Project Overview Trantek MST was tasked with the design and installation of an upgrade to the Sydney Harbour Tunnel intelligent transport system in NSW, Australia. The Sydney Harbour Tunnel is one of Sydney’s primary transport routes, with busy vehicular traffic using the tunnel 24 hours a day, 7 days a week.  The AM/FM radio rebroadcast system is a relatively minor, but vital, component of the overall total intelligent transport system not only to maintain the rebroadcast of AM and FM radio stations within the Tunnel, but also to ensure that vital incident management capabilities can be maintained In the event off a sub-system failure. An audio break-in capability allows pre-recorded or live audio announcements to be inserted into the AM and FM rebroadcasts to notify drivers of incident information via their car radios. Trantek MST sought a partner who could design, install and commission the rebroadcast system upgrade as a turnkey sub-contractor. As well as meeting the stringent operational requirements, Trantek MST needed a partner with the experience to handle the challenges of working on one of Sydney’s busiest roadways. Trantek MST selected RFI to provide the rebroadcast system, based on RFI’s experience and expertise with this technology. RFI delivered a flexible and feature-rich rebroadcast system, utilising a comprehensive suite of their products and services, including: - RF surveys - System design - Equipment manufacture - Integration - Factory acceptance testing (FAT) - Installation - Commissioning - Site acceptance testing (SAT) - Coverage testing *“We chose RFI because of their proven technical, manufacturing, installation and integration capabilities. RFI has proven extremely easy to work with, quickly understanding the technical requirements of Trantek MST’s fault resilient architecture and integrating and where necessary manufacturing custom components to achieve a truly satisfying solution”* said Trantek MST Managing Director, Mr Lionel Ascone.
