  9. 3G using IP Only Pros ? IMTC Fall Forum – November 2002 – New York, NY, USA

  10. The suite of application that works well • Wireless Imaging (JPEG Cam) • MP3 Streaming • MMS (Multimedia Messaging) • Presence • GPS / Location-Based Services • Multi-Party Games • E-Banking • Internet Common Services: Email, Web, Chat, etc. IP Pros: Non Delay-Sensitive Applications IMTC Fall Forum – November 2002 – New York, NY, USA

  11. Conversational multimedia and video streaming needs fixed delay which IP V4 can not assure • IP V4 addressing scheme is too limited for mass market mobile use • IP V6 can address delay-sensitive and addressing requirements but… • When? Who will pay? ROI? • Long deployment paths: Interoperability, OSS • IPv6 addressing scheme worldwide definition/actual deployment • Complete IPv6 networks. Hybrid of IPv4 & IPv6 = QoS of IPv4 IP Cons : Delay Sensitive Applications IMTC Fall Forum – November 2002 – New York, NY, USA
