• In Japan, three mobile carriers have invested a total of \15.1 trillion in facilities over 10 years,

resulting in 100-percent population coverage for 3G.

• The present LTE population coverage rate in Japan is over 90% (March 2014)

Reference: 86% in the U.S. (December 2012) , 26% in EU (December 2012).

Requirements for 5G

◆ Requirements of 5G

○ High Data Speed and Ultra Low Latency,

comparable to wire connections

○ Multiple Simultaneous Connections

in sensor networks

<Key Properties>

✓ Peak Data Rate ≥ 10Gbps

（100 x current LTE rate）

*under certain circumstances could reach 20Gbps

✓ Connection density ≥ 1M connections/ km2

（100 x current LTE）

✓latency ≤ 1 millisecond （1/10 of current LTE）

✓ System Capacity ≥ 10Mbps/m²

（1,000 x current LTE）

✓ Low power consumption （Energy Efficiency）

✓ Effective Use of Spectrum Efficiency

5 The New world towards implementation of 5G

Ex：Quick transmission

of high definition TV

(4K/8K) Main Properties

of 5G

✓ 5G will not only feature high speed data transmission through maximizing existing technology but also

will require the preparation of a new network for ultra low latency and multiple simultaneous connections

✓ 5G will connect everyday objects to the internet, becoming the foundation of the Internet of Things

Promotion Forum Activities

Missions (examples) Giving strategic guidance on R&Ds, standardization, international cooperation & public relations

R&Ds on 5G through Industry-Academic-

Government Cooperation

Investigation into potential spectrum for 5G through R&D activities

Amend regulations, allocating Spectrum,

deploy base stations, etc.

Propose & Evaluate Interface

5G Applications for new fields ○ ITS, Medical, Health, Beauty, Elder Care,

Security, Resilience, Signage, Energy,

Agriculture, Education

○ To support the Tokyo Olympics/Paralympics

✓ The 5G mobile Integrated Trial to test radio access, networks, and applications for 5G will be started

in Japan in FY2017 with the cooperation of industry, academia, and the government.

✓ Promote further research and development and standards for 5G through building an open trial

environment which stakeholders from global enterprises and universities can participate.
