This work was carried out in the research project "WML Browser" of VTT Information Technology between March 1999 and April 2000. The main goal of the project was to build a software that is capable of browsing WML (Wireless Markup Language) and emulating different WAP (Wireless Application Protocol) terminals, and allows the WML developer to build and edit WML documents by using visual components. Also, the project group decided to use the existing technologies and well-defined specifications and open standards as much as possible. The developed software was named Visual WML. WAP architecture enables the interconnection of the wireless data network and the wired data network, and WAP technology brings the Internet content and advanced data services to digital cellular phones and other wireless devices. At the same time, the variety of different kinds of mobile terminals and networks are increasing. For instance, the forthcoming mobile communication channels will increase the transmission capacity, and wireless local area networks will offer fast and easy access to wired internet, corporate and home environment LANs and their services. Hence, in particular, tools for WAP application development are required. Visual WML is a tool targeted for editing, creating and browsing WML documents. It is also possible to emulate different kinds of WAP devices by utilizing User Agent Profiles.
