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. Table E-3indicates the maximum EIRP supported for all regulatory domains for each 5 GHz IEEE 802.11a data rate.
