5G Commercialization and Future Change

Dr. Hongbeom Jeon

5thgeneration mobile communication systems abbreviated as 5G is known to have such characteristics as enhanced Mobile Broadband, Ultra Reliable Low Latency Communication, and Massive Machine Type Communication. A number of global telecom operators and manufacturers have been trying to specify the relevant standards, develop systems and devices, and test the feasibility of various services and applications through field trials worldwide for several years. Quite a few leading initiatives and pilots have proved that 5G can provide not just a lot higher data rate over 1Gbps to conventional smart phones but also new types of mission critical communication services essential to, for example, autonomous driving vehicles, factory automation, drone surveillance, etc. That’s why 5G is viewed as the basic infrastructure for 4th industrial revolution, in which industrial productivities can be enhanced much higher thanks to new technologies such as virtual reality, artificial intelligence, autonomous systems.

KT has been exercised leadership in 5G technologies and services since it announced 5G vision since MWC 2015 and has also demonstrated 5G networks and services successfully to the world in the last Pyeongchang Olympic. Based upon the experiences and know-hows learned from the impressive massive pilot, it has kept moving forward for the ambitious plan to launch world-first 5G commercial services in the market by the first quarter of 2019, issuing commercial specs, testing and procuring the necessary equipment, acquiring spectrums for deploying 5G network, and developing applications and business models.

In this presentation, I’m going to talk about what will be the true impact of 5G to the future life and what KT has been doing to realize the potential value to its maximum in more detail, and also going to tell you what kind of changes we can see in very near future when 5G services are commercialized finally.

Next Steps in Antennas and Propagation for Implantable Biosensors and Systems

William G. Scanlon

It has been more than two decades since the first published work on UHF antennas for medical implants and there has been a steady increase in commercialization of medical biosensors and systems. Despite significant efforts, one of the most challenging problems facing medical bioelectronics (micro/nanosystems, actuators and sensors) remains the physical device size. This is generally a concern, but it is particularly important for applications where one or more elements of the bioelectronics system is implanted within the patient’s body. There is also an interest in injectable (minimally invasive) devices and while biocompatibility is readily achievable, biodegradability remains a holy grail that would make a transformative impact on medical applications.At the same time, advances in mixed signal ASIC technology and micro/nano interfaces including biophotonics for sensing and therapeutics are gathering pace, but there are sticky challenges remaining for the miniaturization of energy harvesting, storage and transfer and communication, especially in the context of generalized applications where tissue characteristics, implantation depth and positioning are not known or not well controlled. This presentation will set out these challenges and consider the antennas and propagation aspects of this problem and will present some recent work on tissue-independent antennas, electrically small implant antenna efficiency and implant to body surface communication links.

Toward Actualization of 5G by Co-Cleation with a Wide Range of Vertical Industries

Dr. Yukihiko Okumura

The fifth-generation mobile communications 5G is a next generation system having features such as enhanced mobile broadband, massive machine type communications, and ultra-reliable low-latency communications, which further developed the existing system. International standardization work is ongoing to specify 5G specifications in 2017-2018 and we DOCOMO are shifting to development phase from research phase toward actualization of 5G commercial system.
On the other hand, 5G is currently becoming one of the hot topics of not only the mobile communication field but also the whole industry and academia using ICT. 5G system trials are ongoing for many kinds of use cases in Japan and other countries, and those are unexampled large scale trials through former generations of mobile communication systems. This situation can be understood as proof of very high expectation for 5G system by potential customers and players of very widely areas.
This talk will describeDOCOMO’s view on the key technologies of 5G system, various new applications and services expected to be provided by 5G, and migration scenarios of 5G network.In addition, the talk will introduce DOCOMO’s latest activities toco-cleate 5G services, including field experiments and system trials in cooperation with a wide range of vertical industries.
