BlackBerry Enterprise Server to Gain New Corporate Data Access Features

Mobile Data Service Feature Of BlackBerry Enterprise Server To Extend Corporate Data Access Beyond Email

Waterloo, ON - At the Wireless Enterprise Symposium in Atlanta today, Research In Motion Limited (RIM) (Nasdaq: RIMM; TSE: RIM) announced plans to add new corporate data access features to BlackBerry Enterprise Server. Building on the secure, extensible and robust architecture of the existing, award-winning BlackBerry™ solution, RIM plans to introduce a new BlackBerry Enterprise Server feature called Mobile Data Service.

BlackBerry has already been recognized and embraced by thousands of organizations as the leading wireless email solution for corporate and government sectors. The new Mobile Data Service feature (which is currently in Beta trials) of BlackBerry Enterprise Server is designed to provide ISVs and in-house corporate developers with an environment that supports additional wireless corporate data access and interaction capabilities beyond email. Mobile Data Service works in conjunction with the BlackBerry browser (which supports standard Internet Protocol based content and connectivity to BlackBerry Enterprise Server) and the BlackBerry Development Environment for Java (including standard J2ME API support) to provide an optimized platform for mobile applications running on advanced wireless, packet-data networks.

Mobile Data Service and the overall BlackBerry infrastructure will enable device connectivity via standard protocols and languages while maintaining the solid architectural components that allowed BlackBerry to succeed with thousands of companies that wanted a secure, manageable and complete wireless email solution behind their firewall. BlackBerry customers can leverage the existing, approved BlackBerry architecture and security model to deploy reliable, secure, end-to-end applications without any additional infrastructure to learn or support. Mobile Data Service maintains the key characteristics of existing BlackBerry deployments including end-to-end security (with Triple DES encryption), data push capabilities, multi-network support and centralized management.

"Our early decision to build an enterprise-class wireless email solution paved the way for today's announcement of the new Mobile Data Service features of BlackBerry Enterprise Server. While email is certainly unique in its near ubiquitous adoption within corporate environments, email shares many of the same technical and administrative requirements of other wireless enterprise data applications including security, manageability and integration," said Mike Lazaridis, President and Co-CEO at Research In Motion. "We purposely built BlackBerry on an open, extensible platform that satisfies the rigorous demands of Fortune 1000 companies. As a result, we are well positioned to enable email and corporate data access services through a single architecture that provides the industry's best solution for both users and IT departments."

Mobile Data Service is another important element of RIM's open strategy for BlackBerry and adds continuing momentum following the introduction of the BlackBerry 5800™ Series and the BlackBerry Development Environment for Java. Mobile Data Service offers increased flexibility and opportunities for enterprise customers, developers and carriers. Enterprise customers can extend the strategic and productivity benefits of BlackBerry beyond voice and email services. ISVs and in-house corporate developers can leverage the pre-existing wireless network access and expedite their application development while eliminating the overhead and complexities associated with acquiring and managing connections into multiple wireless networks. Carriers benefit from the ability to offer advanced wireless data services that take advantage of new packet-data networks and help acquire and retain enterprise customers.

Key Features of Mobile Data Service:

Standard Protocol Connectivity - Mobile Data Service provides standards-based connectivity via the BlackBerry infrastructure including support for HTTP, TCP/IP and UDP protocols. This minimizes the need for developers to learn or apply new connectivity techniques and allows new or existing corporate applications to be easily extended to BlackBerry handhelds.

Standard Language Support - Mobile Data Service is designed with efficient native language support for XML, WML and cHTML and also supports the use of plug-in transcoders for other languages. By utilizing the standard mark-up languages for client interaction, Mobile Data Service reduces the need for customization when creating content for display and interaction on BlackBerry handhelds.

High Data Security - As part of BlackBerry Enterprise Server, Mobile Data Service leverages the same highly secure BlackBerry architecture that is available for wireless email. Only devices authenticated to a BlackBerry Enterprise Server may access the Mobile Data Service feature and corporate data is exchanged via the same (Triple DES) encrypted connection between the handheld and the server behind the corporate firewall. As a result, Mobile Data Service leverages an industry-leading solution and security model provided by BlackBerry Enterprise Server that is widely accepted.

Data Push Support - Mobile Data Service supports the ability to push information to BlackBerry handhelds. Push capability and "always on" handhelds are fundamental to supporting wireless enterprise applications. Information is delivered to the handheld as it becomes available rather than waiting for the user to initiate data exchange and download.

Multi-Network Support - As part of BlackBerry Enterprise Server, Mobile Data Service supports multiple wireless networks and BlackBerry handhelds. BlackBerry Enterprise Server, equipped with Mobile Data Service, can support an organization's entire wireless corporate data access needs through a single, consistent architecture and simplify the deployment and management of wireless data applications.

BlackBerry Browser - The BlackBerry browser is dual-purposed allowing it to securely access corporate data via Mobile Data Service as well as carrier content services and gateways. The BlackBerry browser supports standard WML, HTML and XML based content and HTTP/HTTPS connectivity to BlackBerry Enterprise Server. With Mobile Data Service and the BlackBerry browser, customers are provided with the front-end and back-end tools necessary for wireless enterprise applications.

RIM is previewing Mobile Data Service features at the Wireless Enterprise Symposium this week. Further information regarding features, specifications and commercial availability of Mobile Data Service will be announced at a later date.
