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 6 Supplementary Slides 7 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.
