Wireless-link-quality Prediction and Device-position Estimation Based on Relationship between Wireless-communication-link and Physical-space Information

Abstract

Various wireless terminals are being connected to a network via wireless communication accesses, and the number of wireless terminals and their traffic are steadily increasing. The information from a huge number of connected devices is expected to be a foundation of new services. The Cabinet Office of Japan proposed Society 5.0, where people, things, and systems are all connected in cyberspace. The optimal results obtained through artificial intelligence will bring new value to industry and society. Society 5.0 is achieved by the convergence between cyberspace and physical space. Innovative Optical and Wireless Network (IOWN) will accelerate the obtaining of physical-space information from a number of various sensors. This article introduces two technologies that use the relationship between physical-space information and wireless-communication-link information for new services in Society 5.0; 1) wireless-link-quality prediction using camera images and 2) device-position estimation using Wi-Fi feedback signals.
