Question: How do I increase the power level of specific AP and AP group?
Product and Software: This article applies to all Aruba controllers and APs and ArubaOS 3.x.x.x.
By default, the AP transmits power up to 9 dbm. If you increase the transmit power, the coverage is increased. Note that changing the transmit power may at times cause co-channel and adjacent channel interference between the access points.
You can use the webUI or CLI to increase the power level for an AP or AP group.
Using the WebUI
To increase the power level for the specific AP, follow these steps:
1) Navigate to Configuration > Wireless > AP configuration.
2) Click the tab for the specific AP and select the AP name or enter the name of AP. Click Add.
3) After the AP is added, click Edit.
4) Expand RF Management and click the 802.11g radio profile.
5) Click the Adaptive Radio Management profile and create a new profile for ARM.
6) In that profile, disable the Assignment option and uncheck the scanning option.
7) Increase the Minimum EIRP/Maximum EIRP level to alter the power transmit settings of the AP.
Note: that the AP cannot transmit beyond the EIRP set in hardware (specified in the data sheet for the AP) and also the transmit power on the AP is limited by the FCC regulations for that particular area.
8) Apply the settings.
9) Change the 802.11g radio profile from "inherited"to the profile you created and click Apply.
To increase the power level for the AP group, follow these steps:
1) Navigate to Configuration > Wireless > AP configuration
2) Click Edit for the group for you want to increase the power level.
3) Expand RF management and select the Adaptive Radio Management profile.
4) Increase the minimum/maximum ERP level and click Apply.
Using the CLI
To increase the power level of the specific AP, issue these commands:
(Aruba2400) (config) #rf arm-profile <arm profilexxx>
(Aruba2400) (Adaptive Radio Management (ARM) profile "arm profilexxx") #
(Aruba2400) (Adaptive Radio Management (ARM) profile "arm profilexxx") #min-tx-power 24
(Aruba2400) (config) #rf dot11g-radio-profile < rf dot 11g profilexxx >
(Aruba2400) (802.11g radio profile " rf dot 11g profilexxx") #arm-profile <arm profilexxx>
(Aruba2400) (config) #ap-name <ap-namexxx>
(Aruba2400) (AP name "ap-namexxx") #dot11g-radio-profile < rf dot 11g profilexxx>
To increase the power level for the AP group, issue these commands:
(Aruba2400) (config) # rf arm-profile <arm profile yyyy>
(Aruba2400) (Adaptive Radio Management (ARM) profile "arm profile yyyy") #min-tx-power 24
(Aruba2400) (config) #rf dot11g-radio-profile < rf dot 11g profileyyyy >
(Aruba2400) (802.11g radio profile " rf dot 11g profileyyyy") #arm-profile <arm profile yyyy>
