Maximum Power Levels Allowed in Some Regulatory Domains
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 9-4 indicates the maximum power levels
allowed with an 8 dBi external antenna in the –A and –N regulatory domains.
Caution To avoid exceeding maximum conducted power levels in the –A , –N, and –E regulatory domains when
using an 8 dBi antennas, you must manually set the access point output power level to not exceed the
value shown in Table 9-4 and Table 9-5.
Note In Table 9-4 and Table 9-5, the operating data rates (in Mbps) are shown in the CCK and OFDM table
cells. For example: OFDM 9-24 indicates 9 to 24Mbps data rates and All OFDM indicates 6 to 54 Mbps
data rates.
