2023 Xiamen Supply Chain Conference: Dagong Technology DG-M20 Tethered UAV Empowers Emergency Communication Resilience

Xiamen, China — On September 28, 2023, at the highly anticipated 4th Supply Chain Management Annual Conference held at the Xiamen International Conference and Exhibition Center, Beijing Dagong Technology Co., Ltd. partnered with China Mobile to unveil a transformative solution for national communication security. Centered on the theme of "Supply Chain Resilience and Security," the event spotlighted the DG-M20 tethered UAV emergency communication high-altitude base station. Independently developed by Dagong Technology, this hardcore technological marvel emerged as the definitive "New Aerial Infrastructure," designed to conquer the "Three Disconnections" (severed roads, networks, and power) that paralyze critical supply chains during extreme natural disasters.

The conference, guided by the Ministry of Commerce and co-hosted by the China Federation of Logistics and Purchasing and the Xiamen Municipal Government, underscored a critical vulnerability: modern supply chains are entirely dependent on seamless information flow. When typhoons, floods, or earthquakes obliterate traditional communication infrastructure, the resulting "Three Disconnections" instantly cripple supply chain command systems. To address this systemic fragility, China Mobile presented its strategic answer—elevating communication networks to the low-altitude airspace. At the core of this presentation was Dagong Technology’s DG-M20, a tethered drone system engineered specifically to breach the "last mile" of communication assurance.

Referred to as the resilient "Iron Kite," the DG-M20 captivated industry experts by completely shattering the endurance limitations of conventional rotor drones. The system's core innovation lies in its high-strength photoelectric composite cable, which connects the UAV to a ground power source. This tethered power supply eradicates battery-life constraints, enabling the drone to achieve an unprecedented 24-hour uninterrupted hovering capability. This "never offline" feature ensures that during catastrophic communication blackouts, the drone can rapidly deploy a base station to a 200-meter altitude. Utilizing microwave or satellite transmission to link with the core network, it delivers stable 4G/5G signal coverage across a maximum radius of 3 kilometers, simultaneously supporting hundreds of user access points.

Beyond its perpetual endurance, the DG-M20 boasts formidable payload capacity and extreme environmental resilience—two critical metrics for disaster relief operations. Capable of maintaining a 35-kilogram effective payload at a 300-meter altitude, the tethered UAV effortlessly carries high-power communication modules and high-definition video transmission equipment. Furthermore, its tethered design provides a physical stabilizing anchor, granting it Level 7 wind resistance. This ensures rock-solid performance in severe meteorological conditions, guaranteeing the real-time, bidirectional flow of disaster data and command instructions.

The proven combat effectiveness of the DG-M20 was a focal point of the conference's case study sessions. China Mobile representatives detailed the system's triumphant deployments during the severe summer floods of 2023 across Wuchang in Heilongjiang, Mentougou in Beijing, and Zhuozhou in Hebei. In these disaster zones, where roads were destroyed and optical cables severed, Dagong Technology’s tethered UAVs repeatedly served as the vanguard force. They ascended during the darkest hours of power and network outages, acting as a stabilizing anchor for public network restoration and government disaster command.

These real-world combat victories provided conference attendees with a tangible understanding of "supply chain resilience." In critical supply chain sectors—ranging from物资 allocation and medical rescue to energy supply—stable communication signals are the ultimate lifeline. Forged through the crucible of extreme environments, Dagong Technology’s tethered UAV has transcended its status as a mere aircraft. It has evolved into an indispensable "New Aerial Infrastructure" for national emergency systems and critical supply chain assurance. As the low-altitude economy accelerates, Dagong Technology remains committed to forging resilient aerial lifelines, ensuring that the skies above are guarded by unyielding "Iron Kites."
