The most important factor in the remote control environment of the unmanned system is the reliability of wireless communication. As a method for improving the reliability and performance of communication, there is a system improvement method such as using an advanced antenna and a repeater, and a method using an algorithm such as automatic traffic control. In this paper, system design and control algorithms are proposed by adding redundancy concepts to these methods. The reliability and performance of the proposed system which has the redundant structure providing seamless video are compared with those of the existing system.
