Problems solved by technology
In the railway communication system, wireless train dispatching communication is a very important way of traffic command communication. It is an important means to ensure traffic communication between dispatchers, station attendants, locomotive drivers, and train commanders. Therefore, the reliability and reliability of communication must be guaranteed. However, in mountainous areas with complex terrains and places where the electric wave transmission of tunnel lights is difficult, communication cannot be carried out due to too much attenuation of signal field strength, which brings great inconvenience to railway communication
