Antenna Gain Set the antenna between 0.00 - 30.00 dBm. The access point's Power
Management Antenna Configuration File (PMACF) automatically configures
the access point's radio transmit power based on the antenna type, its antenna
gain (provided here) and the deployed country's regulatory domain restrictions.
Once provided, the access point calculates the power range. Antenna gain
relates the intensity of an antenna in a given direction to the intensity that
would be produced ideally by an antenna that radiates equally in all directions
(isotropically), and has no losses. Although the gain of an antenna is directly
related to its directivity, its gain is a measure that takes into account the
efficiency of the antenna as well as its directional capabilities. Motorola
Solutions recommends that only a professional installer set the antenna gain.
The default value is 0.00.
Antenna Mode Set the number of transmit and receive antennas on the access point. 1x1 is
used for transmissions over just the single "A" antenna. 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 Select the radio button to enable the radio to have antenna diversity for
Diversity transmit frames at non 802.11n data rates. This setting is disabled by default.
Wireless Client Select the radio button to manually set the radio's transmission power (in dBm)
Power to connected clients. The setting is disabled by default.
Dynamic Chain Select the radio button for the radio to dynamically change the number of
Selection transmit chains. This option is enabled by default.
Rate Once the radio band is provided, the drop-down menu populates with rate
options depending on the 802.11b, 802.11a or 802.11n band utilized. If the
radio band is set to Sensor, the Rates screen is unavailable, 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 GHz is selected as the radio band, select separate 802.11a
and 802.11n rates, then define how they are used together.
If dedicating the radio to either 2.4 or 5 Ghz support, a Custom Rates option is
available to set a modulation and coding scheme (MCS) in respect to the
radio's channel width and guard interval. A MCS defines (based on RF channel
conditions) an optimal combination of 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). If Basic is
selected within the 802.11n Rates field, the MCS0-7 option is auto selected as
a Supported rate and that option is greyed out. If Basic is not selected, any
combination of MCS0-7, MCS8-15 and MCS16-23 can be supported, including
a case where MCS0-7 and MCS16-23 are selected and not MCS8-15. The
MCS0-7 and MCS8-15 options are available to each support access point.
However, the MCS16-23 option is only available to AP8132 model access
points and its ability to provide 3x3x3 MIMO support.
