DOCUMENT #: GSC13-GRSC6-15 FOR: Presentation SOURCE: ARIB (Toshihiro MANABE, NTT) AGENDA ITEM: GRSC6 4.2 CONTACT(S): ARIB Standards Development for Wireless Access systems Submission Date: July 1, 2008

2 Highlight of Current Activities (1)
4 working groups (including 3 technical working groups) have been constituted in ARIB-MMAC (Multimedia Mobile Access Communications System) Forum to make technical investigation, study on system specifications, liaison with other standardization bodies, promotion of demonstrative experiments and popularization activities. Promotion-WG Planning and managing promotion and popularization activities of the Forum MMAC WG Modification of ARIB STD-T71, incorporating introduction of high-speed wireless LAN in the 5GHz band Liaison with IEEE for updating ARIB STD-T71(TGn etc.) Maintaining the standard of ARIB STD-T71 and drafting its revisions UWB-WG Investigation of the discussion of interference mitigation function for UWB (Ultra Wide Band) system in Europe and Japan. Planning and promotion of UWB (Ultra Wide Band) demonstrative experiments. Provision of information regarding the investigation of interference mitigation function in Japan to ECC and ETSI. Exchange of information regarding the interference mitigation function among Asian countries. Maintaining the standard of ARIB STD-T91 and drafting its revisions. Establishment of residential backbone network sub-working group. mmWPAN-WG Study on standardization of millimeter-wave wireless PAN (Personal Area Network) Making a draft standard of millimeter- wave wireless PAN in Japan

3 Highlight of Current Activities (2)
MMAC WG activities Developing standards to define specifications for broadband mobile access communication system using CSMA Currently maintaining the ARIB STDs T66 and T71 T66 : for 2.4GHz systems (802.11b and g) T71 : for 4.9, 5.2, 5.3 and 5.6GHz systems (802.11j, 11a and 11n) Recently completed work: Following standards were revised in last year reflecting Japanese Radio Regulation change; ARIB STD T71 version 4.0 (May. 2007). Align with the 5.6GHz allocation for wireless LAN systems, technical requirements for the system using 5.6GHz band( GHz) were added Mitigation of limitation for 5.2 and 5.3GHz bands; inside traveling trains were assumed as indoor environment and use of 5.2 and 5.3GHz were permitted ARIB STD T71 version 5.0 (Dec. 2007). Technical requirements for channel-bonded 40MHz operation were added Liaison with IEEE for updating ARIB STD T71 Carefully watching the activities and directions of IEEE task groups; e.g. TGn(high-throughput) and TGs(mesh networking)

4 Strategic Direction ARIB standards development on Wireless LAN systems based on IEEE standards and Japanese Radio Regulations Contents of published IEEE standards should be reflected into ARIB STD T71 Reflection of draft phase standards (e.g. IEEE802.11n D.2.0) into ARIB STD T71 will be discussed and decided in MMAC WG Changes of Japanese Radio Regulations will be reflected into ARIB STD as soon as possible Modification of ARIB standards consider the certification programs of following industrial organizations; Wi-Fi Alliance Certification program that guarantees interoperability between wireless LAN access points and wireless terminals TELEC (Telecom Engineering Center) Certification that specified radio equipment conforms to the technical regulations based on the Radio Regulation of Japan

5 Challenges Due to the differences of standardization process, some gaps exist among their documents or (draft) standards Current version of ARIB STD-T71 is described based on Japanese Radio Regulation and it refers IEEE802.11n draft 2.0 standard IEEE TGn is revising the draft almost once two month and the latest version is 4.0 Wi-Fi Alliance has already started the IOT (Inter operability test) program based on IEEE802.11n draft 2.0 standard Differences and discrepancies among documents and standards mentioned above should be absorbed and new version of ARIB STD-T71 to be published No documents or standards exist regarding ad-hoc networking in MMAC WG To be discussed

6 Next Steps/Actions MMAC802.11WG to maintain ARIB STD-T71 and revise it align with activities of other standard bodies and industrial organization such as IEEE802.11, Wi-Fi Alliance and TELEC In MMAC, Wide Area Ubiquitous Network-WG (tentative name) will be newly constituted in 2008 Study on the wide area ubiquitous network system using many simple radio data terminals distributed over a wide area which perform data communications and information processing Development techniques for the wide area ubiquitous network
