Highlight of Current Activities (1)

Broadband Wireless Access (BWA) Sub-committee consists of four working groups in ARIB. They mainly assume a role in producing national standards for WiMAX, Next Generation PHS and IEEE802.20 referring to relevant international standards.

International Relations WGTo establish coordination framework with relevant international standardization bodies

WiMAX WGTo develop and maintain ARIB standard for mobile WiMAX system and to liaise with relevant international standard bodies

Next Generation PHS WGTo develop and maintain ARIB standard for Next Generation PHS system and to liaise with relevant international standardization body

(note: PHS MOU Group has changed its name to XGP, eXtended Global Platform in April 2009, however, there is no influence on the naming of “Next Generation PHS” in ARIB at present.)

802.20 WGTo develop and maintain ARIB standard for IEEE802.20 TDD Wideband and 625k-MC Modes and to liaise with relevant international standardization body


Highlight of Current Activities (2)

Development of standardsStandards consist of national regulatory requirements specified in MIC Ordinance Regulating Radio Equipment and international technical requirements standardized by international standard bodies.Three standards were produced under the following titles.

STD-T94 OFDMA Broadband Mobile Wireless Access System (WiMAX applied in Japan), in December 2007STD-T95 OFDMA Broadband Wireless Access System (Next Generation PHS), in December 2007STD-T97 Mobile Broadband Wireless Access Systems (IEEE 802.20 TDD Wideband and 625k-MC Modes Application in Japan), in September 2008

Liaison with International standardization organizationsARIB established the liaisons with the following organizations on reproducing or their standards into ARIB standards.

WiMAX Forum and IEEE802.16 WG for WiMAX standardXGP (former PHS MOU Group) for Next Generation PHS standardIEEE 802.20 WG for IEEE 802.20 standard


Strategic Direction

ARIB standards are developed in line with international standards as much as possible and the national regulatory requirements are incorporated into the standards as mandatory requirements.In case of inconsistency between national requirements and international standards, the national requirements are to be incorporated into the international Standards. The national requirements prevail, however, if the inconsistency is not resolved.ARIB agrees with relevant international standard organizations on reproducing their standard documents into ARIB standards under the following conditions.

International standard documents are reproduced to ARIB standard on an as is basis.ARIB is allowed to copy and distribute the standards through its website or by photocopy.International standard organizations disclaims all warranties in relation to use of their documents.


Challenges

As for WiMAX standard there is a need to compile international standards since they were developed by two different organizations. IEEE802.16 defines PHY and MAC layer specifications, while WiMAX Forum works on profiling the IEEE802.16 specifications and developing the upper layer network architecture.

Reproduction of IEEE documents in ARIB standard is subject to consent made between ARIB and IEEE.

ARIB needs to follow future updates of international standard documents and to revise ARIB standards accordingly.


Next Steps/Actions (1)

ARIB standards STD-T94, STD-T95 and STD-T97 are maintained and updated in the event that the referenced international standards are modified. Following modifications are planned to be implemented:

STD-T94Revise “Mobile System Profile” release 1.0 to release1.5Revise “End-to-End Network Systems Architecture” release 1.1 to release 1.5 Add “Mobile Radio Specification”

STD-T95Revise STD-T95 based on the modification planned by XGP

STD-T97Add “802.20.2 Protocol Implementation Conformance Statements”Add “802.20.3 Minimum Performance Specifications”Amend the “802.20 Management Information Base” chapterAdd information on Standard 802.1Q-2005 amendment for bridging 802.20 MAC


Mobile WiMAX Pilot LaunchPilot Launch - 2/26/2009

UQ Communications launches its pilot service on February 26th, 2009.The service covers Central Tokyo and Vicinity where about 10% of Japan's overall population reside (Japan population: 127Million).About 6,000 Pilot users enjoy free pilot service until the end of June.

WiMAX DevicesUQ prepares data cards and WiMAX/Wi-Fi CPE for pilot users in order to accelerate the adaption.

Speed and QualityThe measured throughput on the general speed test site reaches: Download 16Mbps, Upload 3Mbps. There still are some areas where WiMAX is not available. UQ is building base stations to fill the gap.

UQ WiMAX Data Cards



Mobile WiMAX Commercial ServiceCommercial Launch - 7/1/2009

UQ Communications launches its commercial service on July 1st, 2009.The service coverage is expanded to Greater Tokyo and other biggest cities (Osaka, Kyoto, Kobe, Nagoya) where about 20% of Japan's overall population reside (Japan population: 127Million).UQ provides flat rate monthly access at 4,480JPY without any long term contract.

A variety of WiMAX DevicesA variety of WiMAX embedded laptop, data cards and CPEs are expected to be sold as operator-free devicesSubscribers can select any WiMAX operator including MVNOs after the device purchase .

MVNOsThe WiMAX network is open to MVNOs, and many MVNOs start its services.

BWA Subcommittee

Scope of Work The BWA Subcommittee has been established so as to study technologies on broadband wireless access (BWA) systems and standardize their technical specifications as ARIB Standards. Current target systems are broadband wireless access systems in the 2.5 GHz band of which technical conditions have been studied by Telecommunications Council.

Technologies under StudyMobile WiMAX (based on IEEE 802.16-2004 Standard amended by 802.16e-2005)Mobile Broadband Wireless Access (based on IEEE 802.20 Standard) - Wideband Mode - 625k-MC Mode Next-Generation PHS (based on XGP (former PHS MoU Group) Standard)
