or an SSID that would require 6 GHz capability.
Preferred Scanning Channels
The 6 GHz frequency band introduces 59 more 20 MHz channels. Due to this large number of channels, the standard
implements a new efficient process for clients to discover nearby access points. This is called Preferred Scanning
Channels (PSC). PSCs are a set of 20-MHz channels that are spaced every 80 MHz. In order to support the PSC-based
clients and effectively onboard the clients in the least possible time, the 6 GHz channel selection in the RF profile for
MR57 Auto RF configuration will be restricted to a set of PSC-capable channels.
The list of the PSC channels is indicated above in green. Auto RF will choose a channel that is a PSC-supported
channel for 20, 40, 80, and 160 MHz frequencies.
Note: When disabling a channel that is being used by Auto Channel configuration settings, the system will make sure to
disable all 80 MHz of the closest PSC channel.
Warning: Please make sure to assign a PSC-supported channel when allocating a channel manually. There could be
substantially delayed in client connecting to the Access Point if a non-PSC supported channel is selected during manual
allocation
