2.4 GHz EIRP Rules for FCC Governed
Areas
•Point-to-Multipoint
–FCC allows increasing the gain of an antenna/cable system if
the transmitter power is reduced below 30 dBm
in a 1:1 ratio
–Reduce Transmit Power below maximum of 30 dBm by 1 dBm and
increase antenna/cable system gain by 1dBi
•Point-to-Point
–Maximum of 36 dBm EIRP
–Installations – 30 dBm maximum transmitter power with 6 dBi in
gain attributed to antenna and cable
combination
•FCC allows exceeding the 36 dBm EIRP in Point-to-Point
installations using the 3:1 rule
–Reduce Transmit Power below maximum of 30 dBm by 1 dBm and
increase antenna/cable system gain by 3 dBi
