Countries around the world are requiring that 5 GHz Wireless LAN (WLAN) devices support the latest Dynamic Frequency Selection (DFS) standards. DFS prevents interference with military and civilian radars by moving WLAN transmissions out of the channels used by the radars when radars are present. Because the affected spectrum varies by country, WLAN chipsets must implement a highly detailed and adaptable compliance mechanism. DFS requirements are crucial for new-generation WLANs based on the IEEE 802.11n standard. To a large extent, 802.11n was devised to provide the higher throughput capacity needed for more robust WiFi applications, such as Voice over IP (VoIP) and multiple, simultaneous, real-time, high-definition video streams.
