Based on the analysis of the broad band wireless communication, we design a wireless terrain network with some different subnet of satellite, microwave, LTE, and so on. OPNET provides a virtual network environment, through the modeling of the network. We give the simulation flow of the wireless communication. It designs the station node and satellite node, and builds a simulation system for the broad band wireless communication by OPNET. According the wireless communication topology, it realizes the network simulation system with six zone subnets which contain six single users and two communication vehicles. It contains the communication satellites which use the transparent transponders. The simulation system can display the dynamic route by the simulation system. It also can analyze the performance and efficiency of the wireless system with the parameters, such as: throughput, delay, processing delay, Packet Loss Ratio. It can use “Failure Recovery” module in the simulation system and set the parameters and analyze the communication system influence.
