Radio Access - Three Main Phases
New radio interface(s)
i.e. research target 100 – 1000 Mbit/s (full to low
mobility)
Relationship with other radio systems
e.g. Digital broadcast, RLAN, etc.
Enhancing IMT-2000
e.g. “fast packet” up to
30 Mbit/s by 2005 ?

Spectrum
• Prerequisite for development and operation
of radio systems is the availability of spectrum
• Most of the usable spectrum is already allocated
•Decisions on global spectrum allocations/identification
are taken at ITU World Radiocommunication Conferences
• There is a long lead-time between identification
of spectrum and spectrum availability

Resolution 802 (WRC-03)
2007 World Radiocommunication Conference
Agenda item 1.4
“to consider frequency-related matters for the
future development of IMT-2000 and systems
beyond IMT-2000, taking into account the results
of ITU-R studies in accordance with
Resolution 228 (Rev.WRC-03)”
Resolution 228 (Rev.WRC-03)
resolves
1
to further study technical and operational issues …;
2
to report to WRC-07 on the spectrum requirements and potential
frequency ranges …;
3
to conduct regulatory and technical studies on the usage of
frequencies below those identified for IMT-2000 …;
4
to take into consideration the particular needs of developing countries
including use of the satellite component of IMT-2000 …;
5
to include sharing and compatibility studies with services already
having allocations in potential spectrum …;
6
that WRC-07 should consider frequency-related matters for the
future development of IMT-2000 and systems beyond IMT-2000 …,

Summary
• IMT is being implemented and will evolve considerably
over next 10-15 years - an open and market led process
• Mobile, Internet and broadband access is growing
rapidly
• Convergence is occuring in many spheres
• New radio interface(s) are expected to be required
sometime between 2010-2015
• Spectrum aspects will be considered at WRC-07
- WP 8F is leading the preparatory studies
