Wireless Application Protocol (WAP) is emerging as a standard wireless protocol and browser framework for small, limited display capable devices. It is an Internet-enabling protocol, based on XML, allowing Internet access within cell phones, PDAs, and other low computational horsepower devices.

This paper discusses the uses and possibilities of WAP for embedded systems programmers. Topics include clients, servers, and proxies, web browsing on wireless Non-PCs, WAP architecture fundamentals, and an in-depth look at WML, the Wireless Markup Language.
