rx-sensitivity-reduction
Allows you to set the selected radio's receive sensitivity reduction threshold level.
This threshold determines the RSSI (in dBm) at which the radio acknowledges the SOP
(Start of Packet) frames received from clients and begins to
demodulate and decode the packets.
In highly dense environments, or single-channel networks, having two or more radios
sharing a channel, CCI (co-channel interference) adversely impacts
network performance. By setting this threshold, you can control the radio‘s receive
sensitivity to interference and noise, thereby reducing the impact of CCI. You are
basically configuring the AP to not decode packets that have a signal strength below
the specified threshold level.
The available rx-sensitivity-reduction threshold levels are: high, low, medium, and None. Refer to the

|
rx-sensitivity-reduction [auto|high|low|medium]
|
Sets the selected radio's receive sensitivity reduction threshold
level. The options are:
-
high – Sets the threshold level as high. By setting
the threshold at high, you are forcing the radio to
ignore all traffic having a signal strength below
the high threshold value. This results in fewer
traffic interruptions due to collision and Wi-Fi
interference.
-
low – Sets the threshold level as low.
-
medium – Sets the threshold level as medium.
-
none – Does not set a threshold. This option is
applicable for networks having minimal to no
CCI.
Note:
The default setting is None.
