Symbian

Symbian is an independent joint venture supported by companies including Ericsson, Nokia, Motorola and Psion. Symbian aims to prom ot6 a mass market for mobile information devices in two ways:

First, through the development of core software, application frameworks, applications and dev6lopment tools for mobil6 multimedia devices (such as PDA s, smart phones and communicators)

Second, by "evangelizing" standards for the inter operation of mobile information devices. Symbian's EPOC operating system is already available and Ericsson devices such as the R380 are EPOC-enabled.

WAP

Wireless Application Protocol (WAP) is a global, open standard that gives mobile users acc6ss to Intern 6t services through handheld devices. It 6nables us6rs to easily access a whole range of Mobile Internet and other data services from mobile devices such as smart phones and communicators, and without the need to plug into a separate laptop or data-enabled device.

WAP enables this through a built-in "WAP micro browser" that lets information be accessed direct from a phone, in the same way that web browsers provide access to on-line services via an Internet-ready PC. Typically, a WAP screen will display a number of hyperlinks to various services or information portals.

As well as WAP phones, Ericsson has also announced a WAP Service Developer's Kit ( WapIDE) and the WAP Gateway/ Proxy, which bridges WAP applications and services in Internet and intranet environments with mobile networks. In addition, Ericsson provides application enablers, such as Ericsson Localized Internet (ELI) for location-based services, and WAP Application Server (WAS) providing a run-time and development environment for WAP applications.

Ericsson is one of the four founding members of the WAP Forum. Since 1997, when it was established, the WAP Forum has gained widespread industry support - hundreds of companies are members of the worldwide WAP Forum- The latest version of the WAP standard, WAP 1.2. 1, has recently been launched.

Our dedicated WAP constants are ready to assist operators and service providers sharpen their competitive edge. They help today's businesses adapt to the new economy and create cost-effective, innovative ways to communicate with customers.
