Maximum Power Levels and Antenna Gains
IEEE 802.11a (5-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-7
indicates the maximum
power levels allowed with RM20A radio module for each IEEE 802.11a regulatory domain.
Note
The maximum power level for Chile is 20 mW. When operating in Chile, you must ensure that your
access point Transmitter Power setting never exceeds 20 mW.
