Nokia is now demonstrating an XHTML microbrowser on a standard mobile phone. The new browser is shown running on the modified Nokia 6210 and Nokia 7190 handsets. The demonstration is meant to show that important advances in consumer services can be made very quickly and implemented in real-world phone designs. Nokia plans to start incorporating the browser in its handsets by the end of this year. Nokia’s WAP service delivery platforms are already designed to enable access to XML-based languages such as XHTML. The server infrastructure will be ready for testing with XHTML-handset later this year, and future releases of service delivery platforms will be deployed in time for commercial roll-outs of XHTML-based services. As is the case with Nokia’s current WAP browser, Nokia will license the browser source code to other handset manufacturers, mobile phone operators, service providers, and others. Licensing information is available from The new software will support current WAP content, WML, as well as the new XHTML standard, ensuring both backward compatibility and next generation services. In addition, the software is designed to be extendable, so that its functionality can grow along with the capabilities coming in GPRS networks and new phone hardware designs. The demonstration also shows the use of cascading style sheets and a new rendering engine, which together enable a GUI for content delivery. This GUI, a standard feature in the wired world, will significantly improve usability for consumers and convenience for operators. The style sheets themselves are a major advantage, as they will make it possible to easily tailor content specifically to different handsets. Nokia will collaborate with a number of companies on XHTML application technology and content creation tools. The first XHTML developer’s kit from Nokia will be available this summer.
