NOTE
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.
At 5.4 GHz and EU 5.8 GHz, the products are generally limited to a fixed
EIRP which can be achieved with the Integrated Antenna. The calculations
above assume that the maximum EIRP allowed by the regulations is being
transmitted.
NOTE
If there are no EIRP limits in the country of deployment, use the distance
calculations for FCC 5.8 GHz for all frequency bands.
At FCC 5.8 GHz, for antennas between 0.6m (2ft) and 1.8m (6ft), alter the
distance proportionally to the antenna gain.
At 2.5 GHz, for antennas between 1.2m (4ft) and 3.6m (12ft) the safe
distance is increased to between 0.8m (2.6 ft) and 2.4m (7.8 ft).
