A key challenge for developing networked Cyber-Physical System is how to integrate and process the virtual and real-world information from locally or remotely connected humans/robotics with a tolerable application latency. In this paper, we investigate the improvement of application latency by introducing edge computing environments and the resulting service quality through some experiments. A network-oriented mixed-reality (MR) application that operates a remote robot through users' gestures and displays location-aware information through edge server is implemented as a simplified implementation of cyber-physical networking applications. The results of our experiments reveal that service quality suddenly gets worse when application latency becomes around 1 [sec]. In other words, the service quality of the network-oriented MR application is expected to be improved by introducing edge computing when latency of application running on cloud computing environments is about 1 [sec].
