Design of an Interface Device Combining Mobile Communication and Fixed Communication

摘要

Aiming at the problem that interface A of the locomotive spread spectrum relay equipment or interface A of vehicle controlled communication equipment group cannot realize 2Mbps link interconnection with optical fiber equipment of fixed communication station, an interface equipment based on the combination of mobile communication and fixed communication is proposed. For the overall design, modular structure, large-scale integrated circuit and single-chip processing technology are adopted to realize the seamless connection between fiber optical transmission equipment and a spread spectrum relay equipment and complete the voice, data, image and video multi-service transmission function integrating fiber optical transmission network, mobile communication network and computer network. It is tried in the plateau environment and the communication distance can reach 100km while the network operation is normal and stable.
