6 19 th 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? Qatar 29 September 01 October

7 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/ 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

8 volving AccessTechnologies UMTS/3G is vital for delivery of rich media! Due to the nature of the Technology, Licence conditions and Spectrum 2.5G might not fullfil the bandwidth requirements of some of the Data Services. WLAN WLAN GSM GSM GPRS GPRS Beyond 3G Access UMTS UMTS/3G TD-(S)CDMA W-CDMA HSDPA TDMA TDMA EDGE EDGE Qatar 29 September 01 October

24 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.
