-In many countries, operating WiFi devices in the 5GHz band requires radar detection and DFS ([[http://​wifi-insider.com/​wlan/​dfs.htm|explanation)]].

More technical details of the Linux implementation can be found [[http://​wireless.kernel.org/​en/​developers/​DFS|here]]. 
  
 DFS works roughly as follows in Linux: The driver (e.g. ath9k) detects radar pulses and reports this to nl80211 where the information is processed. If a series of pulses matches one of the defined radar patterns, this will be reported to user space application (hostapd) which in turn reacts by switching to another channel. DFS works roughly as follows in Linux: The driver (e.g. ath9k) detects radar pulses and reports this to nl80211 where the information is processed. If a series of pulses matches one of the defined radar patterns, this will be reported to user space application (hostapd) which in turn reacts by switching to another channel.
  
-As of July 2014, DFS and radar detection are supported ​in OpenWRT trunk (Barrier ​Braker). Both features are not supported in currect stable release ​(Attitude Adjustment).+[[https://​lists.openwrt.org/​pipermail/​openwrt-devel/​2014-July/​026497.html|As of July 2014]], DFS and radar detection are supported ​from OpenWrt 14.07 (Barrier ​Breakeron, 12.09 (Attitude Adjustment) ​and earlier do not support this. By default, however, OpenWrt uses [[http://​wiki.openwrt.org/​doc/​devel/​packages/​wpad-mini|wpad-mini]],​ which **does not support DFS**. To use DFS, rebuild your image (using the [[http://​wiki.openwrt.org/​doc/​howto/​obtain.firmware.generate|image generator]] or the [[http://​wiki.openwrt.org/​about/​toolchain|buildroot]]),​ include both hostapd and wpa-supplicant as static packages, and remove wpad-mini.
  
 Currently, many members of the mac80211 family of WiFi drivers do support radar detection. ​ DFS is mandatory for most channels in the 5GHz band (exception: indoor-only channels) in many countries. ​ If you define a channel in your wireless config that requires DFS according to your country regulations,​ the 5GHz radio device won't start up if you run an OpenWRT version that lacks DFS support or if your system is not configured properly. Currently, many members of the mac80211 family of WiFi drivers do support radar detection. ​ DFS is mandatory for most channels in the 5GHz band (exception: indoor-only channels) in many countries. ​ If you define a channel in your wireless config that requires DFS according to your country regulations,​ the 5GHz radio device won't start up if you run an OpenWRT version that lacks DFS support or if your system is not configured properly.
