构建“空天地一体化”保障网络 2025年度最大规模应急通信演练举行

Core Viewpoint - The "Communication Mission-2025" emergency communication drill held in Wuhan, China, simulated extreme conditions caused by low-temperature rain, snow, and ice, focusing on enhancing emergency communication capabilities and infrastructure [1]. Group 1: Emergency Communication Drill - The drill involved over 400 participants and utilized 23 emergency communication drones along with more than 300 sets of various emergency communication equipment [1]. - Five practical scenarios were set up, including disaster warning prevention, emergency communication command system construction, and communication support for the "three disconnections" (disruption of roads, power, and networks) [1]. - The Ministry of Industry and Information Technology emphasized the need to reduce reliance on traditional ground communication networks and explore new technologies for an integrated "space-ground-air" communication network [1]. Group 2: Technological Innovations - The drill showcased advanced technologies such as the Tian Tong smart emergency communication helmet, which supports communication via 4G/5G networks, Beidou system, and Tian Tong satellites, along with real-time video transmission capabilities [2]. - A drone equipped with laser communication technology was demonstrated, capable of establishing aerial networks to ensure long-distance and high-bandwidth communication when ground communication is disrupted [3]. - An unmanned airship was also deployed, capable of operating at altitudes of 500 to 1000 meters for over 15 days, providing emergency communication and 24-hour scanning of disaster areas [2].
