| Summary: | Satellite communication and terrestrial mobile communication have strong complemented co-benefits.Satellite Internet is the hot spot supporting current industrial development and an important part of the future 6G network.Global coverage requires interstellar networking, but inter-satellite communication bandwidth requirements and the instability brought by the free space channel pose new challenges to the space bearer network.Inter-satellite communication technologies and link interface technologies were compared and analyzed.An optical transport network (OTN) carrier network solution based on inter-satellite laser was proposed, which could fully leverage the advantages of the maturities and the economies of the scaled ground optical communication.It constructs a satellite-terrestrial integrated network with strong cost-efectivity, compatibility, and scalability.Finally, the technological directions and evolutions of the inter-satellite laser communication were discussed, and suggestions for industrial development in China were proposed. |
