1ARIB Standards Development for Wireless Access
systems
Submission DateJuly 1, 2008
2Highlight 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
3Highlight 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)
4Strategic 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
5Challenges
- 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
6Next 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
