Dynamic Frequency Selection (DFS)

When implemented on a Wi-Fi device, Dynamic Frequency Selection (DFS) allows for additional 5GHz channels to be used in the absence of other nearby emitters using that frequency (typically radar systems). The FCC database is useful for determining whether a device supports DFS. Results will show a frequency range of 5260.0 MHz to 5320.0 MHz (U-NII-2). DFS support is sometimes added through a firmware update with an associated Class II Permissive Change Request at the FCC.

See SmallNetBuilder's Wi-Fi Dynamic Frequency Selection (DFS) FAQ for a more detailed explanation.

Below are lists of devices that have been flagged as having DFS.
