Maximum Power Levels
IEEE 802.11b (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-3 indicates the maximum
power levels allowed with the Cisco integrated antenna for each IEEE 802.11b regulatory domain.
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-4 indicates the maximum
power levels allowed with the Cisco integrated antenna for each IEEE 802.11g regulatory domain.
