Mobile network protocols
WAP and I-Mode are the two major protocols or standards used today. WAP is mostly used in the US, and I-Mode is popular in Japan and Europe.
Sites must often be designed separately for different protocols. The Adobe image tag does not need to be customized for each protocol.
|WAP 1.0||WAP 1.0 is quickly losing popularity in the US. This required pages be built in WML, and had its own protocol.|
|WAP 2.0||Most phones are WAP 2.0 compliant, meaning they support XHTML MP (a mobile version of XHTML).|
I-Mode supports CHTML (compact HTML) and does not download third-party images. First-party collection domain implementations should always be used with I-Mode sites so images are downloaded.
