NOTE
Brocade Mobility 7131 Access Point, Brocade Mobility 1220 Access Point, Brocade Mobility 1220
Access Point, Brocade Mobility 1240 Access Point can support up to 256 client connections to a
single access point radio. Brocade Mobility 6511 Access Point (both single radio models) can
support up to 128 client connections to a single radio.
Antenna Mode Set the number of transmit and receive antennas on the access point. 1x1 is used for
transmissions over just a single “A” antenna, 1x3 is used for transmissions over the “A” antenna
and all three antennas for receiving. 2x2 is used for transmissions and receipts over two antennas
for dual antenna models. The default setting is dynamic based on the access point model deployed
and its transmit power settings.
Enable Antenna Diversity Select this option for the radio to dynamically change the number of transmit chains. This option is
enabled by default.
Wireless Client Power Select this option to enable a spinner control for client radio power transmissions in dBm. The
available range is 0 - 20 dBm.
Dynamic Chain Selection Select this option to allow the access point radio to dynamically change the number of transmit
chains. This setting is disabled by default. The radio uses a single chain/antenna for frames at non
802.11n data rates.
Data Rate Once the radio band is provided, the Rate drop-down menu populates with rate options depending
on the 2.4 or 5.0 GHz band selected. If the radio band is set to Sensor or Detector, the Data Rates
drop-down menu is not enabled, as the rates are fixed and not user configurable. If 2.4 GHz is
selected as the radio band, select separate 802.11b, 802.11g and 802.11n rates and define how
they are used in combination. If 5.0 GHz is selected as the radio band, select separate 802.11a
and 802.11n rates define how they are used together. When using 802.11n (in either the 2.4 or 5.0
GHz band), Set a MCS (modulation and coding scheme) in respect to the radio’s channel width and
guard interval. A MCS defines (based on RF channel conditions) an optimal combination of 8 data
rates, bonded channels, multiple spatial streams, different guard intervals and modulation types.
Clients can associate as long as they support basic MCS (as well as non-11n basic rates).
For more information on 802.11n MCS rates, see MCS Data Rates on page 5-103.
Radio Placement Use the drop-down menu to specify whether the radio is located Indoors or Outdoors. The
placement should depend on the selected country of operation and its regulatory domain
requirements for radio emissions. The default setting is Indoors.
Max Clients Use the spinner control to set the maximum permissible client connections for this radio. Set a
value from 0 - 256. Brocade Mobility 1220 Access Point, Brocade Mobility 1220 Access PointM,
Brocade Mobility 1240 Access Point, Brocade Mobility 7131 Access Point can support up to 256
clients per access point or radio. Brocade Mobility 6511 Access Point can support up to 128 clients
per access point or radio.
Rate Selection Methods Use the drop-down menu to specify the algorithm to use for rate selection. Select Standard to use
the standard rate selection algorithm. Select Opportunistic to use the Opportunistic rate selection
algorithm.
