About the wireless Web


    Web sites designed for wireless viewing are made with markup languages designed for the wireless internet.The following languages are available for wireless:

    • Extensible Hypertext Markup Language (XHTML-Basic and XHTML-Mobile) is the XHTML specification for wireless, and alternative mobile and untethered devices. XHTML is the standard for 2.5G and 3G (third generation) devices.
    • Multimedia Messaging Services, or MMS, is based on Synchronized Multimedia Integration Language (SMIL). SMIL is an XML-compliant markup language that lets you lay out and synchronize multiple streaming and static media tracks in a multimedia presentation for MMS-compatible portable devices. 2.5G and 3G devices support MMS.
    • Compact Hypertext Markup Language (cHTML), or i-HTML (trademarked as i-mode) is a special subset of the HTML 2.0, HTML 3.2, and HTML 4.0 specifications, commonly known by the NTT DoCoMo trademark i-mode. I-mode (also known as iHTML) is the default standard for 2.5G devices that support i-mode networks.
    • Wireless Markup Language (WML) is a tag-based standard based on XML and used by 2G (second generation) devices.

    Sites authored with these languages are in increasing use throughout the world. If your mobile telephone service provider offers wireless browsing, you can visit Web sites created in these languages.

    Developing a successful wireless Web site requires working within special constraints. Many users pay additional fees for Web browsing on their mobile telephones and handheld computers. You need to design your site so that text, images and navigation are optimized for small screens and file size is optimized for minimal download times.
