3. During its operation, the End Point B scans for radar continuously and after detecting the radar, it sends a message to
the End Point A indicating radar detection on that current channel and blacklists that channel for Non Occupancy
Period (NOP). The default NOP is 30 minutes.
4. End Point B restarts scanning for the End Point A as mentioned above in Step 1.
5. End Point B never scans any blacklisted channels.
6. End Point B de-blacklists the blacklisted channel only after Non Occupancy Period.
For detailed information on DFS enabled countries, refer to Frequency Domains and Channels.
End Point A’s behavior on receiving RADAR event message from End Point B
As soon as End Point A receives RADAR event message from End Point B, End Point A de-registers that End Point B
immediately and blacklists that channel for NOP and triggers the channel switch in case of Point-To-Point link.
In case of Point-To-MultiPoint also, End Point A shall de-register the End Point B, if it receives RADAR event message from End
Point B.
