Airmux-200 5.4 GHz ETSI Version
In accordance with ETSI, unlicensed wireless data equipment is not allowed to
interrupt radar services. Therefore, if Airmux-200 detects Radar interference it
automatically changes the frequency channel. This feature is termed Dynamic
Frequency Selection (DFS). According to the standard, a channel with active
Radar is prohibited from use for 30 minutes. Before any transmission,
Airmux-200 probes a channel for Radar signals for a period of 60 seconds.
In the 5.4 GHz ETSI version, the Automatic Channel Selection is selected by
default and a minimum of two channels must be defined as available.
