a-external-antenna a-external-antenna Description This command configures external antenna connectors for a W-IAP. Syntax Parameter Description Range Configures the antenna gain. You can configure a gain value in dBi for the following types of antenna: l Dipole/Omni l Panel l Sector Diploe/Omni - 6 Panel -14 Sector - 14 Usage Guidelines 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 antenna before configuring the antenna gain. To know if your AP device supports external antenna connectors, see the Install Guide that is shipped along with the AP 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: Table 8: Formula Variable Definitions 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 For information on antenna gain recommended by the manufacturer, see dell.com/support. Example The following example configures external antenna connectors for the W-IAP with the 5 GHz radio band. 16 | a-external-antenna Dell Networking W-Series Instant 6.4.3.1-4.2.0.0 | CLI Reference Guide
