MSM7xx Controllers Configuration Guide v6.4.0

MIMO uses spatial multiplexing to transport two or more data streams simultaneously on the same
channel to increase throughput. For example, under most conditions, multiplexing two streams can
result in double the throughput of a single stream.
MIMO mode 2x2 is automatically used, which means that both antennas (either internal or external)
are used to transmit and receive the spatial streams.
Antenna gain
Supported on: MSM310. MSM310-R, MSM320, MSM320-R, MSM466, MSM466-R, and HP
425 (when an external antenna is selected).
Not available in Monitor or Sensor modes.
For optimum performance, this parameter must be set to the gain of the antenna.
Max clients
Not available in Monitor or Sensor modes.
Specify the maximum number of wireless client stations that can be supported on this radio across
all VSCs.
Advanced wireless settings
Client restriction
Only available when Wireless mode supports 802.11ac or 802.11n.
Use this option to restrict access to the wireless network to specific types of wireless clients.
• 802.11n only: Only wireless clients supporting 802.11n can connect. This prevents
802.11a/b/g client stations from accessing the wireless network.
• 802.11ac only: Only wireless clients supporting 802.11ac can connect. (HP 517 only)
• 802.11ac or 802.11n only: Only wireless clients supporting 802.11ac or 802.11n can
connect. (HP 517 only).
Collect statistics for wireless clients
Not available in Monitor or Sensor modes.
When this option is enabled, the AP collects statistics for connected wireless client stations. The
statistical information can be retrieved via SNMP from the following MIBs:
TableMIB
coDeviceWirelessDetectedStationTableCOLUBRIS-DEVICE-WIRELESS-MIB.my(controlled mode)
coDot11DetectedStationTableCOLUBRIS-IEEE802DOT11.my(autonomous mode)
Tx beamforming
Supported on: MSM430, MSM460, MSM466, MSM466-R
Not available in Monitor or Sensor modes.
Tx beamforming can be used to help increase throughput by improving the quality of the signal
sent to wireless clients
When this option is enabled, APs use beamforming techniques to optimize the signal strength for
each individual wireless client station. Beamforming works by changing the characteristics of the
transmitter to create a focused beam that can be more optimally received by a wireless station.
