Gain of antenna in dBi = 10*log(G).
The regulations require that the power used for the calculations is the maximum power in the transmit burst
subject to allowance for source-based time-averaging.
If there are no EIRP limits in the country of deployment, use the distance calculations for FCC 5.8 GHz for all
frequency bands.
