[Guangdong plans to issue the "Technical Requirements for Low-altitude Intelligent Internet Digital Infrastructure" and formulate a technical framework at the provincial level for the first time] On November 11, Guangdong Province's "General Technical Requirements for Low-altitude Intelligent Internet Digital Infrastructure" publicly solicited opinions. For the first time at the provincial level, this standard systematically defines the technical boundaries and architectural blueprint of low-altitude airspace digital infrastructure, filling the gap in standards in the field of integrated coordination of communication, guidance, surveillance and gas. Facing the operational characteristics of complex airspace between 0 and 600 meters, an overall architecture of "four networks and one center" is proposed, which deeply integrates cloud-edge-device collaboration and multi-source data fusion technology. This standard is in line with the strategic deployment of Guangdong Province’s “Low-altitude Economic Pilot Demonstration Zone” and relies on the Greater Bay Area’s high-penetration 5G/5G-A network base, complete intelligent hardware industry chain, and high-frequency and diverse urban low-altitude scenarios to create tailor-made infrastructure specifications suitable for high-density and high-dynamic flight.
