Millimeter-Wave Wireless Access Network Project
-Application to 5G Heterogeneous Cellular Networks-
Makoto Ando (Executive Vice-President for Research Tokyo Inst. of Tech.)

The overview of the Millimeter-Wave Project 2007-2016 (founded by Ministry of Internal affairs and Communications, Japan) will be presented. It demonstrates 1) 6.1Gbps mmWave access at 60GHz band between a smartphone terminal and a small-cell BS, 2) 60GHz compact range communication system using a 32x32 array to provide enhanced communication area up to 15m and 3) 40GHz outdoor system with full-duplex capability 2x1Gbps to enhance the spectral efficiency. The concept of mmWave integrated 5G heterogeneous networks (HetNet) using 40 and 60GHz bands are demonstrated.
In the demonstration, pedestrian users experience off-loading from Wifi (5GHz) to 60GHz and download a big files when passing through the series of GATEs.

5G Core Technologies
Organizers :  Yukihiko Okumura (NTT DOCOMO, INC.)
Chair :  Seichi Sanpei (Osaka Univ.)

Fifth-generation mobile communications system, 5G, is required to accommodate a drastic traffic increment expected in future advancement and diversity of wireless services.
In this session, representative research members will present the progress and outcomes of "The research and development projects for realization of the fifth-generation mobile communications system" which are promoting by The Ministry of Internal Affairs and Communications, Japan, from 2015.

H [ Basic, Introductory, and Elementary Microwave Courses ]

WE2B  Tutorial

Nov. 30 (水)  14:00-16:00   Room 2 (Annex Hall F203)
Introduction to Digital Modulation and Signal Analyses
Organizer / Chair :  Masayuki Kimishima (Advantest Lab. Ltd.)

The analysis techniques of the quadrature modulation-demodulation for digital wireless communications are presented. Based on Fourier transform, it is modeled by simple mathematics and illustrated the behavior. Then, by introducing the RC-polyphase filter and the Hilbert transform, the relationship between them and the quadrature modulation-demodulation is considered.
Finally, as an example of the application, the behavior of the modulator with IQ imbalances which is one of significant problem in the wide-band wireless communications is shown, and it leads to how to decide the stimuli and analyze the responses from the circuit under test.

WE3B  Tutorial

Nov. 30 (水)  14:00-16:00   Room 3 (Annex Hall F204)
Basic Lecture of Transmission Line Design for High Speed, High Frequency Applications
Organizers :  Masayuki Kimishima (Advantest Lab. Ltd.)
Chair :  Masayuki Nakajima (Murata Manufacturing Co.,Ltd.)

When the transfer data rate exceeds 1Gbit/s, the signal quality is degraded by increasing of transmission line loss. These losses are explained as the effect on signal quality. And the techniques to get wider eye patterns, are presented. In addition, a theoretical analysis of the differential cross-talk is presented as functions of line length, circuit constant and PCB layer structure.

WE4B  Workshop

Nov. 30 (水)  14:00-16:00   Room 4 (Annex Hall F205)
Wireless Power Transfer and Its Estimation Technologies of Electromagnetic Compatibility
Organizer / Chair :  Naoki Shinohara (Kyoto Univ.)

Research and development of wireless power transfer (WPT) technologies are presently accelerated in the world. For further R&D, commercialization, and industrialization, electromagnetic compatibility of the WPT and impact study to conventional wireless system is required and important. The WPT is roughly considered as two technologies, inductive coupling/resonance coupling WPT in kHz-MHz band and WPT in far field via UHF . microwave.
In this session, all WPT technologies are included.

Recent Trends and Issues of Wireless Systems in the Fields of the Manufacturing and Mining Industries
Organizers :  Kenichi Maruhashi (NEC Corp.), Yoshinori Kogami (Utsunomiya Univ.)
Chair :  Ken Takei (Hitachi, Ltd.)

The fields of factories and mines are tough environments for wireless communications. There are large obstacle objects for radio propagation, legacy wireless terminals attached to old manufacturing and construction machines, noises from machines, a large number of mobile terminals in a closed space, and coexistence of a variety of wireless systems and so on. These are issues to be carefully considered to deploy wireless systems in the fields. In the future, more wireless devices such as sensors, RFID tags, and monitoring systems are expected to be introduced to enhance productivity in the above environment. But what is a barrier for that?
In this workshop, based on "real data" obtained from the fields, technologies required for wireless terminals and systems and efforts to realize them in factories and mines will be discussed.
