5G mobile networks can offer high-speed data transmission, low-latency data transfer and effective connection to many terminals, by the use of wideband radio spectra. Various types of transmission media including optical fibers, millimeter-wave links and THz links will be required to provide high-speed and low-latency wireless transmission for many terminals. To mitigate congestion of radio spectrum, traffic over microwave bands should be minimized by using seamless networks where waveforms for radio services to connect end-users are transferred over optical fibers, millimeter-waves, THz-waves, etc. This presentation describes recent research trends on the seamless networks comprised of high-speed wireless and wired links, as well as on sensing applications such as high-resolution radars for airport surveillance.

Tetsuya Kawanishi received the B.E., M.E., and Ph.D. degrees in electronics from Kyoto University, Kyoto, Japan, in 1992, 1994, and 1997, respectively. From 1994 to 1995, he was with the Production Engineering Laboratory of Panasonic. During 1997, he was with the Venture Business Laboratory, Kyoto University, Kyoto, Japan, where he was engaged in research on electromagnetic scattering and near-field optics. In 1998, he joined the Communications Research Laboratory, Ministry of Posts and Telecommunications (now the National Institute of Information and Communications Technology), Tokyo, Japan. During 2004, he was a Visiting Scholar with the Department of Electrical and Computer Engineering, University of California at San Diego, San Diego, CA, USA. Since April 2015, he has been a Professor with Waseda University, Tokyo, Japan. His current research interests include high-speed optical modulators and RF photonics. He is the TG-FWS (task group on fixed wireless systems) in AWG (Asia Pacific telecommunity wireless group).
