BASE Launches BlackBerry in Belgium

Waterloo, Ontario and Brussels, Belgium - BASE, Belgium’s third mobile operator, and Research In Motion (RIM) (Nasdaq: RIMM; TSX: RIM) announced today that the BlackBerry Enterprise Solution™ is available to BASE’s corporate customers in Belgium. 

BlackBerry® is a wireless communications solution designed to help customers enhance their productivity and efficiency by being able to manage e-mail, information and communications whenever and wherever they want. BlackBerry operates in Belgium on BASE's GSM/GPRS network.* 

BASE is introducing the BlackBerry Enterprise Solution for corporate use and, in early 2005, BlackBerry Internet Service™ for smaller firms and individual users: 

• The BlackBerry Enterprise Solution is ideal for companies looking to offer their staff a secure, efficient solution for the mobile management of email, calendar and other corporate information. The enterprise solution requires a corporate IT infrastructure and the installation of BlackBerry Enterprise Server™ software. A Small Business Edition of BlackBerry Enterprise Server is also available for five to fifteen users. 
• For individuals and smaller businesses, BlackBerry Internet Service allows users to access up to ten corporate and/or personal email accounts (including many popular ISP email accounts) from a single device. 

BlackBerry from BASE - the BlackBerry Enterprise Solution

BlackBerry from BASE provides corporate users with secure, push-based access to email, calendar and other corporate applications on an advanced wireless handheld that also features an integrated phone, text messaging, browser and personal information management capability.

Emails delivered to the user's email account are copied, compressed and encrypted and automatically forwarded to the user's BlackBerry handheld. The user can read, reply, file, forward and delete messages from the handheld and all email functions are synchronized wirelessly with the user's email account. File attachments in Word, Excel, PowerPoint or PDF format can be viewed and forwarded.

BlackBerry Enterprise Server software tightly integrates with Microsoft® Exchange and IBM Lotus® Domino™ (Novell GroupWise™ support is expected to be available later this year).

The BlackBerry Enterprise Server Small Business Edition supports five to fifteen users. The introduction of the Small Business Edition by BASE is in line with BASE’s targeted approach towards SoHo or small SMEs (ref. BASE-pro).

 BlackBerry Wireless Handhelds™

BASE offers a choice of three BlackBerry handhelds, the BlackBerry 7230™, the BlackBerry 7730™, and, in December 2004, the BlackBerry 7290™.  Each handheld combines the capabilities of phone and wireless data communications in one compact device.  The features of the BlackBerry handhelds include a high resolution color screen, an integrated ‘qwerty’ or ‘azerty’ keyboard and a trackwheel on the side of the device for easy navigation and use.  The BlackBerry 7230 and BlackBerry 7730 handhelds are tri-band (900/1800/1900 MHz), and the BlackBerry 7290 is quad-band (800/900/1800/1900 MHz) so that users can make phone calls practically anywhere in the world.  The screen of the BlackBerry 7730 is larger to allow for enhanced data viewing capabilities while the BlackBerry 7230 and BlackBerry 7290 are more compact handhelds.  The BlackBerry 7290 introduces a number of enhanced features to the BlackBerry 7200 Series, including Bluetooth® support, 32 MB memory and an enhanced backlight.
