Dynamic Frequency Selection
Dynamic Frequency Selection (DFS) may be required by regional legislation in some frequency bands
to avoid causing interference to radar systems. Prior to the start of any transmission, the device
equipped with DFS monitors the spectrum and is not permitted to transmit on a part of the spectrum
that is already in use for radar transmissions for a period of 30 minutes. During operation of the device,
the spectrum is continually monitored by the DFS to detect if radar begins transmission on a frequency
that is being used by the device to transmit on. If the DFS software detects radar, the device must move
off channel within a specified time period so that the device transmission does not interfere with the
radar transmission. The device equipped with DFS is required to stay off that part of the spectrum for a
minimum of 30 minutes, after which time the device may then check the spectrum for radar
transmissions and begin transmitting if no radar is detected.
