Huawei, in partnership with China Railway Signal & Communication (CRSC) and China Telecom the built dedicated telecom railway network for the Jakarta–Bandung high-speed railway known as the Whoosh. This network facilitates real-time communications, control, and dispatching of the trains, providing reliable and robust technical support for intelligent, safe, and efficient train operations.
The Whoosh is equipped with the Chinese Train Control System Level 3 (CTCS-3), which was independently developed in China. Due to the high speed at which the trains travel and their short departure intervals, a stable and reliable dedicated communications network that provides high security, large bandwidth, and simple O&M is crucial for the train control system. This guarantees that the trains run safely, smoothly, and efficiently.
“The Whoosh’s train-to-ground wireless network adopts Huawei’s mature solution and employs interleaving in networking for seamless coverage. By achieving up to 99.99% availability, the network ensures the stable transmission of train control signals and the intelligent orchestration and scheduling of train numbers and function numbers,” Lai Chaosen, the Vice President of Huawei Indonesia, said.
The data network uses Huawei’s next-generation data communications equipment, which guarantees 100% secure networks through native hard pipes. Every link is protected by redundancy, and redundancy switchover can be completed within just 35 milliseconds.
The transmission network uses Huawei’s Hybrid MSTP equipment, which provides the large bandwidth and high stability required by over 20 high-speed train systems, such as scheduling and command, disaster prevention, video surveillance, passenger ticketing, and power telecontrol systems. The network is also capable of addressing the growth and evolution requirements of future railway services.
Jakarta–Bandung high-speed railway spans 142.3 km between the capital city and the popular tourist destination of Bandung in Indonesia, allowing trains to operate at a maximum speed of 350 km/h. The Whoosh is also the first project that applies China’s high-speed railway system, including all elements of the industry value chain, outside China.
