1. Industry Background

In remote areas such as mountains, forests, and tunnels, traditional ground communication networks and public mobile networks often suffer from coverage gaps or infrastructure damage, posing significant challenges for rescue fleets during missions:

• Information Isolation: Communication breakdown between command centers and on-site rescue teams, hindering real-time situational awareness;
• Low Coordination Efficiency: Blocked voice communication and delayed video data transmission between vehicles, impacting unified dispatch and emergency response;
• High Safety Risks: Delays in reporting emergencies, leading to decision-making and response lags.

Wireless ad-hoc network technology, with its flexible deployment, decentralized architecture, and strong anti-interference capabilities, has emerged as a core solution to address these challenges.
