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 scan time, a client device usually scans the PSC channels first and, if no APs are found, then scans all the channels. Deploying the APs on the PSC channels improves the probability for the AP to be discovered faster. However, note that collocated APs use the Reduced Neighbor Report to assist with discovery when the client device scans the 2.4 GHz or 5 GHz bands. Please refer to the RNR section below.
