The operation that AP performs switching channel is sent out, that is, it is 0 time to get the switching times in 1 hour, and predetermined threshold value now is to hold
The predetermined threshold value improved after row step S32, and non-default predetermined threshold value, then the predetermined threshold value of the raising is reduced by 3 or 2%.
Need exist for explanation, step S33 execution, untill predetermined threshold value is the predetermined threshold value of acquiescence.
Therefore, the embodiment of the present application is by the way that the predetermined threshold value of raising is gradually reduced, come reduce interference value met it is pre-
Fixed condition so that the sensitivity that AP performs switching channel operation improves, so that it is guaranteed that AP provides more stable network service.
In summary, the embodiment of the present application is by the modulation to predetermined threshold value, to adjust the predetermined bar that interference value meets more
Part so that AP performs switching channel operation and is adjusted flexibly, and then ensure that AP provides more stable network service.
