New Zealand Waterview Tunnel Rebroadcast and Break-In Comms System
RFI supplied the system for the rebroadcast of AM/FM radio stations and local Police, Fire and Ambulance two-way radio networks (including duplex and simplex fire-ground channels for in-tunnel incident communications). A new UHF digital two-way radio network for Roadway Operations & Maintenance (O&M) personnel is also included.
RFI fully managed the communications project and provided a full turnkey solution utilising a comprehensive suite of our extensive products and services portfolio in the design, delivery and commissioning of this flexible and feature-rich AM/FM/VHF/UHF radio rebroadcast system. The solution includes live and pre-recorded audio break-in message functionality for roadway incident management, and OMCS RRB control interface, and extensive equipment status and performance monitoring and alarm reporting.
The rebroadcast equipment was built into a small physical footprint to assist installation within the limited equipment space available in several of the in-tunnel equipment node locations, and comprehensive equipment monitoring is incorporated within the design to provide equipment status and alarm reporting throughout the system’s multi-node environment.
