15-Second Deployment & MIIT Award: Dagong Technology's Tethered UAV Upsets Giants at PT EXPO 2017

Beijing, China — In a stunning upset that reshaped the landscape of global telecommunications, Beijing Dagong Technology Co., Ltd. eclipsed industry giants at the 2017 China International Information Communication Exhibition (PT EXPO CHINA) on September 27. Operating from a modest 20-square-meter booth in the E3 Pavilion, Dagong Technology’s tethered UAV system executed a historic live flight demonstration, securing the prestigious "ICT China 2017 Innovative Application Award" and becoming the world's first tethered drone system officially certified by the Ministry of Industry and Information Technology (MIIT) for network access.

While conglomerates like Huawei and ZTE commanded sprawling exhibits showcasing terrestrial 5G infrastructure, it was Dagong Technology’s "airborne base station" that drew the densest crowds of communication experts. The company's engineering team delivered a textbook demonstration of emergency communication supremacy, anchored by three unprecedented feats: a 15-second rapid deployment to a 100-meter altitude, unshakable stability in simulated Level 8 typhoons (17.2m/s), and an 18-hour continuous full-load flight that shattered industry endurance records.

The spectacle was underpinned by hardcore technological breakthroughs that left global attendees in awe. At the core of the system’s unrivaled performance was Dagong Technology’s proprietary photoelectric composite power supply. Utilizing a staggeringly thin 4.2mm fiber-optic composite cable, the system transmitted 1.5kW of power with a loss rate of less than 3%—drastically outperforming the 8% industry average. Paired with an intelligent wind-resistance system featuring millimeter-wave radar and a three-redundancy flight control system, the drone maintained a camera vibration of less than 0.1° and a positioning accuracy of ±0.5 meters, even in violent gusts.

The live demonstration also showcased the system's modular payload versatility, proving its efficacy across multiple emergency scenarios:

· 4G Base Station: Supported 1,000 concurrent user accesses with a downlink rate of 120Mbps, covering a 2-kilometer radius.

· LiDAR Scanning: Achieved ±5cm 3D modeling accuracy, covering 1 square kilometer per scan.

· Environmental Monitoring: Delivered National Standard Grade A detection precision for PM2.5, temperature, humidity, and gas.

However, it was the system’s proven combat record that solidified its authority. Just one month prior, during the devastating Jiuzhaigou earthquake in August 2017, Dagong Technology’s tethered UAV had restored communication in a miraculous 3 hours, sustaining 72 hours of continuous operation amidst relentless aftershocks and supporting 2,000 concurrent calls. Similarly, during the Hunan anti-flood efforts in July 2017, the system maintained stable signals even 5 meters underwater and transmitted over 12,000 rescue directives.

The fusion of live exhibition brilliance and frontline validation catalyzed a paradigm shift. During the exhibition, Dagong Technology jointly demonstrated a 5G + tethered UAV intelligent inspection with Huawei and China Mobile, validating the feasibility of an "Air-Space-Ground" integrated network. The company also released the Tethered UAV Emergency Communication White Paper, disclosing 72 critical test datasets to propel industry standardization.

The impact was immediate and resounding. The booth welcomed over 30,000 professional visitors, generated 47 strategic partnership intentions, and was voted the number one technology exhibition area in the show's history. Consequently, the system was officially inducted into the National Emergency Communication Reserve System by the Ministry of Emergency Management.

This watershed moment at PT EXPO 2017 was the culmination of a decade of relentless R&D. From conquering electromagnetic compatibility hurdles in 2007 and achieving a 1,000-meter altitude breakthrough in Tibet in 2015, to securing the global first 4G payload MIIT certification in 2017, Dagong Technology has forged an unassailable technological moat. Today, with a complete product matrix covering 50 to 400-meter altitude limits, over 100 cumulative patents, and participation in drafting three national standards, Beijing Dagong Technology has definitively proven that true innovation is born from solving real-world crises—and that a 20-square-meter booth can indeed change the world.
