Abstract: The external interactive satellite communication system is a competitive solution for remote education in China. Based on the analysis of the external interactive communication, a new scheme of external interactive satellite communication systems in the network layer is proposed. Details of the system architecture, data processing procedure and key units are also included. Field experiments show that such a system can support both broadcasting and interactive services, which makes it highly flexible and prospective in the applications of distance learning and broadband access network in remote areas.
