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 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 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 Select the radio button for the radio to dynamically change the number of
Diversity transmit chains. This option is enabled by default.
Wireless Client Select the radio button to enable a spinner control for client radio power
Power transmissions in dBm. The available range is 0 - 20 dBm.
Dynamic Chain Select this option to allow the access point radio to dynamically change the
Selection 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.
Rate Once the radio band is provided, the Rate drop-down menu populates with rate
options depending on the 2.4 or 5 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 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 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).
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.
