High accuracy measurement of radio wave propagation characteristics in space
In the method for measuring/simulating the radio wave propagation characteristics in the space, the simulation is carried out by reflecting the interference to the measurement value derived from the cable caused by the wired connection between the measurement equipment, the specification of the radio communication adopted when the measurement equipment is connected wirelessly, the effect of the shape of the space and the existence of the obstacle in the space, but there was a problem in the accuracy of the simulation result. In the radio wave measurement technology introduced this time, the above-mentioned problem was solved by carrying out the radio wave measurement using the radio communication between the measurement equipment (base station and mobile terminal). In this technology, the time, frequency and phase are synchronized with each other between the base station and the mobile terminal, and the propagation characteristics of the radio wave which carries out radio communication between the mobile terminal and the base station moving in the measurement object space are continuously measured in time series in association with each position information of the mobile terminal. Currently, some principle verification has been carried out on the radio wave measurement result/visualization in the case of propagation failure, etc.

Company information
The revenue generated from technology transfer is reinvested as new research funding for universities and researchers, and is utilized to create further research outcomes. To ensure the smooth operation of this cycle, known as the "Intellectual Creation Cycle," we will vigorously promote technology transfer. The types of seeds we handle include patents, know-how, databases, and programs. We have established a collaborative framework by signing basic technology transfer agreements with the following universities (as of June 1, 2025): Tohoku University, Hirosaki University, Iwate University, Akita University, Fukushima University, Yamagata University, Tohoku Gakuin University, Iwate Medical University, Fukushima Medical University, Aizu University, Miyagi University, Hokkaido University, Muroran Institute of Technology, and Showa Medical University.
