"WitrynaThe purpose of DFS is to determine the carrier frequencies for the carriers in order to find an available or at least lightly loaded carrier frequency. Since around 25 frequency channels, each 20 MHz wide, are part of the 5 GHz band, and the output power is fairly low, there is a reasonably high likelihood to find unused or lightly loaded channels.
