The development of magnetic levitation trains in China has enabled them to improve their ability to reach speeds of up to 1,000 km/h. They were designed to operate within near-vacuum tubes, and could exceed the speeds of commercial aircraft.
The Chinese magnetic levitation train
The idea of travelling at over 1,000 km/h seems like an incredible achievement, but the real challenge is to maintain stable communication between passengers and telecommunications base stations. When speeds are close to the speed of sound, electromagnetic signals are severely affected by frequency changes due to the displacement of the mobile receiver and the main data station.
A research team led by Professor Song Tiecheng from the National Key Laboratory of Mobile Communications at Southeast University is leading the research that suggests parallel wire placement on the inner walls of the vacuum tube, which would allow for a stable and continuous connection. In addition, by using advanced coding techniques and adjusting key signal parameters, disturbances caused by frequency changes can be minimized.
The application of this technology, similar to the ” Hyperloop ” concept proposed by Elon Musk, is being developed on a large scale in China, the only country currently moving forward with the implementation of magnetic levitation trains inside vacuum tubes. If all goes according to plan, these high-speed train lines are expected to improve the way we travel over long distances.
Backed by technological research and collaborations with the China Aerospace Science and Industry Corporation , this project promises to be a revolution in both the fields of transportation and telecommunications.
