The Cyber-Physical System (CPS) project
Internet of Things, commonly known as IoT, has been sweeping around the world as the newest "wave" of innovation trend.
The Internet of Things (IoT) describes the network of physical objects—“things”—that are embedded with sensors, software, and other technologies for the purpose of connecting and exchanging data with other devices and systems over the internet.
Over the past few years, IoT has become one of the most important technologies of the 21st century. Now that we can connect everyday objects—kitchen appliances, cars, thermostats, baby monitors—to the internet via embedded devices, seamless communication is possible between people, processes, and things.
By means of low-cost computing, the cloud, big data, analytics, and mobile technologies, physical things can share and collect data with minimal human intervention. In this hyperconnected world, digital systems can record, monitor, and adjust each interaction between connected things. The physical world meets the digital world—and they cooperate.

Japan also recognizes the importance of pursuing cyber physical system (CPS), a new concept targeting new value through information linkage between the physical world and cyberspace (JEITA ).
Overall, CPS refers to the world where big data from a vast array of sensors in the physical space are processed using computing tools (such as emulator and AI) in the cyber space in order to generate solutions back to the physical space.
JEITA (Japan Electronics and Information Technology Industries Association) envisioned IT and electronics industry to serve as a platform which partners with car electronics, healthcare, energy, social infrastructure and other future growth areas to resolve the social problems facing Japan and create new business
To promote the development of CPS/IoT, JEITA established the CPS Task Force in July 2015 whose main jobs are to work with "government agencies, universities, and relevant organizations and associations in and beyond Japan to create the innovative products and services needed to underpin a CPS/IoT-driven society and resolve the various problems confronting society today."

The Wireless Emulator project
Project overview
A fundamental part of any Cyber-Physical Systems is the communication between components. Since everything is going wireless recently, the Wireless Communication aspect of CPS is highly focused. Therefore, an "emulator" that can emulate the wireless communication in the physical space into the cyber space is highly needed.
As a result, the Japanese Ministry of Internal Affairs and Communications, proposed the "Wireless Emulator" project, which aims for the realization of high-precision radio wave emulator in cyberspace.
MIC (the ministry) is implementing the project on the realization of high-precision radio wave emulator in cyberspace to develop large-scale wireless emulator that emulates various radio wave utilization systems with high precision in cyberspace.
In this project, a radio wave emulator will be developed, which can emulate various radio wave systems with high precision in cyberspace in real time. The purpose of the project is to provide a testbed that will enable various operators involved in radio wave systems to design, evaluate, and verify infrastructure, systems, platforms, applications, and services.

My contribution
In our lab in Tokyo Tech, we are working on the emulation of the real world into the cyber space. Specifically, for my part, I am developing methods to utilize stochastic wireless channel models, combining with data assimilation and interpolation, in order to compute the channel respond at locations where measurement data are absent. However, due to the nature of being an on-going project, the details of my research are intentionally left out of this online article.
