The imode is the NTT DoCoMo's new Internet access system. It is an advanced intelligent messaging service for digital mobile phones and other mobile terminals that will allow you to see Internet content in special text format on special imode-enabled mobile phones. Enabling information access from handheld devices requires a deep understanding of both technical and market issues that are unique to the wireless environment. The imode specification was developed by the industry's best minds to address these issues. Wireless devices represent the ultimate constrained computing device with limited CPU, memory and battery life and a simple user interface.Wireless networks are constrained by low bandwidth, high latency and unpredictable availability and stability. The imode specification addresses these issues by using the best of existing standards and developing new extensions when needed.
The imode solution leverages the tremendous investment in web servers, web development tools, web programmers and web applications while solving the unique problems associated with the wireless domain.

WORKING OF IMODE
Imode uses the proprietary PDC-P packet-switching protocol for data transmission over the existing circuit-switched PDC voice network. This provides an “always on” service for both push and pulls transmissions. The use of packet switching is appropriate for data transmission because a communication path is not dedicated to a data call, thus enabling resources to be shared between many users.
Imode works basically the same as the any typical software HTML browser allowing users to access thousands of Imode enabled web sites via WWW address, simply by pushing the cell phone’s “I-Mode”button.When you select an Imode item in the handset menu, the data is usually immediately downloaded. There is no delay for dialing up the connection after a click on a link or a type in a URL and press the remote or enter button.
