SoftRadio RIUs can be, and are deployed in a range of custom applications. For example multiple 4-wire RIUs are used to connect to transmitter and receiver assemblies in a test-bed. Other installations inlcude replacing leased lines for base-stations (2- & 4-wire RIUs) and voice-only applications such as the monitoring of remote Airband radios. Pre-configured Interconnect Kits (RIU/radio interconnect) are available for a range of radio models and manufacturers.
