1. 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.
