The PSC channels play an important role in discovering the Access Points in the 6 GHz band. When scanning the 6 GHz band, to optimize for scan time a client device usually scans first the PSC channels and if no APs are found, then it scans all the channels. Deploying the APs on the PSC channels improves the probability for the AP to be discovered faster. However, note that the collocated APs use the Reduced Neighbor Report to assist with being discovered while the client device scans the 2.4 GHz or the 5 GHz bands. Please refer to the RNR section below.
