The WIPS
countermeasure is carried out by polling the channel, so how long is the
polling period for a week?
Solution: The minimum
channel switching period is 100ms, the main channel scanning time is 500ms
(that is, 5 minimum channel switching periods), and the secondary channel
scanning time is 200ms; first poll and scan all the main channels, and then
poll and scan all the secondary channels; The main channel and the secondary
channel are distinguished by the AC according to the degree of busyness. So in
general, the scanning time of 2.4G is distributed between 2.8S and 7S.
