Definition Edit

Dynamic Frequency Selection (DFS) is a

[s]ystem by which transmitters and receivers can autonomously switch to different frequencies within a band to improve transmission and minimize interference to other users. The NTIA and DoD worked with industry to develop DFS technology that allows 5.8 GHz Wi­Fi devices to detect and avoid military radars.[1]
