Shanghai Telecom has officially launched the Hangzhou Bay area's first 5G-A low-altitude communication network in Shanghai's Fengxian District this week, marking a significant milestone in low-altitude network development.
According to Shanghai Telecom representatives, after half year of testing and optimization, the company has built the first 5G-A low-altitude network covering the entire Fengxian area, ensuring safety, reliability, and high-efficiency coordination. Leveraging 5G-A's ultra-reliability, ultra-low latency, and air-space-ground integration capabilities, the network effectively meets the operational demands of low-altitude aircraft, supporting high-density operations, high-frequency communications, comprehensive coverage, massive device connectivity, real-time responsiveness, and enhanced security standards.
As a pioneering infrastructure in Hangzhou Bay, this 5G-A low-altitude network features an innovative "single-network dual-carrier" architecture, with the 3.4-3.5GHz primary carrier dedicated to ground communications while the 3.5-3.6GHz secondary carrier simultaneously serves both low-altitude and terrestrial users. Through sophisticated beamforming adjustments and parameter optimization, the network achieves secure and stable coverage extending up to 120 meters in altitude.
Post-deployment results show a qualitative leap in low-altitude application performance. The network has achieved significantly expanded coverage range and markedly enhanced control responsiveness. With network excellence rates consistently exceeding 95% and uplink speed performance improving by over 30%, the system has demonstrated remarkable reliability by maintaining zero connection drops throughout 150-kilometer flight tests.
