11. Concluding Remarks
The 12th scientific workshop held in Tohoku University was the last one in theseries of the 22nd URSI-C in Japan. Actually 22nd term first round was held in
Tohoku University, and finally became the Tohoku again. In addition, the theme of
the first round was disaster immediately after the Great East Japan Earthquake, andthe theme of the workshop also became disaster associated with assistance forreconstruction. Every one of the participants had been feeling the change of Sendai
during this period.
Prior to the lecture, we joined a tour of the state of the propagation
measurement experiment and radio relay demonstration using unmanned aircraft by
the National Institute of Information and Communications Technology this time.
In the lecture, we had the following presentations:•Aircraft-to-Ground Radio Channel Measurement for Unmanned Aircraft
Systems (UAS) by Dr. Takizawa•Delay tolerant message delivery system using UAS by Dr. Takeuchi•Wireless bridge system and relay-by-smartphone system using small UAS
by Dr. Nishiyama•Reliability Improvement of UAS Space-Time coding Wireless Relay
by Prof. Adachi資料8-CThe night session, in which was noted was also held. And we have received alecture by Mr. Nishi about the current state of applications using unmanned aircraft inrecent years of the United States, the developed countries of unmanned aircraft.
Thus, with increasing attention of the use of unmanned aircraft in the future, a
lively discussion for a variety of wireless communication technologies related tounmanned aircraft and the tour of the radio relay experiments using unmanned aircraft
were carried out. I think meaningful information has been obtained to all participants.
