Design and verification of an emergency communication system

In this paper, we designed a two-layer emergency communication network integrating remote backhaul and on-site coverage to address the issues of complex terrain and limited public network coverage, which makes emergency rescue communication unable to be guaranteed. On the one hand, this network can support on-site coverage of mobile nodes to meet the needs of on-site command and scheduling, on the other hand, it supports long-distance backhaul, which can connect the site with the rear. On site testing has shown that the system can meet the joint command needs of multiple departments in emergency situations and achieve the need for command extension to the site.
