Real Challenge of Mobile Networks toward 5G: An Expectation for Antennas & Propagation
NameDr. Fumio Watanabe
AffiliationKDDI Research Inc., Japan

Biography :

Dr. Watanabe has 40 years of experience in research and development of satellite and mobile communication systems including IMT-2000, IMT-Advanced, WiMAX and 5G. He has been active for a long time in international standardization of mobile communication systems in ITU-R.

He received Piero Fanti International Prize in 1989, the R & D Awards of Radio Systems in 1991, the meritorious Awards on ITU activities in 2001, the Commendation for Science and Technology by the Minister of Education in 2010, and Maejima memorial Awards in 2013, respectively. He is the chairman of Broadband Wireless Access Committee in ARIB. He is a Fellow of IEIEC.

Abstract :

Mobile communication service is widely penetrating to all the society as the key infrastructure. It is spreading beyond the conventional telephone service. Wide variety of social services including e-commerce, e-bank, navigation, location, healthcare, and education are offered on the network. It's not too much to say that people can never part with a smartphone as the most frequently use interface between a human and society.

The next generation mobile system “5G” are under research, development and standardization for a service start of around year 2020. The conventional mobile systems have been designed mainly for human communications. On the other hand, 5G will cover wider range of usage scene. It sets a challenging goal to support not only ultra-high throughput, e.g. 10G bps, but also huge number of connectivity, and ultra-low latency, e.g. 1 ms radio access.

Frequency spectrums for 5G will be globally identified by WRC-19 and some of administrations will define the 5G bands before WRA-19 for early service launch. It is likely to use frequency bands higher than existing bands to have wider bandwidth for high throughput services. How efficiently use such high frequency, e.g. micro-wave and mm-wave, for mobile services is one of the key research & development topics in parallel to define “new radio access technologies”.

This talk will review the international standardization activities on 5G. It will cover technical issues on higher frequency bands applying mobile systems, and show two typical cases. First is a “spot” and the second is “beam antenna with multiple-site”. It will also include field system trials using 28GHz and images of 5G usage scene. They identify an expectation for antennas & propagation studies toward 5G.
