As an important infrastructure for national informatization, the integrated network of air, space, and earth has strategic significance far beyond the scope of ordinary communication technology. It is not only a necessary path for China to achieve global information coverage and independent innovation, but also a key layout for grasping the initiative of development in the digital age. From a technical perspective, the innovative integration of the air space integrated network is remarkable. It is not a simple superposition of a single technology, but an organic integration of advanced technologies such as the ground network that evolves from 5G-A to 6G, the low altitude network that promotes low altitude economy, and the low orbit satellite Internet that accelerates large-scale networking, forming a multi-level communication system of "ground support, air blinding, and space coverage". This integration not only achieves a leap in broadband transmission capability, but also endows communication networks with strong risk resistance. In extreme disaster environments such as earthquakes and floods, when ground base stations are damaged, drone relays and satellite networks can quickly replenish their positions, ensuring uninterrupted emergency communication links and providing key support for disaster relief and safeguarding people's livelihoods. This is an advantage that traditional communication networks cannot compare with. At present, the process of integrated communication between air, space, and earth in China has pressed the "acceleration button", and a series of positive changes have demonstrated strong development momentum: the ground network continues to evolve towards 6G, providing technical reserves for future communication with higher speed and lower latency; The development of low altitude networks has given rise to new business models such as drone logistics and low altitude tourism, injecting new vitality into the low altitude economy; The intensive launch of low earth orbit satellites has accelerated the large-scale networking process of satellite Internet, and promoted China to take the lead in the field of space communications. With the continuous improvement of China's technological strength, the integrated network of air, space, and earth will become an important pillar of China's information construction, providing strong guarantees for achieving high-level technological self-reliance and building a strong cyber nation.
