Introduction
• In July of this year the Wi-Fi Alliance Regulatory Task Group of
the Spectrum and Regulatory Committee undertook a project to
create a document to better educate its membership about DFS
• Dynamic Frequency Selection (DFS), as specified by WRC-03 as a
requirement in the 5250 – 5350 and 5470 – 5725 MHz bands
enables RLANs to share these bands with radar
• The mechanism has been successful when sharing the band with
the specified radars
• Recent test have shown that the DFS specification did not
comprehend narrow pulse (0.5 – 1.0uS) or staggered PRF radars
• Changes are in process in many regulatory domains
• The document aims to foster understanding of the radars and the
interference mitigation methods
• The WFA Board of Directors approved the document in October,
and approved its public release’ presented here to IEEE 802.18
