  2. Presentation Outline • The i-mode History - i-mode services- Basic Features of i-mode- i-mode structure and architecture- i-mode Experience and Lessons- Advantages and Disadvantages- Comparisons of i-mode and WAP- Challenges and Future of i-mode

  3. The I-mode History • i-mode was developed by DoCoMo ( which means “anywhere” in Japanese) a telecommunication service provider Nippon Telegraph and Telephone Corp.) in 1992. • i-mode (The “i” stands for information) is a wireless technology. • The i-mode service, begun in Feb. 1999, enable users to access Internet services via their cellular i-mode phones.

Advantages

  10. Disadvantages:- • i-Mode service and technology is currently only available in Japan. • i-Mode is not an entirely open protocol. That limits the drive the developers can make for this technology. Disadvantages

  11. WAP in Europe has been deployed on a circuit-switched network. • i-Mode in Japan has been deployed on a packet-switched network. • i-Mode users enjoys almost-instant downloads and the response times needed for online gaming with their "always-on" network. i-Mode vs. WAP - Network
