  1. Global Standards Collaboration (GSC) 14 ARIB Standards Development for Broadband Wireless Access systems Kohei SATOH Managing Director, ARIB

  2. Highlight of Current Activities(1) • Broadband Wireless Access (BWA) Sub-committee consists offour working groups in ARIB. They mainly assume a role inproducing national standards for WiMAX, Next Generation PHS and IEEE802.20 referring to relevant international standards. • International Relations WG • To establish coordination framework with relevant international standardization bodies • WiMAX WG • To develop and maintain ARIB standard for mobile WiMAX system and to liaise with relevant international standard bodies • Next Generation PHS WG • To 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 WG • To develop and maintain ARIB standard for IEEE802.20 TDD Wideband and 625k-MC Modes and to liaise with relevant international standardization body

  3. Highlight of Current Activities(2) • Development of standards • Standards 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 2007 • STD-T95 OFDMA Broadband Wireless Access System (Next Generation PHS), in December 2007 • STD-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 organizations • ARIB established the liaisons with the following organizations on reproducing or their standards into ARIB standards. • WiMAX Forum and IEEE802.16 WG for WiMAX standard • XGP (former PHS MOU Group) for Next Generation PHS standard • IEEE 802.20 WG for IEEE 802.20 standard

  4. 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.

  5. 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.

  6. 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-T94 • Revise “Mobile System Profile” release 1.0 to release1.5 • Revise “End-to-End Network Systems Architecture” release 1.1 to release 1.5 • Add “Mobile Radio Specification” • STD-T95 • Revise STD-T95 based on the modification planned by XGP • STD-T97 • Add “802.20.2 Protocol Implementation Conformance Statements” • Add “802.20.3 Minimum Performance Specifications” • Amend the “802.20 Management Information Base” chapter • Add information on Standard 802.1Q-2005 amendment for bridging 802.20 MAC

  7. Next Steps/Actions (2) Mobile WiMAX Pilot Launch • Pilot 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 Devices • UQ prepares data cards and WiMAX/Wi-Fi CPE for pilot users in order to accelerate the adaption. • Speed and Quality • The 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 Wi-Fi Gateway UQ WiMAX Data Cards

  8. Next Steps/Actions (3) Mobile WiMAX Commercial Service • Commercial 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 Devices • A variety of WiMAX embedded laptop, data cards and CPEs are expected to be sold as operator-free devices • Subscribers can select any WiMAX operator including MVNOs after the device purchase . • MVNOs • The WiMAX network is open to MVNOs, and many MVNOs start its services.

Advanced Wireless Communications Study Committee (Effective on April 1, 2006) Steering Committee IMT PartnershipSubcommittee IMT-Advanced Subcommittee BWA Subcommittee Advanced Wireless Communications Study Committee (ADWICS) of ARIB - To conduct technical studies on IMT-2000,IMT-Advanced and Broadband Wireless Access (BWA) - To contribute to the global standardization Objectives - Study on Technical Aspects of above three areas - Prepare for Standard Proposals - Contribute to Standardization at ITU - Take Cooperation with Standardization Bodies Overseas Missions

  12. 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 Study • Mobile 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) BWA Subcommittee International Relations WG Next-Generation PHS WG WiMAX WG 802.20 WG
