The 802.11 workgroup currently documents use in five distinct frequency ranges: 2.4 GHz, 3.6 GHz, 4.9 GHz, 5 GHz, and 5.9 GHz bands.〔(【引用サイトリンク】title=IEEE 802.11-2007: Wireless LAN Medium Access Control (MAC) and Physical Layer (PHY) specifications )〕 Each range is divided into a multitude of channels.

In some countries, such as the United States, licensed Amateur Radio operators may use some of the channels at much higher power for long distance wireless access. == 2.4 GHz (802.11b/g/n) ==
