List of WLAN Channels - 5 GHz (802.11a/h/j/n)

5 GHz (802.11a/h/j/n)

Countries apply their own regulations to both the allowable channels, allowed users and maximum power levels within these frequency ranges. Consult your local authorities as these regulations may be out of date as they are subject to change at any time.

European standard EN 301 893 covers 5.15-5.725 GHz operation, and v1.7.1 is in force.

In 2007 the FCC (United States) began requiring that devices operating on 5.250–5.350 GHz and 5.470–5.725 GHz must employ dynamic frequency selection (DFS) and transmit power control (TPC) capabilities. This is to avoid interference with weather-radar and military applications. In 2010, the FCC further clarified the use of channels in the 5.470–5.725 GHz band to avoid interference with Terminal Doppler Weather Radar (TDWR) systems. This statement eliminated the use of channels 120, 124, and 128. Channels 116 and 132 may be used, so long as they are separated by more than 30 MHz (center-to-center) from a TDWR located within 35 km of the device. There are now at least five relevant KDBs about operation in 5 GHz radar bands.

Germany requires dynamic frequency selection (DFS) and transmit power control (TPC) capabilities on 5.250–5.350 GHz and 5.470–5.725 GHz as well, in addition the frequency range 5.150–5.350 GHz is only allowed for indoor use, leaving only 5.470-5.725 GHz for outdoor and indoor use.

Since this is the German implementation of EU-Rule 2005/513/EC, similar regulations must be expected throughout the European Union.

Austria adopted Decision 2005/513/EC directly into national law. The same restrictions as in Germany apply, only 5.470-5.5725 GHz is allowed to be used outdoor and indoor.

South Africa simply copied the European regulations.

Japan no longer allows 34, 38, 42, and 46 channels for connecting J52 supported old APs. Authorization to use these channels expired in May 2012.

In Brazil, the TPC use in 5,150–5,725 MHz band is optional. DFS is required only in 5,470–5,725 MHz band.

Australian DFS channels also require TPC, or the maximum allowed power is cut in half.
