Maximum Power Levels and Antenna Gains
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-2 indicates the maximum
power levels and antenna gains allowed for each IEEE 802.11g regulatory domain.
Note To meet regulatory restrictions, the external antenna bridge unit and the external antenna must be
professionally installed. The network administration or other IT professional responsible for installing and
configuring the unit is a suitable professional installer. Following installation, access to the unit should be
password protected by the network administrator to maintain regulatory compliance.
