2 doc.: IEEE /245r0 Submission March 2003 Y.Inoue, NTT Slide 2 MMAC Overview MMAC (Multimedia Mobile Access Communication Systems Promotion Council) –An organization in the ARIB (Association of Radio Industries and Businesses). –Activities: Investigation and study on system specifications Demonstrative experiment Information exchange and popularization activities, etc –Working Groups High Speed Wireless Access 5GHz Mobile Access (Wireless Access and Wireless LAN) Wireless Home-Link (Wireless 1394)

3 doc.: IEEE /245r0 Submission March 2003 Y.Inoue, NTT Slide 3 T71 Ad hoc Working Group ARIB STD-T71 –Technical requirements and specifications for IEEE a systems to operate in Japan. –T71 Ad hoc WG has been created to revise the current ARIB STD-T71 to incorporate the technical requirements for 5GHz Band Wireless Access systems. Chair: Mr. Noboru Matsumoto, SpeedNet Member companies: Atheros, Canon, Denso, Fujitsu, Hitach Cable, Intel, Japan Telecom, JRC, Mitsubishi, Murata, NEC, NTT, TOYOCOM, Panasonic, Samsung, SpeedNet, TDK, Toshiba, TTNet, and more Supposed to finish its work by the end of March

Technical Requirement –Frequency Plan & Channelization –Radio Equipment Ordinance Article 49-21: (5GHz Band Wireless Access Systems) 20MHz/channel, 10MHz/channel, 5MHz/channel Transmit power, Spectrum mask, Spurious emission, etc Open Issue –Channel Numbering Method Currently, we have 1 proposal. But not adopted in the draft. T71 Ad hoc strongly hope to have the same mechanism with TGj. Chair of T71 Ad hoc sent an to ask for review of TGj draft.

6 doc.: IEEE /245r0 Submission March 2003 Y.Inoue, NTT Slide 6 Schedule Mar./19/: The 3rd (and final) meeting of the T71 Ad hoc WG. –The draft will be approved by the WG. Discussions by if necessary.
