Channels and Maximum Power Levels
Table 7-7 indicates the channel identifiers, channel center frequencies, and maximum power levels for
each channel allowed by the –P regulatory domain for a 2.4-GHz radio with up to 10-dBi antennas.
5 GHz Band (Draft IEEE 802.11n Version 2.0)
An improper combination of power level and antenna gain can result in equivalent isotropic radiated
power (EIRP) above the amount allowed per regulatory domain.
