8.4 FCC Emission Regulations
The following charts show the maximum emissions allowed for the FCC in the
United States. These data should only be considered guidelines. Consult official
FCC documents for the latest official regulations.
In the 2.4 GHz band, the maximum Equivalent Isotropically Radiated Power
(EIRP) is 4W for multipoint links: that is, radios with omnidirectional antennas.
Point-to-Point links using directional antennas are allowed higher EIRP.

The FCC states that for every 1 dBi power reduction in the radio’s transmitter
output, the antenna gain may be increased by 3 dB.
