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.
allowed for each data rate in the IEEE 802.11a regulatory domains.
