Configuring External Antenna
If your W-IAP has external antenna connectors, you need to configure the transmit power of the system. The
configuration must ensure that the system’s Equivalent Isotropically Radiated Power (EIRP) is in compliance
with the limit specified by the regulatory authority of the country in which the W-IAP is deployed. You can also
measure or calculate additional attenuation between the device and the antenna before configuring the
antenna gain. To know if your W-IAP device supports external antenna connectors, refer to the Dell Networking
W-Series Instant Installation Guide that is shipped along with the W-IAP device.
EIRP and Antenna Gain
The following formula can be used to calculate the EIRP-limit-related RF power based on selected antennas
(antenna gain) and feeder (Coaxial Cable loss):
EIRP = Tx RF Power (dBm) + GA (dB) - FL (dB)
The following table describes this formula:
Formula Element Description
EIRP Limit specific for each country of deployment
Tx RF Power RF power measured at RF connector of the unit
GA Antenna gain
FL Feeder loss
Table 18: Formula Variable Definitions
Example
For example, the maximum gain that can be configured on a W-IAP with AP-ANT-1F dual-band and omni-
directional antenna is as follows:
Frequency Band
Gain (dBi)
2.4–2.5 GHz 2.0 dBi
4.9–5.875 GHz 5.0 dBi
Table 19: Maximum Antenna Gains
For information on antenna gain recommended by the manufacturer, see dell.com/support.
Configuring Antenna Gain
You can configure antenna gain for W-IAPs with external connectors by using the Instant UI or the CLI.
In the Instant UI
To configure the antenna gain value:
1. Navigate to the Access Points tab, select the W-IAP to configure, and then click edit.
2. In the Edit Access Point window, select External Antenna to configure the antenna gain value. This
option is available only for access points that support external antennas,
3. Enter the antenna gain values in dBm for the 2.4 GHz and 5 GHz bands.
