ARIB Standards Development for Wireless Access systems

ARIB(Osamu Kagami, NTT)

Global Standards Collaboration (GSC) GSC-15 1

Highlight of Current Activities (1) 5 working groups (including 4 technical working groups) have been

constituted in MMAC Forum to make technical investigation, study on system specifications, liaison with other standardization bodies, promotion of demonstrative experiments and popularization activities.

1. Promotion-WG Planning and managing promotion and popularization activities of the Forum

2. MMAC802.11-WG (ARIB STD-T71) Study on the high throughput WLANs (> 1Gbps) that are under development in IEEE 802.11

TGac and TGad Liaison with IEEE802.11 for updating ARIB STD-T71(TGn etc.)

3. UWB-WG (ARIB STD-T91) Investigation of interference mitigation function for UWB system in Europe and Japan Experimental test of the propagation of UWB system considering real environments Exchange of information regarding the interference mitigation function among Asian

countries

4. mmWPAN-WG Study on standardization of millimeter-wave wireless PAN Making a draft standard of millimeter- wave wireless PAN in Japan

5.Wide Area Ubiquitous Network (WAUN) -WG Study on the WAUN system

• Motivational research of sensor and/or actuator communications• Studies of system requirements and technical specifications of the

system• Contribution to the allocation of the radio frequency spectrum for

the system Developing a standard of the WAUN system

• What’s the WAUN system? It is the large cell-based public mobile wireless access system for

sensor and actuator communications. It supports a variety of service applications that handle small amounts

of data at comparatively long intervals such as automation and efficiency enhancement of business works, environment observation, remote control of plant facilities and social security.

Strategic Direction Further studies of technical specifications of the WAUN

system toward a development of the ARIB standard • Air interface to keep communication capacity, quality and security

that are suitable for sensor and/or actuator communications• Technologies to provide economical communication services with

simple, small and inexpensive wireless terminal

Activities toward the global harmonization• Establishment of ITU-R recommendation/report

New question was already set up as Question ITU-R 250/5.

• Investigation of the similar activities and directions in other standardization bodies and countries

IoT (Internet of Things) project in China SUN (Smart Utility Network) in IEEE802.15.4g Smart Grid, Smart metering (ETSI TC M2M), etc.

4

Challenges Wide Area Ubiquitous Network-WG will contribute towards

Making ITU-R recommendation/report on: the technical and operational requirements, and the feasibility studies of sensor and/or actuator communications.

Developing fundamental technical documents for: the frequency allocation for WAUN system in Japan, and the revision of Japanese Radio Regulations.

5

Next Steps/Actions Wide Area Ubiquitous Network-WG

• Studies on technical specifications of WAUN system• Development of ARIB standard in FY2012
