The Digi-Wave™ system is a digital spread-spectrum (DSS), simultaneous two-way wireless listening system. Using its frequency-hopping algorithm, it avoids interference and is a very secure method of communication.
The Williams AV DWS PCS 3 400 RCH Digi-Wave Personal Communication System includes the DLT 400 transceiver and the DLR 400 RCH receiver which allows users to listen and talk to one another wirelessly in a variety of scenarios.
