Urban disaster emergency rescue often takes place in complex scenarios including high-rise buildings, underground spaces, large-scale complexes and urban tunnels, where building structures cause severe signal occlusion and poor communication penetration. In the event of major disasters such as earthquakes, floods and mudslides, traditional public and private network infrastructures are easily damaged and paralyzed, resulting in the failure of conventional wired and wireless communications. Large-scale signal blind zones and communication outages on site seriously hinder the progress of rescue operations.

Traditional communication solutions cannot meet the practical needs of complex disaster scenarios, featuring incomplete signal coverage, inaccurate positioning and unstable audio and video transmission. They fail to effectively manage internal rescue personnel and support precise rescue operations. In addition, it is difficult to quickly build independent communication links at disaster sites, leading to poor information interaction, delayed data backhaul and low collaborative efficiency between the site and the rear command center, which greatly restricts emergency response and disposal capabilities. Therefore, urban emergency rescue urgently requires a self-organizing network communication solution that is independent, rapidly deployable, full-coverage and self-healing to solve communication disconnection problems in extreme scenarios.

Targeting communication challenges in complex urban buildings and major disasters, this solution adopts mature wireless ad hoc network technology, which is compatible with existing emergency communication equipment and integrates public network, private network, wired and wireless communication resources. It builds a comprehensive urban disaster emergency communication guarantee system with rapid deployment, wide coverage, high reliability and full interoperability, solving extreme communication paralysis and improving on-site rescue, personnel management and collaborative command capabilities.
