A microbrowser technology that supports text, graphics, audio, and video for Web access over the Japanese cellular network. In consideration of the inherently limited bandwidth of the cellular network, i-Mode employs Compact HTML (C-HTML), a simplified version of HTML similar to Wireless Markup Language (WML) used in WAP networks. Transmission between the handhelds and the i-Mode-enabled cell sites is via packet mode, using packets of 128 octets, at rates up to 9.6 kbps. i-Mode is a proprietary service developed by NTT DoCoMo, initially for the Japanese market. See also browser, cellular radio, octet, packet, WAP, and WML.
