  1. Japan’s Innovative Wireless Technology Presented by: Jennifer Milosch

  2. What is iMode? • The name of a wireless internet service for cell phones • Created in Japan by NTT DoCoMo in February ‘99 • iMode is more successful than other wireless technologies because of its low costs and quick and reliable internet access • At first only available in Japan, now also in Europe • Not available in the US at this time

  3. What is NTT DoCoMo? • The largest mobile communications company in Japan • Started making mobile phones in 1993 Created W-CDMA technology • In 2000, changed the corporate name to NTT DoCoMo and prepared for the release of the iMode phones President and CEO Masao Nakamura

  4. iMode Users • Summer 2004: 42 million users in Japan, and 4 million elsewhere • Approximately 1/3 of Japanese have an iMode phone • Popular among all ages and genders, but slightly more above 40 years old

  5. What’s So Special About It? • “Smart” handset • 100 MHz processor • Color display with a graphical user interface (GUI) • Users can browse the web by pressing a button

  6. What’s So Special About It? • New transmission protocol: • iMode uses the CDMA protocol • This transmits at 9.6K bps, slower than a normal modem, but faster than other types of wireless connections for phones • The speed allows for emails limited to 250 characters and simple graphics

  7. What’s So Special About It? • New markup language: • iMode uses C-HTML (Compact HTML) as its markup language, instead of WAP • C-HTML is a special markup language to display web pages on the smaller display screen of a cell phone • C-HTML websites can be viewed on PCs

  8. Packet Switching • iMode uses packet switching technology to transmit data • Data is broken apart into individual parts • Smaller packets are sent over many different switches • The data is reassembled at its destination • Efficient for networks with heavy traffic, such as the internet • The connection is not kept continuously open

  9. iMode Functions • News, weather and traffic • Stock prices • Email: Text and pictures • Online shopping and banking • 160+ financial institutions have iMode pages • Games http://www.imode.net.tw/index.asp

  10. Well It Must Cost a Fortune! • iMode service is only $2.70 per month plus .26 cents per packet • Downloads purchased at $.85-$2.00 per month • DoCoMo receives commissions from its first tier providers

  11. DoCoMo’s Business Strategy • Keep costs low • Investment in R&D • Heavy investing abroad • Buys 15-20% stakes in companies which use DoCoMo technology • Hutchison Whampoa, Dutch KPN Mobile, AT&T Wireless, etc.

  12. Mobile Options Panasonic’s P502i NEC’s N502i • Many mobile providers have iMode compatible phones Sony’s SO502i Sharp’s SH821i

  13. Comparison of iMode Phones

  14. iMode’s Competition: WAP • WAP (Wireless Application Protocol) uses WML and existing websites • More advanced than the iMode technology • WAP is the similar technology in the US • Many hope the two will merge • http://www.imperium.co.uk/wapdesign.html 9110 Communicator Nokia 7110

  15. Why is iMode better than WAP? • WAP handsets usually only black and white • WAP only supports text, not graphics • iMode is much faster and easier to use • iMode is simpler, and the C-HTML language is better understood • WAP users must use dial-up

  16. 3G: The Future of iMode • Launched in October 2001 • Starting speeds of 64 bps • Able to support videos, Mp3s, videophone, and videomail • Uses W-CDMA • Able to hold larger files • New lithium-ion batteries
