In recent years, wireless networks and applications have achieved marvelous successes in government, enterprise, home or even person- al communication systems. The desired features of wireless communications draw lots of atten- tion to the industrial communication and ex- pected to bring benefits such as reduce deploy- ment and maintenance after employed. However, the industrial communication system required “real-time” communication which means the control systems in the factory are required accu- rate control and rapid communication, such as the industrial motion control system. In this type of application, the communication system’s per- formance and efficiency will be evaluated to ensure its applicable to the industrial network. However, there are a few original issues in the wireless communication, such as fading, multi- path propagation and interference problems which will affect the reliability and performance of industrial communication system operation. Therefore, we proposed a network connection protection mechanism that cooperate wireless network and visible light communication to achieve reliability and performance in industrial communication network, we will consider to implement this mechanism by using industrial wireless ethernet in the near future.
