6. 6 How do we take them there? 4 Networks - today’s networks are data capable. Operators need to start there migration today to keep up with the future network demands of tomorrow. Through an evolution of: 4 Applications - internet, location based services and transaction based applications over WAP will drive demand 4 Markets - operators need to determine what type of role they want to play in wireless data and what market segments to go after

14. 14 Summary It’s critical that we do not get consumed by the technology but stay focused on the END-USER needs DoCoMo has shown us all that the issue is not access but providing key marketable applications to the end-user Even with all the efforts of the OHG there are still at least 3 distinct paths in supporting an evolution to IMT - 2000 l Existing cdmaOne operators should deploy a 1XRTT solution migrating to 3G3X (CDMA2000) l Existing GSM operators will migrate to GPRS/EDGE migrating to UMTS through the purchase of new spectrum l Existing TDMA operators will follow a similar path as GSM stopping at EDGE Bottom line is that migration to a digital wireless network should begin “TODAY” regardless of the access network that you are operating
