DFS is the focus of much debate in the wireless industry. Here’s why it’s a crucial requirement with the arrival of 802.11ac devices.

 Dynamic Frequency Selection (DFS) has been a topic of debate among wireless vendors and implementers alike. DFS has been a consideration since the first 5GHz Wi-Fi standard, 802.11a. But now, the wider bandwidth channels used in 802.11ac compound the problems introduced by DFS.

In a three-part series, I’ll examine DFS and the challenges it poses for wireless vendors and enterprises implementing 802.11ac. In this post, I’ll explain DFS and its critical purpose in protecting mission-critical systems sensitive to RF interference from Wi-Fi and similar devices.
