Super-GEO Proposals
- Regional
- One or two highly complex satellites in GSO
- Multiple spot beam coverage
- Transparent transponder / Digital filtering
SLIDE 32
Implementation (1)
When is this all going to happen? - Very soon! · First generation systems due for launch
before 2000. Next generation systems by 2010
SLIDE 33
Implementation (2)
Iridium
- First partial plane due about 2 weeks ago (launch postponed 3 times - will happen very
soon now!)
- Following testing and concept proving, full constellation will be deployed over next
couple of years.
- BUT service only fully viable once entire constellation deployed.
Notes:
Note that Globalstar plans to start launching in 1997. ICO not sure... but likely to be in the
same timeframe.

Implementation (3)
Super-GEOs
- Still fighting for spectrum!
- First systems should be launched in 1998-2000 timeframe
- System is viable from first launch - key advantage of Super-GEO!
SLIDE 35
The future...
-Follow-on systems already on the drawing board
- FPLMTS / IMT-2000
- UMTS
- integration with UPT
-Movement towards "Global Bandwidth on Demand" rather than simple cell phone
replacement.
SLIDE 36
Conclusions
- Personal Communications Networks are being implemented now as S-PCNs
- Will provide all (most?) features of the "Personal Communicator"
- Network developments being driven by demand for bandwidth
- Potential to replace entire fixed network World-wide!
