MSM7xx Controllers Configuration Guide v6.4.0

Distance between APs
Not available in Monitor or Sensor modes.
Use this parameter to adjust the receiver sensitivity of the AP only if you have a very dense
deployment where many APs are close together. In all other cases, use the default setting of Large.
If you have installed multiple APs, reducing the receiver sensitivity helps to keep clients with low
signal quality from connecting, thereby increasing the probability that client stations connect with
the nearest AP.
Available settings
• Large: Accepts all clients.
• Medium: Accepts clients with an RSSI greater than 15 dB.
• Small: Accepts clients with an RSSI greater than 20 dB.
NOTE: RSSI (Received Signal Strength Indication) is the difference between the amount of noise
in an environment and the wireless signal strength. It is expressed in decibels (dB). The higher the
number the stronger the signal.
Beacon interval
Not available in Monitor or Sensor modes.
Sets the number of time units (TUs) that the AP waits between transmissions of the wireless beacon.
One TU equals 1024 microseconds. The default interval is 100 TU, which is equal to 102.4
milliseconds. Supported range is from 20 to 500 TU.
Multicast Tx rate
Not available in Monitor or Sensor modes.
Use this parameter to set the transmit rate for multicast and broadcast traffic. This is a fixed rate,
which means that if a station is too far away to receive traffic at this rate, the multicast is not seen
by the station.
Traffic shaping
Not available in Monitor or Sensor modes.
(Only available on the MSM410, HP 425, MSM430, MSM460, MSM466, and MSM466-R.)
Use this parameter to define how wireless air time is shared between client stations. Traffic shaping
applies to all client stations connected to all VSCs that use this radio.
• Disabled: Traffic shaping is off.
• Airtime fairness: The AP attempts to provide each client with an equal share of wireless time.
Both transmit and receive times are considered. Airtime fairness is QoS-aware.
Transmit power control
Not available in Monitor or Sensor modes.
Use these parameters to control the transmission power of the wireless radio.
Adjustments to the transmission power may be required for two reasons. First, when using an
optional external antenna, it may be necessary to reduce power levels to remain in compliance
with local regulations. Second, it may be necessary to reduce power levels to avoid interference
between APs and other radio devices.
