th 19th 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

Efficiency of Spectrum Usage
W-CDMA and TD-SCDMA handle mixed voice and data services most efficiently. Max capacity available for every service mix. No Call drops. No restrictions on Access capacity of one service for other users.

Unified Multimedia Network Rational
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. Most advanced technology

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.
