NOTES:
• 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.
• 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).
