11. Concluding Remarks
The 9th scientific workshop aimed for the lecture to introduce Hokuriku's state-ofthe-art technology for holding in the Hokuriku region. As a result, three lecturers wereinvited to the workshop. Dr. Shimada of the National Institute of Information andCommunications Technology introduced the activities of collaboration in the Hokuriku
region. In particular, he introduced that they were collaborating with some institutes
and companies in Hokuriku using NICT Hokuriku StarBED Technology toward
development of products and services relating IoT. The lecture was very interesting.
Professor Fujimoto of Fukui University gave an introduction to accurately estimate
the position of indoor radio stations using antennas and signal processing technology.
In recent years, position information of wireless terminals is important while IoT in thefactory is progressing. Future use is expected. Finally, Professor Noguchi of Kanazawa
Institute of Technology gave a lecture on energy harvesting by terrestrial digital
broadcasting. In this research, the key technology is how to develop highly efficientantennas. By using this technology, it becomes possible to supply power in a wide areaby using radio waves of terrestrial digital broadcasting. In addition, since thistechnology is an important technology for wireless power transmission, therefore thetechnology is a hot topic in the wireless power transmission technology.
It was a meaningful workshop including the facility tour for thinking about how toproceed research and development in the future for researchers and engineers of radioscience, and it was a good opportunity to understand the outline of Hokuriku's state-ofthe-art technology.

10. The steering committee meeting took place from 13:20 to 14:00 on August 4th,2017 at Okayama University.
11. Concluding Remarks
The 10th scientific workshop was held to study standardization movement of radio
access technologies for IoT in which three lecturers were invited. In the firstpresentation, Dr. Yamamoto explained Narrow Band - IoT which was standardized formobile communication specifications by the 3rd Generation Partnership Project(3GPP). Next, Dr. Takeda explained non-orthogonal multiple access and grant-freeaccess technologies which is being discussed for 5G mobile communication systems.
Finally, Associate Prof. Okamoto introduced 'Low-density signature' and 'Sparse code
multiple access' to realize multiple access for a large number of terminals.
A lively discussion was held with many questions about future IoT devices andtechnologies. We have a policy of this meeting to have enough time for discussion, andtherefore the question and response time was extended by 5 minutes at eachpresentation.
This workshop was a good place of information exchange that deepened theunderstanding about communications technology in the IoT space, and at the same time
meaningful comments from prominent professors in the mobile communication field
were received.
