Based on the concept of railway private network, the low-altitude intelligent network with endogenous security of Pre6G is constructed, and products such as lightweight core network, dedicated base station and airborne terminal are provided. The low-altitude network adopts the heterogeneous fusion architecture of airspace private network and ground hotspot coverage to meet the communication, navigation and monitoring requirements of aircraft in low-altitude flight and ground take-off and landing phases.

1. low-altitude airspace private network

Pre6G cellular-free large-scale MIMO technology is adopted, and the multi-RRU data deployed in the high tower are aggregated to the base station BBU/CU+DU for joint processing, and the coverage radius of a single tower and a single cell exceeds 30km, thus eliminating mutual interference and frequent handover between traditional cells; The edge communication rate of single terminal reaches 5Mbps, which meets the demand of real-time backhaul of high-definition video.

2. Ground hot spots

Covering the landing field and landing point of UAV, the micro-power base station is used to supplement the hotspots, and the core network is shared with the low-altitude airspace private network to form a converged network to realize the precise landing of UAV.

3. Airborne terminal

It integrates low-power communication, high-precision positioning and safety management and control functions, and a single device integrates the functional requirements of low-altitude communication, guidance and monitoring.
