Wherein, a signal strength value of 60dbm to 80dbm indicates that the signal is normal, and a signal strength value of 90dbm to 80dbm indicates that the signal is very poor.

As for setting scoring rules based on channel congestion degree, setting scoring rules based on channel load capacity, and setting scoring rules based on available time, all can be set in advance.
