Application of Wireless Communication Technology in Tunnel Communication

Tunnel wireless communication refers to the erection of invisible bridges in the winding underground corridor, allowing the radio waves of information to shuttle between the thick rock walls. Nowadays, with the rapid development of transportation, more and more subways, railways and highway tunnels have been built, but there are still some problems in communication in the tunnel that have not been solved. For this reason, many companies and research teams around the world are trying to apply communication technology on the ground to tunnel communication. At present, some of these ideas and attempts have developed into adoptable and mature technologies. So, tunnel wireless communication is not only a demonstration of technology, but also a guardian of safety and efficiency. This paper mainly uses literature analysis to study the basic principles of communication technology and its application in follow-up communication. This article finds that the communication technology currently applied in tunnel communication is Multiple-Input Multiple-Output (MIMO) technology, General Packet Radio Service (GPRS) technology, Synchronous Digital Hierarchy (SDH) technology, collaborative relay technology, Zig Bee technology and WiMAX technology.
