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?

Is 4G a radio umbrella technology or a standalone technology or is ita 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

ConclusionsConclusionsOperators are committed to providingthe viability of mobile data before lauching3G services. Smooth migration as a corner stone ofsuccessful 2.5G and 3G deployment.In the search of services that drive up revenues per user, UMTS is vital fordelivery of rich media.Operators need to start thinking of IMS Business Cases and Network Interconnectivity now.
