Citrix Teams With Sierra Wireless for Access to Rich Applications Over GSM and GPRS Networks.

Business Editors/High-Tech Writers

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

Citrix Systems, Inc. (Nasdaq:CTXS) today announced it has strengthened its relationship with Sierra Wireless to allow real-time wireless access to rich applications over GSM and GPRS networks. Together, Citrix and Sierra offer no-compromise wireless access to corporate information for today's mobile professional. Citrix(R) MetaFrame(R) application server software enables secure and manageable access to applications by employees in the field on PDAs, notebooks, or other mobile devices, while the new Sierra Wireless AirCard(R) 750, a tri-band wireless network card for the PC slot, allows this data to be accessed wirelessly. This solution gives mobile workers access to any of their business applications, in effect creating a virtual workplace wherever they are.

The AirCard 750 seamlessly connects to GSM or GPRS networks so there is no need to dial-up - providing the ability for an always-on service that can be used worldwide. The AirCard 750 offers a high overall throughput potential, handling data at speeds up to 56 kbps, depending on the service provider, making it an ideal choice for fast data transfers via Citrix MetaFrame servers. The 750 also receives notification and simultaneously handles SMS (Short Message Service) messages and GPRS data transfers. Citrix's Independent Computing Architecture (ICA(R)) enables secure access to all office applications, including ERP, CRM and other line of business applications, on a large number of devices with excellent performance. The ICA protocol only transfers screen updates and keystrokes, bringing additional security to the air interface through encryption and authentication, and consumes as little as 5-20 kpbs of network bandwidth. This enables even large files to be accessed with exceptional performance on wireless devices.

"Employees are increasingly demanding seamless real-time access to their applications and information over next-generation wireless networks," said Roger Baskerville, director embedded systems, EMEA, Citrix. "The combination of the high-throughput Sierra Wireless AirCard 750 and Citrix's latency reduction feature improves the user experience by reducing perceived delay over today's GPRS networks."

Citrix MetaFrame software can already be used with the Sierra Wireless AirCard 300, 510, and 555 wireless network cards, and support for the new AirCard 750 GSM/GPRS card demonstrates the two companies' joint commitment to enabling enterprise mobility. Citrix and Sierra Wireless are both members of the Sierra Wireless WirelessReady(TM) Alliance (WRA), and Sierra Wireless is a Premier-level member of the Citrix Business Alliance(TM) (CBA).

"We are delighted to be working closely with Citrix to deliver on the vision of a virtual workplace - allowing freedom and mobility for employees," said Mark McMillan, vice president of marketing, Sierra Wireless. "The two solutions are complementary for enterprises wishing to take advantage of GSM and GPRS networks."
