Channels and Power Levels

This appendix lists the IEEE 802.11b/g (2.4-GHz) and the IEEE 802.11a (5-GHz) channels and maximum power levels supported by the world's regulatory domains.

The following topic is covered in this appendix:

• Channels and Maximum Power Levels

Channels and Maximum Power Levels

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 D-1 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-2 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:
