DFS is Dynamic Frequency Selection, which is a function of using 5 GHz Wi-Fi frequencies that are generally reserved for radar, such as military radar, satellite communication, and weather radar. The DFS channels vary from country to country. The main benefit to use DFS channels is to increase the number of Wi-Fi channels. It is legally required Channel Availability Check process to prevent electromagnetic interference the 5 GHz frequency with the radar. If any radar signal detects, it will switch from DFS channel to non-DFS channel automatically(If driver have DFS support) .
The scope of this work is to integrate and validate the DFS Feature in RPI reference platforms.
