2. 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 2

3. Highlight of Current Activities (2) 3 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  Develop 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.

4. Strategic Direction  Further studies of technical specifications of the WAUN system towards 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.  The technical and operational requirements will be discussed in ITU-R SG5 WP5A. 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
