Citrix ICA to Deliver Full-Function Access to Business Applications on

Next-Generation Mobile Devices

Citrix Systems Inc., (Nasdaq:CTXS) a global leader in application server software and services, today announced it is strengthening support for wireless information access with a new Citrix(R) Independent Computing Architecture (ICA(R)) Client for Symbian. The Symbian platform, which is a fully open, flexible and complete operating system for next-generation Wireless Information Devices (WID), has been adopted by many leading manufacturers, including Ericsson, Kenwood, Matsushita, Motorola, Nokia, Philips, Psion, Sanyo, Sony and Siemens. At CeBIT, Citrix will demonstrate the new ICA Client with the Nokia 9210 Communicator, one of the upcoming mobile information devices that run on the Symbian Platform, on Stand B07 in Hall 3.

The Citrix ICA Client for the Symbian Platform, which will be available later this year, provides high-performance access to mission-critical applications and information on next-generation Symbian-based WIDs. The Citrix application serving model, which installs, manages and processes applications on central servers and provides high-performance access on virtually any device using ICA, eliminates the need to develop special versions of applications for WIDs of different sizes and configurations. The Citrix approach also enables wireless users to access Web content via ICA without the limitations imposed by small form factors.

"In today's increasingly mobile workplace, businesses are continually looking for the best ways to extend the reach of their IT investments to employees on the move," said Jeremy Copp, vice president of Business Relationships at Symbian. "The Citrix ICA Client for the Symbian platform opens up real-time wireless access to a huge variety of existing and future business applications. Organizations can now quickly and effectively push applications and data to Symbian-based devices over all generations of networks."

"Demand is growing rapidly for mobile devices that combine voice communication with full application-access and data-manipulation capabilities," said Keith Turnbull, vice president, Product Development for Citrix. "Symbian's new platform is an emerging standard in this space that has been adopted by many of the industry's leading players. The addition of Citrix application serving capability to Symbian-based devices will be compelling for organizations looking to quickly and easily extend business-critical applications to workers on the move."

The upcoming Citrix ICA Client for the Symbian Platform will allow users of the latest mobile computing devices to experience the same level of performance from Windows(R), UNIX(R) and Java(TM) applications as they would from their desktops. As a result, organizations using Symbian-based devices will be able to rapidly provide mission-critical applications beyond the enterprise to workers on the move, on any network, anywhere in the world.

The Symbian Platform is optimized for a wide range of Smartphones and Communicators, delivering integrated mobile phone technology with Bluetooth, email, SMS, WAP, HTML and other messaging and browsing capabilities to suit all types of end users. It provides powerful and robust services including the multi-tasking kernel, data management, communications, graphics, multimedia, security, application engines, Java runtime environment, and support for data synchronization and worldwide locations.

About Citrix ICA

With more than 24 million users worldwide and 6 million concurrent user licenses since its introduction in 1995, Citrix Independent Computing Architecture (ICA) is an industry standard for server-based computing. Citrix ICA technology includes a server software component, a network protocol component, and a client software component. On the server, ICA separates application logic from the user interface and executes 100% of the application on the server. The ICA network protocol transports keystrokes, mouse clicks and screen updates over standard protocols to the client, typically consuming less than 5 kilobits-per-second of network bandwidth. On the client, users see and work only with the application's interface.
