Channels and Maximum Power Levels
IEEE 802.11b/g (2.4-GHz Band) on Dual Radio Models
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-2 indicates the channel
identifiers, channel center frequencies, and maximum power levels for each channel allowed by the
regulatory domains:
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-3 indicates the channel identifiers, channel center frequencies, and maximum power levels for
each IEEE 802.11a 20-MHz-wide channel allowed by the regulatory domains:
