  • POLICY OBJECTIVES FOSTER COMPETITIVE AND

    INNOVATIVE COMMUNICATIONSINDUSTRIES

    MINIMIZE REGULATION AND ENACTFLEXIBLE REGULATORY POLICIES

    PROMOTE MARKET ACCESS ANDENCOURAGE GOVERNMENTS TO ADOPTOPEN, NON-DISCRIMINATORY,TRANSPARENT POLICIES

  • ITU-R JOINT TASK GROUP 1-6-8-9TERRESTRIAL WIRELESS

    INTERACTIVE MULTIMEDIA WRC-2003 AGENDA ITEM 1.21

    TO CONSIDER STUDIES CONCERNINGTECHNICAL AND REGULATORYREQUIREMENTS OF TERRESTRIALWIRELESS INTERACTIVE MULTIMEDIAAPPLICATIONS, IN ACCORDANCE WITHRESOLUTION 737 (WRC-2000), WITH A VIEWTO FACILITATING GLOBALHARMONIZATION

  • RESOLUTION 737 (WRC-2000)

    1. FACILITATE DEVELOPMENT OF COMMON,WORLDWIDE ALLOCATIONS ORIDENTIFICATION OF SPECTRUM

    2. REVIEW REGULATORY METHODS AND MEANSOF WORLDWIDE SPECTRUM IDENTIFICATIONTO FACILITATE HARMONIZATION OFEMERGING TERRESTRIAL WIRELESSINTERACTIVE MULTIMEDIA SYSTEMS FORUNIVERSAL PERSONAL SERVICES

    3. REVIEW, IF NECESSARY, SERVICEDEFINITIONS IN LIGHT OF CONVERGENCE

  • SPECTRUM MANAGEMENT(ITU-R SG 1) STUDIES

    HOW ARE INTERACTIVE MULTIMEDIAAPPLICATIONS OF TERRESTRIAL FIXED, MOBILE,AND BROADCASTING SERVICES CONVERGINGTECHNICALLY?

    HOW DOES TECHNICAL CONVERGENCE IMPACTON THE NATIONAL AND INTERNATIONAL RADIOREGULATORY ENVIRONMENT?

    IF TECHNICAL CONVERGENCE IMPACTS THESERVICE DEFINITIONS OF THE RADIOREGULATIONS, HOW SHOULD THE DEFINITIONS BEREVISED?

  • SPECTRUM MANAGEMENT(ITU-R SG 1) QUESTIONS

    WHAT CHARACTERISTICS DOES A TERRESTRIALWIRELESS INTERACTIVE MULTIMEDIA SYSTEMHAVE?

    WHAT ARE THE APPLICATIONS ANDTECHNOLOGIES THAT FALL INTO THISCATEGORY?

    HOW DO THESE APPLICATIONS ANDTECHNOLOGIES RELATE TO THE SPECTRUM?

    WHAT ARE THE SHARING SCENARIOS? WHAT ARE REGULATORY IMPEDIMENTS? WHAT ARE TRENDS (CURRENT AND FORESEEN)

    THAT WILL IMPACT THE RESPONSES TO THESEQUESTIONS?

  • BROADCAST (ITU-R SG 6)STUDIES

    STUDY GROUP 6 STUDIES TERRESTRIAL ANDSATELLITE BROADCASTING FROM END-TO-END, INCLUDING VISION, SOUND,MULTIMEDIA AND DATA SERVICESINTENDED FOR THE GENERAL PUBLIC. USEIS MADE OF POINT-TO-EVERYWHEREINFORMATION DELIVERY. WHEN RETURNCHANNELS ARE REQUIRED FOR ACCESSCONTROL, INTERACTIVITY, ETC., ANASYMMETRICAL INFRASTRUCTURE ISUSED.

  • MOBILE SERVICE STUDIESITU-R WORKING PARTY 8F

  • DIGITAL FM BROADCAST 88 - 108 MHz BAND EXISTING FM RADIO STATIONS IN THE U.S. ARE

    USING +/- 75 kHz DEVIATION AT 200 kHzCHANNEL SEPARATION

    SERVICES, EXCEPT FOR AERONAUTICAL MOBILESERVICE (AGAIN, INTERCONNECT MOBILESERVICE BASE STATIONS AND INTERCONNECTDIFFERENT SYSTEMS)

    65 - 71 GHz ALLOCATED TO INTERSATELLITESERVICE (ISS) TO MAKE SATELLITE NETWORKINTERCONNECTIONS MORE EFFICIENT (WILLPROMOTE VIDEO TELEPHONY, MEDICAL ANDTECHNICAL TELE-IMAGING, HIGH SPEED DATANETWORKS, AND BANDWIDTH-ON-DEMAND FORCONSUMERS)

  • U.S. UNLICENSED OPERATION57 - 64 GHz

    LICENSING THIS BAND IS UNNECESSARY BECAUSEOF THE VERY LIMITED POTENTIAL FORINTERFERENCE DUE TO THE LOW POWER LIMITS,THE DRAMATIC OXYGEN ABSORPTION OF RFENERGY AT FREQUENCIES AROUND 60 GHz, ANDTHE NARROW BEAMWIDTH OF POINT-TO-POINTANTENNAS USED OUTSIDE

    MAXIMUM PFD PERMITTED IN THIS 7 GHz BAND IS9 uW/cm2 AVERAGE, AND 18 uW/cm2 PEAK AT 3METERS

    NOKIA HAS ALREADY BEGUN DEPLOYINGUNLICENSED MICRO-CELLULAR EQUIPMENT INTHE BAND 57 - 59 GHz IN EUROPE

  • SOFTWARE DEFINED RADIO

    NEW TECHNOLOGY USING SOFTWARE (COMPUTERS), RATHERTHAN HARDWARE FOR TRANSMITTERS AND RECEIVERS TOCHANGE OPERATING PARAMETERS, INCLUDING FREQUENCY,MODULATION, AND POWER

    RADIOS QUICKLY CHANGE TRANSMIT FREQUENCIES ANDFORMAT

    DESIGNED TO ALLEVIATE POTENTIAL SPECTRUM SHORTAGEAND SPUR MORE EFFICIENT USE OF BANDWIDTH
