occur with efficient inte- gration and inter-working of multiple technologies. During 2002-2003, more than 50% of terminals will be replaced ranging from low end to high end, with about 80% penetration of mobile users in some regions; today's smart- phones will be tomorrow's low end terminals. Thus, the minimum features for a UMTS handset at the start of 3G services will consist dual mode UMTS/GSM 900, 1800, 1900 MHz, including GPRS and HSCSD for seamless compatibility and roaming with 2G networks; 3 Satellite mobile services offering mainly voice and low data with world coverage. Service Components in UMTS integrated, WAP, Bluetooth; voice control and intelligent voice recognition (e.g. VoxML); large colour display and limited multimedia features; simultaneous UMTS sessions from 64 kbps up to 384 kbps; approx. 100 X 50 X 18 mm and <100 g; accessories - headset, camera, GPS and all existing accessories. Furthermore, information centric devices like PDAs will have additional options, e.g. advanced multimedia capabilities; video clip and play support with easy man-machine interface; video and music stream support; standard and open OS; WAP and Java application capabilities; HTML and XML browser, e-mail client, personal portal configuration capabilities; intelligent phone management features, e.g. cmd completion; advanced colour touch-screens; Bluetooth and all necessary features integrated, e.g. pull-able headset, camera, etc. 6.5.4.1 Applications Applications may not necessarily come from the technology design. However, the final blend will depend on the available and accessible technology. Therefore, the creation and implementation of applications will require large complicity between those provid- ing technology solutions, those generating application platforms (including SW), and those planning to offer services. For example, the quality and utilization feature of loca- tion services will not depend only on the information services server, but also on the capabilities of the terminal to display the information.
