Build on existing standards. Whenever possible, WAP makes use of existing standards, thus not re-inventing the wheel. Where necessary, they make modifications to existing standards to make delivery to the unique interface limitations of wireless devices possible. For example, WAP is based on delivery of content using HTTP 1.1, just as is delivery of Web content to wired browsers. In many cases, a lighter, faster protocol that's more supportive of the bandwidth constraints of wireless has been developed by WAP to replace the wired version of the comparable protocol.
Wireless Constraints Developing content for wireless devices requires rethinking the Web experience.
Wireless devices tend to have very little real estate available for viewing content - often as small as 14x7 characters. Wireless devices also tend to be monochromatic, so images don't render well. There are no mice and the keyboards are difficult to use. Wireless devices tend to have limited CPU, memory, and battery life. Developers and designers need to find new, intuitive navigational techniques to overcome these constraints.
