Maximum Power Levels and Antenna Gains
IEEE 802.11g (2.4-GHz Band)
An improper combination of power level and antenna gain can result in equivalent isotropic radiated
power (EIRP) above the amount allowed per regulatory domain. Table D-5 indicates the maximum
power levels and antenna gains allowed for each IEEE 802.11g regulatory domain.
