With this most recent release of the access point firmware, a Power Management Antenna
Configuration File (PMACF) has been added to the access point firmware that automatically
configures the access point’s radio transmit power based on the antenna type deployed, its
supported gain and the deployed country’s regulatory domain restrictions. The antenna type is
defined using the access point’s CLI by assigning a numerical code representing a particular type
(or category) of antenna. The following are the numerical codes representing available antenna
types: 0-Default antenna, 1-Dual band antenna, 2-Omni antenna, 3-Yagi antenna, 4-Embedded
antenna,

5-Panel antenna, 6-Patch antenna and 7-Sector antenna. The antenna gain can be defined using
either the access point’s CLI, applet or SNMP interfaces.

Once the antenna type and gain are provided, the access point calculates the power range. The
PMACF contains transmit power data for each Brocade approved antenna type. Professional
installers enter the antenna type (using the access point’s CLI interface), and the access point
firmware calculates the transmit power automatically. Therefore, professional installers no longer
need to second guess whether the power is over the maximum allowed level.

NOTE

The antenna type and antenna gain values are maintained by the access point after a power cycle,
and are available in imported or exported configurations.

For information on specifying the antenna type and gain for the 2.4 and 5 GHz radios using the
access point CLI, see br7131>admin(network.wireless.radio.802-11n[2.4 GHz])>set for the access
point’s 2.4 GHz radio and br7131>admin(network.wireless.radio.802-11n[5.0 GHz])>set for the
access point’s 5 GHz radio.

For information on defining the antenna gain using the access point’s GUI applet, see Configuring
the 802.11a/n or 802.11b/g/n Radio on page 5-167 and Configuring the 802.11a/n or
802.11b/g/n Radio on page 5-167.
