Abstract
A method includes receiving at a wireless access point a first probe request from a first client device requesting connection with the wireless access point via a first frequency band, queueing the first client device in response to an indication that the first client device supports connection via the second frequency band, and in response to receiving at the wireless access point a second probe request from the first client device requesting connection with the wireless access point via the second frequency band, establishing a connection between the wireless access point and the first client device using the second frequency band.
Claims20
A method, comprising:
- receiving at a wireless access point a first probe request from a first client device requesting connection with the wireless access point via a first frequency band;
- in response to determining that the first client device is absent from a block list, detecting an indication that the first client device supports connection via a second frequency band;
- queueing the first client device by adding the first client device to the block list in response to the indication, wherein the block list is implemented as a probabilistic filter;
- and
- in response to receiving at the wireless access point a second probe request from the first client device requesting connection with the wireless access point via the second frequency band, establishing a connection between the wireless access point and the first client device using the second frequency band.
A wireless device, comprising:
- a first wireless core for a first frequency band, configured to receive a first probe request from a first client device requesting connection with the wireless device via the first frequency band;
- a processing unit configured to:
- in response to determining that the first client device is absent from a block list, detect an indication that the first client device supports connection via a second frequency band, and
- queue the first client device in the block list in response to the indication, wherein the block list is implemented using a probabilistic filter;
- and
- a second wireless core for a second frequency band, configured to:
- receive a second probe request from the first client device requesting connection with the wireless device via the second frequency band, and
- in response to receiving the second probe request, establishing a connection between the wireless access point and the first client device using the second frequency band.
A system, comprising:
- a media device;
- and
- a wireless access point coupled with the media device, wherein the wireless access point comprises:
- a dual-band radio configured to:
- receive a first probe request from a first client device requesting connection with the wireless access point via the first frequency band,
- receive a second probe request from the first client device requesting connection with the wireless access point via a second frequency band, and
- in response to receiving the second probe request, establish a connection between the wireless access point and the first client device using the second frequency band, and
- a processing unit configured to
- in response to determining that the first client device is absent from a block list, detect an indication that the first client device supports connection via the second frequency band, and
- queue the first client device in the block list in response to the indication, wherein the block list is implemented using a probabilistic filter.
