Linea 8: Linea 8:
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/.
Linea 10: Linea 10:
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 ==
