Maximum Power Levels and Antenna Gains
IEEE 802.11a (5-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 A-6 indicates the maximum
power levels allowed with the Cisco integrated antenna for each IEEE 802.11a regulatory domain.
