In order to be able to quickly change channel if radar is detected during operations, the device determines a minimum number of alternative channels that are expected to be vacant (also see 2.23.20.8.27 DFS-Rescan-Num-Channels.
- Yes
- Within a period of 60 seconds, the device gathers information about all of the channels by jumping between them at 500ms intervals. If the device subsequently detects a radar during its operations, it immediately switches to another channel.
