Application
For the special underground environment in the subway, through a combination of chain relay and mesh network topology in the subway station, the rapid deployment of wireless multi-hop network, relay relay transmission, effective solution to wireless signal masking, to achieve penetrating wireless communication between the ground and underground, to provide reliable, stable, high-speed communication security for the station staff. It can also meet the need for staff to move freely with their work tasks, and can also serve as an emergency backup transmission guarantee in case of local failure of the operator's public network in the subway.
