As shown in
, APs 1, 2 and 3 cover an area. When AP 4 joins, the default maximum neighbor
number 3 (configurable) is reached. Among all the neighbors AP 2, AP 3, and AP 4 of AP 1, the signal
strength of AP 4 is the third, so AP 4 becomes the AP that performs power detection. If AP 4 detects that
the power of AP 1 is –90 dBm, which is lower than the default power adjustment threshold –80 dBm
(configurable), AP 1 will increase its transmission power. If AP 4 detects that the power of AP 1 is –70
dBm, which is higher than the power adjustment threshold –80 dBm, AP 1 will decrease its transmission
power.
NOTE:
•
The maximum number of neighbors and the neighbor AP that performs power detection are configured
with the dot11a adjacency-factor and dot11bg adjacency-factor commands.
•
The adjusted transmission power cannot be smaller than the minimum transmission power.
Figure 58 Power reduction
As shown in
, when AP 3 fails or goes offline, the other APs increase their transmission power
to cover the signal blackhole.
