Product and Software: This article applies to Aruba Instant Access Points (IAP's) with external antenna running Aruba InstantOS.
Follow steps to configure antenna gain for IAP with external antenna:
Login to the Instant WebUI.
In the WebUI, navigate to the Access Point tab, select the specific access point and then click Edit.
In the Edit Access Point window, select External Antenna tab to configure the antenna gain value.
This option is available only for access points (IAP-134/92) with external antenna support.
4. Enter the antenna gain values (dBm) for 2.4GHz and 5GHz bands and click OK
Note: Additional attenuation between the device and antenna may have to be measured or calculated
Below images should help more on the navigation in GUI:
The following formula can be used to calculate the EIRPlimit related RF power based on selected antennas
EIRP = Tx RF Power (dBm) +GA (dB) - FL (dB)
