cwrAntennaGain
Module: CISCO-WIRELESS-IF-MIB
OID (symbolic): CISCO-WIRELESS-IF-MIB::cwrAntennaGain
OID (numeric): 1.3.6.1.4.1.9.9.136.1.10.1.1.6
Node type: OBJECT-TYPE
Type: Integer32
Access: read-write
Description: This object represents the gain of this antenna.
What is cwrAntennaGain?
A read-write Integer32 (0..60 dBi) recording the gain of the antenna attached to this radio. Antenna gain feeds into link-budget and effective radiated power calculations, so an incorrect value here could cause the device or NMS to miscalculate whether a link has adequate margin. For example, swapping a 30 dBi dish for a higher-gain 38 dBi dish on a long-haul link would require updating cwrAntennaGain to keep any downstream power-budget calculations accurate.
