About

Keishi Yamaguchi is a researcher specializing in industrial wireless communications, with a particular focus on applying Wireless Local Area Network (WLAN) technologies to factory automation environments. His work centers on a critical challenge in modern manufacturing: enabling reliable, fast, and deterministic wireless control of industrial robots (iRBs) in demanding factory settings where communication delays can have serious operational consequences. Yamaguchi's most significant contribution is the development of a synchronous multi-user round-robin transmission protocol for industrial WLAN (iWLAN) systems, designed to minimize overhead while ensuring both speed and safety in machine-to-machine communications. Building on this foundation, he extended his research to address large-scale factory deployments, proposing innovative zero-delay roaming solutions that allow seamless handoffs between multiple access points — a crucial capability for robots operating across expansive factory floors. His body of work, accumulating approximately 27 citations across four closely related publications, reflects a methodical, iterative approach to solving real-world industrial networking problems. By progressively refining protocols for safety, security, and scalability, Yamaguchi has made meaningful contributions to the emerging field of Industrial Internet of Things (IIoT) and smart manufacturing communications infrastructure.
