Dynamic frequency selection
text:
Dynamic Frequency Selection (DFS) is a channel allocation scheme specified for wireless LANs, commonly known as Wi-Fi. It is designed to prevent electromagnetic interference by avoiding co-channel operation with systems that predated Wi-Fi, such as military radar, satellite communication, and weather radar, and also to provide on aggregate a near-uniform loading of the spectrum. It was standardized in 2003 as part of IEEE 802.11h.
