General Regulatory Notices
Dynamic Frequency Selection
Dynamic Frequency Selection (DFS) may be required by regional legislation in some
frequency bands in order 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.
Antennas
The following Tables list antennas recommended for use with the i-Series radios. The
EX-4.9i may use any antenna. In some countries, antennas exceeding a certain level of
gain may be unlawful. Refer to RF Output Power Setting in this Appendix for details on
regulatory limits.
