    The next big challenge of the Internet is mobile access. More and more information is available on the Internet and intranets and mobile users will also need access to it. Wireless Application Protocol (WAP) based devices make it possible to access Wireless Markup Language (WML) based services with mobile browsers. The first WAP compliant devices have already been released on the market and more are to come. In the future there will be a need for Web services that are specially targeted for mobile users. We have studied this mobile-aware approach to service design by implementing a WML application and evaluating it on three different WAP platforms. Based on our evaluation results, we recognize challenges for future WAP devices and mobile-aware services. We have also studied if it would be possible to access the already existing Internet information with WAP devices. We have developed an HTML/WML conversion proxy server, which converts HTML-based Web contents automatically and on-line to WML. This approach gives the mobile users transparent access to their familiar Web pages from their mobile phones and other mobile devices. Our study indicates that if HTML-based Web services follow certain guidelines, they can be converted automatically to WML and adapted to the client device. In principle these guidelines already exist as World Wide Web Consortium (W3C) Content Accessibility Guidelines and W3C Note for HTML 4.0 Guidelines for Mobile Access.
