Abstract
Systems and methods are provided by which all APs in a particular deployment can be used to assist in the out-of-band discovery of 6 GHz radios by client devices. That is, a series of iterative operations can be performed to: (I) determine the state of 6 GHz radios in a zone/deployment area; (II) identify what radios can be considered near-neighbors to non-6 GHz radios for purposes of advertising one or more of the 6 GHz radios; (Ill) rank neighboring 6 GHz radios for a given non-6 GHz radio based on certain radio metrics; and (IV) ultimately determine those 6 GHz radios that can be advertised by the given non-6 GHz radio.
Claims20
A method for identifying near-neighbor non-6 GHz radios in a radio frequency (RF) zone of a wireless local area network (WLAN) through which one or more of the 6 GHz radios in the WLAN may be advertised for out-of-band discovery, the method comprising:
- identifying a first set of non-6 GHz radios collocated with a first set of 6 GHz radios that a given non-6 GHz radio considers to be near-neighbors;
- identifying a second set of non-6 GHz radios collocated with a second set of 6 GHz radios that consider the given non-6 GHz radio to be a near-neighbor;
- identifying a third set of non-6 GHz radios collocated with a third set of 6 GHz radios that client devices of the given non-6 GHz radio consider to be near-neighbors;
- identifying a fourth set of non-6 GHz radios collocated with a fourth set of 6 GHz radios that consider client devices of the given non-6 GHz radio to be near-neighbors;
- based on the identifying of the first, second, third, and fourth sets of non-6 GHz radios, creating, by an access point (AP) controller in the WLAN, an ordered near-neighbor 6 GHz radios list ranking 6 GHz radios in the RF zone for the given non-6 GHz radio:
- and
- disseminating, by the AP controller, the ordered near-neighbor 6 GHz radios list to the given non-6 GHz radio.
An access point (AP) operating in a wireless local area network (WLAN), comprising:
- a first non-6 GHz radio, wherein the AP does not include a 6 GHz radio;
- a processor;
- and
- a memory unit including computer code that when executed causes the processor to execute a method of identifying near-neighbor non-6 GHz radios in a radio frequency (RF) zone of the WLAN through which one or more of the 6 GHz radios in the WLAN may be advertised for out-of-band discovery, the method comprising:
- identifying a first set of non-6 GHz radios collocated with a first set of 6 GHz radios that the first non-6 GHz radio considers to be near-neighbors;
- identifying a second set of non-6 GHz radios collocated with a second set of 6 GHz radios that consider the first non-6 GHz radio to be a near-neighbor;
- identifying a third set of non-6 GHz radios collocated with a third set of 6 GHz radios that client devices of the first non-6 GHz radio consider to be near-neighbors;
- identifying a fourth set of non-6 GHz radios collocated with a fourth set of 6 GHz radios that consider client devices of the first non-6 GHz radio to be near-neighbors;
- based on the identifying of the first, second, third, and fourth sets of non-6 GHz radios, creating an ordered near-neighbor 6 GHz radios list ranking 6 GHz radios in the RF zone for the first non-6 GHz radio;
- and
- advertising (disseminating), in accordance with the ordered near-neighbor 6 GHz radios list, a 6 GHz radio in the RF zone in at least one of a discovery beacon and probe response of the first non-6 GHz radio.
