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 highly mobile UMTS Level of Mobility "nomadic use" low to up to 2 Mbit/s) WLAN Bandwidth? high (up to 108 Mbit/s) Qatar 29 September 01 October 2003 7

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.
