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
MMAC: Multimedia Mobile Access Communications System
mmWPAN: Millimeter-wave Wireless Personal Area Network

Highlight of Current Activities (2)
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.
3
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

What is MMAC?
Objective

To realize MMAC (Multimedia Mobile Access Communication
Systems) through investigations of system specifications,
demonstrative experiment, information exchange and
popularization activities and thereby contribute to the efficient
use of radio frequency spectrum.
