th Century perception of
19th
year 2003
Uncertainties:
- In customer willingness to buy into new
services.
- On the demand for broadband mobility.
- As to who will be the actors in the value
chain.
- As to how to simulate the demand.
- Will access to content prevail over
connectivity?

Conclusions
Operators need to think of their current
Installed data base and how they will offer
them a 3G service within an extended EC
Market.
Smooth migration as a corner stone of
successful 2.5G and 3G deployment.
In the search of services that drive up
revenues per user, UMTS is the broadband
platform, vital for delivery of rich media.
Consideration should be given to their
current investments in transition towards
Network innovation.
