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. Today the most common navigational technique on wireless is the list with drill-down capabilities. More likely, wireless users are expected use their devices to execute small, specific tasks that they can take care of quickly, such as finding the time a movie's showing, purchasing a CD, looking up sports scores or stock prices, etc. Content developers need to develop with these motives in mind. Rather than having to develop their own tools for converting content into the myriad standards that device manufacturers might develop, they can be assured that all WAP-compliant tools and gateway software will work with all others.
