1. A method comprising:
- in a wireless local area network (WLAN) that includes one or more wireless access points capable of serving one or more wireless clients, detecting a presence of one or more instances of interference from a particular type of interferer on at least one channel in an unlicensed frequency band; and
in response to detecting the presence of the one or more instances of the interference, biasing a radio resource management process to continue operation of at least one of the one or more wireless access points on the at least one channel to make at least some use of the at least one channel for the one or more wireless clients by operating the at least one of the one or more wireless access points to create a plurality of WLAN cells to compete with the interference of the particular type of interferer for usage of the unlicensed frequency band, wherein the plurality of WLAN cells includes;
a first type of a WLAN cell that operates on the at least one channel and is served by the at least one of the one or more wireless access points, wherein the at least one of the one or more wireless access points operates at a first transmit power and a first data rate that maximizes coverage for the one or more wireless clients; and
a second type of the WLAN cell that operates on a channel isolated from the at least one channel.

Abstract
In a wireless local area network (WLAN) that includes one or more wireless access points capable of serving one or more wireless clients, presence of one or more instances of interference from a particular type of interferer is detected on at least one channel in an unlicensed frequency band. In response to detecting the interference, a radio resource management process is biased to continue operation of at least one of the one or more access points, or individual radios of a multi-radio access point, on the channel to make at least some use of the channel for one or more wireless clients.

19. An apparatus comprising:
-
a network interface configured to enable communication with one or more wireless local area network (WLAN) access points capable of serving one or more wireless clients, wherein the one or more WLAN access points are configured to detect a presence of one or more instances of interference from a particular type of interferer on at least one channel in an unlicensed frequency band; and a processor coupled to the network interface, wherein the processor is configured to, in response to detection of the presence of the one or more instances of the interference, bias a radio resource management process to continue operation of at least one of the one or more WLAN access points on the at least one channel to make at least some use of the at least one channel for the one or more wireless clients by operating the at least one of the one or more WLAN access points to create a plurality of WLAN cells to compete with the interference of the particular type of interferer for usage of the unlicensed frequency band, wherein the plurality of WLAN cells includes; a first type of a WLAN cell that operates on the at least one channel and is served by the at least one of the one or more WLAN access points, wherein the at least one of the one or more WLAN access points operates at a first transmit power and a first data rate that maximizes coverage for the at least one of the one or more wireless clients; and a second type of the WLAN cell that operates on a channel isolated from the at least one channel. - View Dependent Claims (20)
