Dynamic Frequency Selection (DFS)

Dynamic Frequency Selection (DFS) is a technology used in wireless networks to automatically select and switch to less congested or interference-free radio channels, especially in the 5 GHz band. It helps prevent interference with radar systems and other critical communications by monitoring the airwaves. When radar signals are detected, the network quickly moves to a different channel to avoid interference, ensuring reliable Wi-Fi performance and compliance with regulations. Essentially, DFS allows wireless devices to adapt dynamically to their environment for better connectivity and less disruption.
