DFS Testing and Compliance Management
As the 5 GHz band has been increasingly used by manufacturers of wireless devices for a wide variety of different applications (most notably WLAN devices) there have been growing concerns over the functionality of military or weather radar systems that operate in this same portion of the radio frequency spectrum. To address these concerns the DFS requirements were established. The requirements have been published in the relevant rule parts for BRAN (Broadband Radio Access Networks)/ RLAN (Radio Local Area Network) respectively UNII (Unlicensed National Information Infrastructure) devices:
- Europe (ETSI EN 301 893)
- US (Title 47, §15.407)
- Canada (RSS-247)
- Japan (Article 2 Paragraph 1 of Item 19-3-1/19-3-2)
Any device operating in the above mentioned frequency bands have to meet the DFS requirements as stated in the relevant rules of the target markets. Devices shall not start operating on a frequency unless this frequency has been scanned and identified to be available respectively not in use by a radar system. Furthermore used frequencies must continuously be scanned for radar signal patterns during normal operation. DFS detects radar interference and moves to another “available” frequency.
