Chapter 8 Cisco Aironet 1300 Series Access Points

Maximum Power Levels and Antenna Gains

IEEE 802.11b/g (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 8-2 indicates the IEEE 802.11b/g

maximum power levels and antenna gains allowed for each regulatory domain.

Note To meet regulatory restrictions, the external antenna access point/bridge 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.
