The 5.4 GHz ETSI Version
In accordance with ETSI, unlicensed wireless data equipment is not
allowed to interrupt radar services. Therefore, if the ETSI Version
detects Radar activity, 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, WinLink™ 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.
