For the underground special environment, in the subway station, through the network topology of chain relay and network, the wireless multi-hop network is rapidly deployed and constructed, relay transmission is relayed, which effectively solves the problem of wireless signal occlusion and realizes the wireless communication between ground and underground.
In the subway application scenario, the traditional network laying maintenance cost is high, and the mobile scalability is poor. The wireless MESH network is easy to deploy, flexible to use, and simple to operate. It can effectively reduce network construction and operation and maintenance costs, and can meet the needs of staff to move freely with tasks. It can also flexibly adjust the deployment of video surveillance nodes to avoid monitoring blind spots.
Centerless, all-IP MESH broadband system self-healing self-connection, network robustness and resistance to destruction, lack of any node, still work properly, It can be used as a coverage extension of the existing wireless communication private network in the subway to realize converged communication, and can also be used as an emergency backup transmission guarantee for the local failure of the operator's public network in the subway.
