State one of the channel parameter of current non-radar busy channel, and if it exists, then follow the steps S213.
The nearest historical channel parameter refers to working frequency range of the wireless access point 300 before carrying out Emergency avoidance.
When being current non-radar busy channel there are working frequency range of the wireless access point 300 before Emergency avoidance under nonredundancy state
One of them when, show that the radar occupancy situation on the former working frequency range of the wireless access point 300 no longer exists.
And step S213, by the channel parameter of the wireless access point 300 of the nonredundancy state be regulated to again it is described most
Nearly historical channel parameter.
