The following tables list the channel numbers and center frequencies used for 802.11a and 802.11b/g. Note that while all of these frequencies are in the unlicensed ISM and U-NII bands, not all channels are available in all countries. Many regions impose restrictions on output power and indoor / outdoor use on some channels. These regulations are rapidly changing, so always check your local regulations before transmitting. | We recommend these resources for learning more about the various aspects of wireless networking. For more links and resources, see our website at http://wndw.net/. |

Note that these tables show the center frequency for each channel. Channels are 22MHz wide in 802.11b/g, and 20MHz wide in 802.11a. | == Antennas and antenna design == |
