Openwave is continuing its leadership and innovation in the wireless Internet space by defining for our customers the evolution to 2.5G and 3G services, said Don Listwin, president and CEO of Openwave. We are especially pleased to pioneer 3G wireless Internet services with KDDI in Japan. Our new technologies support the broad range of advanced Japanese content and services.
Openwaves products are a critical part of our strategy to bring third generation wireless multimedia services to KDDI subscribers in Japan, said Tadashi Onodera, executive vice president at KDDI. Openwave offers us the critical mass of technology and rapid time to market needed to get innovative services up and running quickly.
The next version of WAP enables the convergence of the WAP specifications and the broader Internet. By taking advantage of enhancements in mobile devices and networks, the WAP 2.0 architecture supports XHTML, TCP and HTTP. Use of XHTML, the next generation of HTML from the W3C, will enable web developers to create applications in a single markup language, for delivery to PC and WAP browsers. These technologies are expected to be in the market in 2001.
