DFS (Dynamic Frequency Selection) is a dynamic frequency selection protocol used in 5 GHz wireless networks to avoid interference with radar systems. DFS frequencies are those used to avoid interference with radar systems and are specific to each country.
The DFS protocol is a mechanism that allows wireless devices to detect and avoid interference with radar systems operating in the same frequency bands. It works by detecting radar signals in a specific frequency band and transmitting a channel clearing signal so that wireless devices stop using that frequency band.
In summary, DFS frequencies are those frequencies that are used in 5 GHz wireless networks to avoid interference with radar systems, through the use of a dynamic frequency selection (DFS) protocol and are specific to each country.
Remember: DFS channels vary by country.
