Dynamic frequency selection is a technology that is designed to ensure that wireless devices operating in the unlicensed WLAN 5 GHz bands are able to detect when they may be interfering with military and weather radar systems and automatically switch over to another frequency where they will not cause any disturbance. These formal requirements are in effect in the USA, Canada, Europe, Japan, Australia, Korea and other markets around the world.
