I need to adjust an Ubiquity XR2 TxPower from the original 28dBm to about 20dBm in a RB600.
I know the adjustments in the wireless interface can go from 1dBm up to 26dBm but they are relative and I think the default (17dBm) is the card's factory default resulting in 28dBm from the card, am I right?
If so, where should I put the TxPower to obtain the desired 20dBm output? Is there any reference table around?
Any hint would be of great help.
