What is the FCC regulation for the maximum equivalent isotropically radiated power (EIRP) from a point-to-multipoint WLAN antenna?

Explanation:
EIRP, or effective isotropic radiated power, is the total power radiated in a given direction from an antenna, combining the transmitter output with the antenna’s gain. For unlicensed WLAN in the 2.4 GHz band, FCC Part 15 sets a maximum EIRP of 36 dBm, which is 4 watts. That means the combined effect of the transmitter power and antenna gain can’t exceed 4 W in any direction for point-to-multipoint WLAN operations. If you use a higher-gain antenna, you must reduce the transmitter power accordingly to stay at or below this 4 W limit.
