The default setting automatically optimizes the value for guard interval. If the momentary operating conditions allow, the interval will be set to the shortest possible value.
You also have the option is deactivating this mechanism to prevent the short-guard interval from being used.
Put simply, the guard interval reduces the signal distortion caused by intersymbol interference (ISI) when using signal multiplexing (OFDM).
