ARIB Standards Development for
Wireless Access systems
Submission Date:
July 1, 2008
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
– MMAC802.11-WG
• Modification of ARIB STD-T71, incorporating introduction of high-speed wireless LAN in the
5GHz band
• Liaison with IEEE802.11 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

Highlight of Current Activities (2)
•
MMAC802.11-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(5.47-5.725GHz) 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 802.11 for updating ARIB STD T71
– Carefully watching the activities and directions of IEEE 802.11 task groups; e.g.
TGn(high-throughput) and TGs(mesh networking)
3
Strategic Direction
• ARIB standards development on Wireless LAN systems based on
IEEE802.11 standards and Japanese Radio Regulations
– Contents of published IEEE802.11 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 MMAC802.11-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
4
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
– IEEE802.11 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
MMAC802.11-WG
– To be discussed
5
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
