Century perception of
year 2000
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?

Avoid the Hype!
Is 4G a radio umbrella technology or a standalone technology or is it
a network?
What are the services?
Real time over WLAN, but no real time properties (802.11a/b/g)?
WLAN/WiFi/802.11 “Treat” to UMTS/3G!
Deployment for IPv6 and Mobile IPv6:
-First with reconnect strategy when roaming
-Then Mobile IPv6 always-on-anytime roaming

– Fixed and mobile access
to the same service
portfolio.
– Quick and easy service
roll-out.
Reduction of Total Cost of
Ownership
– Single network technology
– Low Maintenance cost.
– Minimal cost for O&M.
– Reduced leased-line.

Operator Benefits:
Outperforming User Expectations
Convergence of CS and PS domain services (incl VoPacket)
Interoperability with other access systems (e.g. fixed)
Reducing Total Cost of Ownership
Simple network structure
Flexible allocation of functions to network elements
Common transport and control platforms, respectively
Reduction of complexity, spare part management, etc.

Conclusions
Operators are committed to providing
the viability of mobile data before lauching
3G services.
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 vital for
delivery of rich media.
Operators need to start thinking of
IMS Business Cases and Network
Interconnectivity now.
