Far EasTone Telecommunication launches' High Speed Rail 2.0 'communication quality upgrade plan

        To enhance the experience of public transportation services, Taiwan High Speed Rail signed a memorandum of cooperation with three major telecommunications operators on March 25th for the "High Speed Rail 2.0" communication quality upgrade plan. In the future, Taiwan High Speed Rail will provide the site and electricity, and telecommunications operators will invest in its construction. It is expected that by the end of 2026, the communication quality of the underground section and some tunnel sections from Nangang to Banqiao can be significantly improved, and the entire line will be completed by the end of 2027.

                At present, 369 sets of "basic frequency repeaters" have been installed along the high-speed rail line for more than 10 years. Taiwan's high-speed rail and three major telecommunications companies plan to fully replace them with new "fiber radio frequency amplifiers" (RRH), with an estimated number of over 2200 to overcome the signal discontinuity and bandwidth bottleneck of trains traveling at high speeds. In February 2026, technical trials began at key base stations such as the Nangang Banqiao underground tunnel and the continuous tunnel group along the line, to confirm that the signal can be significantly improved when the high-speed rail is in tunnels and underground sections. Subsequently, it will be expanded to open sections such as Yunjianan to improve the 4G/5G mobile communication quality of the entire line. In addition, to ensure the safety of high-speed rail operations, this upgrade plan can only be carried out during the night time period of about 4 hours after the train ends, and it is estimated that more than tens of thousands of people will be mobilized, making the project extremely challenging.

        The Taiwan high-speed railway is an important transportation hub for people traveling north and south, with a total length of 350 kilometers and passing through 52 tunnels/underground sections. The total length is 68 kilometers, accounting for about 19%. Although communication has been improved, the enclosed environment inside the tunnels has always been a communication bottleneck. Far EasTone Telecommunication Chee Ching President expressed his pleasure in assisting in upgrading the quality of train communication. Through advanced mobile communication architecture and new generation 5G devices, critical infrastructure and overall network resilience can be strengthened, allowing users to feel a smooth connection without distance when taking high-speed trains, whether using mobile calls, browsing the web, or watching videos, and enjoy a stable and high-quality mobile communication experience.
