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

4. REPORT TO A FUTURE CONFERENCE

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?
