A SEMINAR PRESENTATION ON“I-mode TECHNOLOGY” SUBMITTED BY:- Naresh Kumar Nagar ECE 4thYear SUBMITTED TO:- Mr. Ravi Gupta
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
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.
The i-mode Services • Voice communications • A large number of sites can be accessed simply pressing the i-mode key. • Useful in mobile commerce services:- • mobile banking • stock trading • ticket reservations. • Application downloads from more than 1600 web sites.
The Basic Features of i-mode • i-mode 2G service has a transmission speed of 9.6 kbps. • i-mode has the packet-switching system. • i-mode uses SSL (Secure Socket Layer). • i-mode uses Sun Solaris servers on the back end. • i-mode uses Compact HTML (C-HTML) and proprietary protocol stack. • i-mode provides an always on service no dial is needed.
Connecting to sites, receiving messages and transmitting e-mail are done via the DoCoMo i-mode center. i-mode Structure
Japan marketed i-Mode as an experience not a technology • Targeted to consumers • Large, readable screens COLOR • Phone enables (email,animations, etc.) • Lots of content sites: 500+ official, 15K+ unofficial content provider sites. i-mode Success
Advantages: • i-Mode technology does not require special language for the mobile unit. • i-Mode is accessible by a packet-switched network, meaning that users are always online. • i-Mode users are charged only for the amount of information downloaded to the i-Mode unit, not the time they spend at the web sites. Advantages
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
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
WAP in Europe uses text and no images small screen. • i-Mode in Japan uses text and color images and larger screen. • WAP is Marketed for business application (banking, stock portfolio, business news, flight booking). • i-Mode marketed for consumer applications (restaurant guide, fun images, ringing melodies). i-Mode vs. WAP - Deployed Applications
