INTERNATIONAL TELECOMMUNICATION UNION Workshop on Radio Spectrum Management for a Converging World Geneva — ITU New Initiatives Programme — 16-18 February 2004
¾ Current Spectrum Management • spectrum regulation establishes usage conditions (technical, coordination, sharing condition, band use) • channeling plan & block arrangements • systems must be certified • certification process - Agency, DCB and TestLab - Mutual Recognition Agreement
INTERNATIONAL TELECOMMUNICATION UNION Workshop on Radio Spectrum Management for a Converging World Geneva — ITU New Initiatives Programme — 16-18 February 2004
¾ Current Spectrum Management • unlicensed systems • restrict radiation device License-exempt station operation System certification by Agency or Accredited Lab need • regulation applies short range devices (cordless phone, keyless, RLAN – DIG MOD) • spectrum use on secondary basis

¾ Current Spectrum Management – Mobile Service ¾ Panorama ¾ 3 Main Mobile Groups ¾ 10 Regions ¾ 46 mil accesses (76% pre-paid + 24% pospaid) dec/03 ¾ teledensity ~26/100 inh (179 mil inh) ¾ 110 mil accesses Latin America ( ~42% Brazil) sep/03 ¾ faster growth than wireline service (MS x FS)
INTERNATIONAL TELECOMMUNICATION UNION Workshop on Radio Spectrum Management for a Converging World Geneva — ITU New Initiatives Programme — 16-18 February 2004
¾ Future Changes on Spectrum Management • trends on Regulation • block arrangements x channeling plan • area licensed (MS, LMDS 28GHz, MMDS 2GHz) • previous coordination between players sharing spectrum • frequency leased under trade agreement between players (under study)
INTERNATIONAL TELECOMMUNICATION UNION Workshop on Radio Spectrum Management for a Converging World Geneva — ITU New Initiatives Programme — 16-18 February 2004
¾ Future Changes on Spectrum Management • single regulation on spectrum use eficiency • current bit/Hz • regulation on spectrum usage conditions • IMT 2000 applications • DTV (channeling plan)
INTERNATIONAL TELECOMMUNICATION UNION Workshop on Radio Spectrum Management for a Converging World Geneva — ITU New Initiatives Programme — 16-18 February 2004
¾ Challenges Faced by Agency
• MS & IMT 2000 bands required refarming • 450 MHz bands for MS • spectrum use enforcement • need to fast provide regulation on new application/technologies • need to provide neutral policies on spectrum use conditions regulation

¾ Challenges Faced by Agency • Helth afect non-ionization radiation • citizens worried claiming for policies • agency provided existing regulation • supported by international consultation • addopted ICNIRP limits for SAR • JUL/2003 – 50% stations evaluted • JUL/2004 – last 50% evalution concluded ¾ ~32.5 mil stations nationwide
INTERNATIONAL TELECOMMUNICATION UNION Workshop on Radio Spectrum Management for a Converging World Geneva — ITU New Initiatives Programme — 16-18 February 2004
¾ Challenges Faced by Agency
• need to provide regulation on new application/technologies • need to provide neutral policies on spectrum use conditions regulation • all technologies complies same regulation

¾ Spur Growth in Wireless Service • radio frequency systems provides fast mean to increase competition • FS-WLL, Pay-TV (MMDS), PMP 3.5/10.5GHz (data access) • spectrum for unlicensed use • authorization for scientifical trial spectrum use • brought up new applications (38GHz PMP systems, DTV)
INTERNATIONAL TELECOMMUNICATION UNION Workshop on Radio Spectrum Management for a Converging World Geneva — ITU New Initiatives Programme — 16-18 February 2004
¾ Rec & Practices from Brazilian Experience ¾ relay on International Organization Recommendations on Spectrum and Treatments (from ITU-R, CITEL, MERCOSUL, IEEE, ETSI, ...) ¾ public consultation before policy establishment ¾ round-table between interested in spectrum use (industry, service providers, associations, citizens representatives, ...) ¾ success on regulations characterized by ¾ block arrangements, area licensed, unlicensed systems, scientifical trials.
