On November 11, Guangdong Province released the "General Technical Requirements for Low-Altitude Intelligent Internet Digital Infrastructure" for public comment. For the first time at the provincial level, this standard systematically defines the technical boundaries and architectural blueprint for digital infrastructure in low-altitude airspace, filling a standard gap in the integrated coordination of communication, navigation, surveillance, and meteorology. Targeting the operational characteristics of complex airspace from 0 to 600 meters, the standard proposes an overall architecture of "four networks and one center," deeply integrating cloud-edge-device collaboration and multi-source data fusion technologies. The standard aligns with Guangdong Province's strategic deployment as a "Low-Altitude Economy Pioneer Demonstration Zone" and, leveraging the Greater Bay Area's high-penetration 5G/5G-A network foundation, complete intelligent hardware industry chain, and high-frequency, diverse urban low-altitude scenarios, establishes infrastructure specifications suitable for high-density, highly dynamic flight operations.
