 GHz band;
- and
- a communication processor coupled to the transceiver and the channel measuring module to generate a request for a channel of a wireless communication band of a wireless communication system from an access point, indicate interference to the access point in response to detecting interference in the wireless communication band, and operate on a non-extended bandwidth channel if interference is detected in the wireless communication band and operate on an extended bandwidth channel if interference is not detected in the wireless communication band, wherein to operate in the non-extended bandwidth channel if interference is not detected further includes the client station to operate in the non-extended bandwidth in response to detecting that transmissions from another client station operating in the wireless communication band exceeds a threshold duty cycle time, and to change back from operating in the non-extended bandwidth channel to operating in the extended bandwidth channel in response to detecting a reduction in the interference.
