Topics

Current Spectrum Management

Future Changes on Spectrum Management

Particular Challenges

Supporting Growth in Wireless

Sharing experience




• 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




• 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




• unlicensed systems

• RLAN - 2400-2483.5 MHz (4W e.i.r.p.)

- 5725-5850 MHz (4W e.i.r.p.)

• Public Consultation (conditions may change)

5150-5350 MHz (200mW e.i.r.p.) +TPC+indoor

5250-5350 MHz (200mW e.i.r.p.) + DFS

5470-5725 MHz (1W e.i.r.p.) + DFS + TPC

5725-5850 MHz (Dig MOD) WRC-03




• Mobile Service

• 1996 – first regulation

800 MHz band (824-849/869-894MHz) - AMPS

(evolution – CDMA/TDMA)

• 1998 – privatization / new bands under study

• 2000 – new bands available (1700/1800/1900MHz)

• 2003 – harmonized solution

WLL(FS) = MS = IMT 2000 applic

Panorama

3 Main Mobile Groups

10 Regions

46 mil accesses (76% pre-paid + 24% pospaid) dec/03

teledensity ~26/100 inh (179 mil inh)

110 mil accesses Latin America ( ~42% Brazil) sep/03

faster growth than wireline service (MS x FS)





• 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)




• single regulation on spectrum use eficiency

• current bit/Hz

• regulation on spectrum usage conditions

• IMT 2000 applications

• DTV (channeling plan)



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

*MS 800MHz & 900MHz bands not represented

Challenges Faced by Agency - Refarming




• 450 MHz bands for MS

• opportunity to gap digital divide

• great number of analogue systems

• refarming/move current users

• spectrum use enforcement

• wide country – unauthorized stations transmitters – develop effort on radiomonitoring solution (investiment) & facilitate regularization



• 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

~32.5 mil stations nationwide





• need to provide regulation on new application/technologies

• need to provide neutral policies on spectrum use conditions regulation

• all technologies complies same regulation



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)



Rec & Practices from Brazilian Experience

relay on International Organization Recommendations onSpectrum and Treatments (from ITU-R, CITEL, MERCOSUL, IEEE, ETSI, ...)

public consultation before policy establishment

round-table between interested in spectrum use (industry, service providers, associations, citizens representatives, ...)

success on regulations characterized by

block arrangements, area licensed, unlicensed systems, scientifical trials.
