CANNES, France--(BUSINESS WIRE)--Feb. 20, 2002

Citrix Systems, Inc. (Nasdaq:CTXS), a global leader in virtual workplace software and services, today announced that it has obtained validation from the Nokia OK program for the Citrix(R) Independent Computing Architecture (ICA(R)) Client for the Symbian platform. Nokia (NYSE:NOK), a world leader in mobile communications, applied stringent testing standards to Citrix ICA technology, which allows users to wirelessly access Windows(R), UNIX(R) and Java(TM) applications on Nokia's 9200 Series Communicator mobile devices.

As the core technology behind Citrix MetaFrame(R) application serving software and Citrix NFuse(TM) application portal software, ICA enables organizations to deploy Windows, UNIX and Java applications across enterprise networks regardless of user location, client hardware or available bandwidth.

The features offered by the Citrix ICA Client for the Nokia 9200 Communicator Series include international keyboard support, client drive mapping, and panning and scaling for navigating PC form factor applications on the device monitor.

Many of the attributes of the Nokia 9200 Communicator Series, aimed at mobile professionals, reflect the direction in which the wireless communications industry is heading. These features include a high-resolution color display, high-speed mobile e-mail, a new user interface and multimedia capabilities such as full-color video clips.

"Companies today need to build a productive, mobile workforce by allowing employees to access information without being slowed down by traditional bandwidth limitations," said Roger Baskerville, director, Embedded Systems, EMEA, for Citrix. "Using the Citrix ICA Client with technology from Nokia, businesses can offer their employees the freedom to work remotely by providing wireless access to the server-based applications and information they need to perform their jobs."

The Citrix ICA Client for the Symbian platform is currently available as a download from the Web at http://www.citrix.com/download.

About Citrix ICA

Citrix Independent Computing Architecture (ICA) is an emerging industry standard for server-based computing. Citrix ICA technology includes a server software component, a network protocol component, and a client software component. ICA separates application logic, which executes 100 percent on the server, from the user interface. This allows efficient, server-based application installation, management, deployment and support. The ICA network protocol transports keystrokes, mouse clicks and screen updates over standard protocols to the client, typically consuming only 10-15 kilobits-per-second of network bandwidth. ICA client software, which supports virtually any device or platform, lets users view and work with the interface as if the application were running locally.
