i-mode Technology

i-mode is built on a firm foundation of advanced technology. The use of packet transmissions offers continuous access, while the use of a subset of HTML makes content creation easy and provides simple conversion of existing websites.

Compatibility

i-mode websites are created with iHTML, a subset of standard HTML. Since converting existing HTML websites to i-mode format requires only minor changes to the HTML, conversion is fast and easy, and the number of i-mode sites is high and increasing rapidly.

Efficiency

NTT DOCOMO's packet-switched technology was specifically designed to provide users with "always-on" network access, eliminating the need to log on or off. In turn, i-mode − the service developed for this packet-switched technology − provides the most efficient wireless access possible as no dedicated radio channel is required. The result is lower costs for customers as they are billed according to volume of data sent and received, rather than by time spent connected.

Versatility

i-mode offers one more significant benefit: mobile voice and data service in a single convenient package. This voice/data flexibility is unprecedented: people can download information about events, restaurants, etc., and then make reservations, or place calls to numbers searched in the i-mode directory.

Open Standards

At all phases of the development of i-mode, NTT DOCOMO pursued a policy of open technology exchange and joint large system tests at our R&D center with the world's leading research organizations, mobile communications operators and equipment manufacturers. In addition, i-mode supports Java-based applications whose importance continues to increase as the move to wireless devices accelerates globally.
