Maximum Power Levels

---

This document lists the maximum power levels, and antenna gains supported by the world's regulatory domains.

IEEE 802.11g (2.4-GHz Band)

An improper combination of power level and antenna gain can result in equivalent isotropic radiated power (EIRP) that exceeds the amount allowed per regulatory domain. Table 1 indicates the maximum power levels and antenna gains allowed for each IEEE 802.11g regulatory domain.

Note To meet regulatory restrictions, the external antenna BR1300 must be professionally installed by someone such as the network administration or other IT professional. Following installation, access to the unit should be password protected by the network administrator to maintain regulatory compliance.
