Cadia Valley Mine Upgrade of Existing Tait P25 Digital System for above and below ground communications.
RFI, working with our customer, Illawarra Communications, assisted in upgrading the existing Tait P25 Digital System. This communications system proved to be pivotal in the new developments in above and below ground communications. The upgraded communications system deployed incorporated eight new channels and the change of four old legacy channels to P25 utilising the Tait TB9100 Base.
RFI supplied the antennas, Bi-Directional Amplifiers (BDA) and the multicoupling and backwards compatibility with the existing Tait TB9100 repeater base station. The Cadia work force has over 1500 personnel on-site every day and deploys heavy vehicles, light vehicles, rescue chambers, operation areas and a vast man machinery development system above and below ground. This requires a control centre with reliable communications. RFI’s contribution to the project was our experience in the multicoupling of low PIM P25 digital systems to enhance and maintain reliable communications whether the radio operator is on a hand held radio underground, or the radio operating out of a heavy vehicle. The Cadia Radio Communications Network operates 24 hours a day and encompasses the entire Cadia Valley Operations, including the Open Pit, Ridgeway and Ridgeway Deeps Underground.
