Maximum Power Levels and Antenna Gains

Maximum Power Levels and Antenna Gains

IEEE 802.11a

An improper combination of power level and antenna gain can result in equivalent isotropic radiated
power (EIRP) above the amount allowed per regulatory domain.
power levels and antenna gains allowed for each IEEE 802.11a regulatory domain.
