The Public Transport Authority of Western Australia have selected Nokia to modernise rail communications in Perth with private wireless and IP/MPLS technologies. The Public Transport Authority of Western Australia (PTA) have selected to design, build, and maintain a next generation railway communications system over the next decade in Perth. METRONET infrastructure and public transport programme is the long-term blueprint for Perth’s future. As a critical element of the METRONET program and as part of the agreement, more than 160 LTE/4.9G radio sites will be built to modernise the railway communication system that includes additional METRONET track and tunnels with a total of 250km of railway. The solution will be based on Nokia private 4.9G/LTE mission-critical IP/MPLS, Data Center Fabric and microwave backhaul solutions, to support a Communications Based Train Control (CBTC) High-Capacity Signalling system for greater accuracy and efficiency compared to traditional signalling systems.
