The 1st Study Group Meeting on Private wireless communication- Started investigation and research aimed atadvancing private wireless communication technology -Private wireless communications systems are applied for various networks in many
fields; public fields such as national and local government, public infrastructure fields
such as electric power, gas and railway and general infrastructure fields such as landtransportation. In spite of their vital importance as social infrastructure, progress intechnology of private wireless communication is slow compared with public wirelesscommunication technology. Therefore, it has been decided that major players in private
wireless communication field, governments, manufacturers and users, meet together andinvestigate technology and user trends in Japan and oversees to improve the system.

5GMF to Conduct Integrated Verification Trial for 5G Mobile Communications

The Fifth Generation Mobile Communications Promotion Forum (hereinafterreferred to as “5GMF”), at its general assembly on 29 June 2015, decided to
conduct an integrated verification trial for the fifth generation mobile
communications systems (hereinafter referred to as “5G mobile”).
In the integrated verification trial, scheduled to commence in FY2017,
comprehensive experiments connecting the radio access, network and applications
will be performed toward the goal of commercializing 5G mobile in 2020.

The 5GMF (Chair: Professor Emeritus Susumu Yoshida, Kyoto University) wasestablished in September 2014 through the collaboration among industries, government
and academia, to conduct research & development, liaison and coordination with relatedorganizations as well as dissemination and enlightenment activities aimed at the early
realization of 5G mobile. Subsequently, four committees were set up within the 5GMF to
perform active deliberations. Based on the results of studies undertaken, the General
Assembly, at its 2nd session convened on 29 June 29 2015, approved a plan to conduct anintegrated verification trial on 5G mobile.
1. Aims of Integrated Verification Trial
To ensure smooth commercialization of 5G mobile in 2020, an integrated verification trial
connecting the radio access, network and applications will be launched in 2017.

After

starting with the evaluation on basic functions in the initial phase, the trial will progress
to evaluate 5G services in actual environments so that the views of application developers
and users can be reflected in line with the advancement of research and development
efforts. For the verification trial, an open environment that allows participation of
relevant parties, including enterprises and universities engaged in the R&D activities for
5G around the world, will be created in Japan to accelerate the global R&D andstandardization efforts, thereby contributing to the widespread adoption of 5G mobile.
2. Schedule Overview
A schedule overview is provided in Fig. 1. The testing environment will be preparedwithin FY2017, and the verification trial will commence thereafter. In the initial phase,the primary focus of the evaluations will be placed on the basic functions of radio andnetwork technologies, as well as the basic features centered on the radio/network
integration technologies. Utilizing these basic functions, the trial will advance further in
FY2019 to start evaluations in actual environments of various applications developed in
anticipation of the 2020 Tokyo Olympic/Paralympic Games and a wide range of other 5G
applications in new domains.
123. Spectrum to be used for Integrated Verification Trial
Both the lower frequency bands below 6GHz as well as higher bands such as centimeterand millimeter waves will be included in the scope of the verification trial. The specificfrequency bands to be used in the verification will be selected in the course of finalizing
the details of the system to be evaluated.
4. Members Participating in the Integrated Verification Trial
The trial will basically be open to participation by any enterprise or organization aroundthe world that agrees to the “Aims of Integrated Verification Trial” stated in Section 1
above. The 5GMF looks forward to having the participation of a broad range of parties,
including those engaged in the research and development activities promoted by the
Ministry of Internal Affairs and Communications, 5GMF members, and other carriers,
vendors or application developers, so that a comprehensive verification trial integrating
the radio access, network and applications can be conducted.
5. Venue
The trials are planned to be conducted in Tokyo (in view of the Tokyo Olympic/Paralympic
Games) and other local cities. Locations that can produce typical indoor and outdoor
environments in an urban setup will be selected in the future as the venue for the trial.
For instance, in the case of outdoor tests, vehicular areas, hot spots, open squares will besought, whereas in the case of indoor testing, locations like shopping malls and offices
will be considered.
