Defying Level 8 Winds: Dagong Technology's Tethered UAV Wins Gold at London Tech Expo
London, UK — In a defining moment for global通信technology, Beijing Dagong Technology Co., Ltd. silenced skeptics and rivaled industry titans at the 2017 Global Communications Technology Expo. On September 30, within the bustling "Future Communication" zone of the E3 Pavilion, Dagong Technology’s tethered UAV system executed a flawless flight demonstration under simulated Level 8 gusts (17.2m/s), earning the prestigious "Annual Innovation Communication Technology Gold Award" and securing strategic partnerships with European giants Vodafone and Deutsche Telekom.
While Huawei and ZTE showcased terrestrial 5G infrastructure nearby, Dagong Technology’s modest 20-square-meter booth became the epicenter of "Air-Space Integration" innovation. The engineering team achieved a remarkable "15-minute rapid deployment," lifting a 4G base station into a stable hover. The system demonstrated an unprecedented triple breakthrough: maintaining camera vibration below 0.1° via a three-axis gimbal, switching to "Hurricane Mode" for ±0.5m positioning accuracy in turbulent wind fields scanned by millimeter-wave radar, and transmitting a flawless livestream of the Thames River inspection.
The technological prowess on display was underpinned by proprietary innovations that solved critical industry pain points. At the heart of the system was a globally pioneering "photoelectric composite power supply" technology. Utilizing a mere 4.2mm diameter fiber-optic composite cable—slimmer and lighter than industry standards—the system achieved a transmission power of 1.5kW with a loss rate of less than 2.8%, a stark improvement over the industry average of 8%. This allowed for synchronized ground power from photovoltaic panels and diesel generators, ensuring sustained operation.
The performance in London was not merely a trade show spectacle, but a validation of combat-proven reliability. Just weeks prior, during the devastating Jiuzhaigou earthquake in August 2017, Dagong Technology’s tethered UAV had restored emergency communication in a miraculous 15 minutes. Operating amidst relentless aftershocks, the system provided 72 hours of continuous coverage, supporting 1,000 concurrent users with a downlink rate of 120Mbps. This "Golden 1 Hour" emergency response mechanism—capable of reaching disaster sites 80% faster than traditional methods—solidified the system's reputation as the global benchmark for reliability.
The precision engineering extended to its modular payload design, capable of integrating 4G base stations, environmental monitors (National Standard Grade A accuracy), and LiDAR for ±5cm 3D modeling. Post-exhibition validation was swift: a German engineer’s rigorous 72-hour stress test concluded with a handshake, declaring, "This is a true industrial-grade product." Consequently, Dagong Technology’s system was officially inducted into the EU Emergency Communication Reserve System.
This milestone marks the culmination of a decade of R&D. From conquering electromagnetic compatibility challenges in tethered cables in 2007 to breaking the 1,000-meter altitude limit in Tibet, Dagong Technology has built a comprehensive product matrix covering 50-600m altitude limits. Holding over 100 patents and participating in the formulation of 3 national standards, the company has proven that true innovation—embodied by the "Chinese Starlink" rising over the Thames—is about solving real-world challenges with absolute technical authority.
