Appendix D Channels and Antenna Settings

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.
