The network includes Tetra trunking with full redundancy, as well as “highly customised” train-borne radio, a dispatch and control solution, and flexible frequency planning. It is designed to ensure “smooth communication” between the train driver, stations and the control centre.
Yanto Yulianto, department head of signalling, telecommunication and IT, MRT said: “Without this radio, we would be facing a lack of communication. We would be facing a lot of difficulties. Another reason for selecting Hytera was because [of the need for] interoperability.”
The MRT Line 1 – phase 1 – is just under 16 kilometres long and connects Lebak Bulus and Bundaran HI, both above and below ground. It is estimated that the line will serve 212,000 passengers per day.
