1.Background Introduction

Emergency communication is a specialized system designed to respond to natural disasters or public emergencies by integrating multi-dimensional communication resources and establishing rapid response mechanisms to ensure rescue command and critical communication. When conventional communication infrastructure is damaged by disasters, the MESH ad-hoc network communication system can overcome reliance on traditional networks, achieving highly reliable communication in complex environments. It provides critical support for rescue operations, personnel dispatch, and resource allocation, becoming a core technological safeguard in emergency management systems.

CroSkylink MESH ad-hoc network emergency communication system, centered on "high reliability, wide coverage, and rapid response," delivers 24/7, all-terrain, and full-service communication guarantees for emergency rescues through technological innovation and scenario-based design. It aids in constructing a smart emergency management system, maximizing the protection of people's lives and property.

2. Application Requirements

Current emergency communication faces three core challenges:

• 1.Insufficient on-site perception: Delayed disaster information acquisition affects decision-making efficiency.
• 2.Cross-department coordination difficulties: Inconsistent communication protocols among multiple rescue forces lead to low collaboration efficiency.
• 3.Urgent need for visual dispatch: Insufficient audio-video transmission capabilities hinder real-time command requirements.

CroSkylink MESH emergency communication system deeply integrates video surveillance, data collection, broadband trunking, and other functions, building an "Edge-Cloud" integrated architecture. It supports real-time multi-source information transmission and intelligent analysis, providing command centers with comprehensive situational awareness and significantly enhancing the precision and timeliness of emergency responses.
