Sierra Wireless adds new USB modems to HSUPA product line



    AirCard(R) 880U and 881U USB modems offer the latest in mobile broadband
    connectivity on networks around the world

    VANCOUVER, Aug. 29 /CNW/ - Sierra Wireless (NASDAQ:   SWIR - TSX: SW) today
introduced new additions to the company's product portfolio for HSUPA
networks - the AirCard(R) 880U and AirCard 881U USB modems. Commercial
shipments are expected to begin in September.
    The new AirCard HSUPA USB modems offer tri-band connectivity to mobile
broadband networks worldwide and increased data speeds in a ubiquitous,
simple-to-use USB interface that makes them a practical choice for customers
sharing a single wireless account between computers or using their wireless
service with a desktop. To further enhance their flexibility, the AirCard 880U
and 881U also offer support for both Microsoft Windows (Vista, XP, and 2000)
and Mac OS X users.
    "Sierra Wireless USB modems offer versatility for customers without
compromising the quality and performance they need from their mobile broadband
connection," said Trent Punnett, senior vice president, Marketing and
Corporate Development for Sierra Wireless. "With the addition of significantly
faster HSUPA technology, that connection gets even better, delivering a mobile
experience that is remarkably similar to what many of our customers expect
from their wired Internet service."
    With Sierra Wireless AirCard 880U and 881U USB modems operating on an
HSUPA network, mobile data customers will be able to send email attachments,
upload information, and transmit data from portable devices at speeds more
than five times faster than on current HSDPA networks, up to a theoretical
maximum speed of 2 megabits per second (Mbps). This improvement in uplink
speed creates opportunities for a variety of new applications involving
client-generated content, such as web conferencing and live video, and for
customers working over a virtual private network, the user experience is
expected to significantly improve. Downlink speeds are also improved, with a
theoretical maximum download speed of 7.2 Mbps.
    For use in areas where HSUPA networks are not yet available, the AirCard
880U and 881U USB modems are fully compatible with HSDPA, UMTS, EDGE, GPRS,
and GSM network technologies on all frequencies currently used worldwide. The
AirCard 880U is optimized for Europe and Asia, while the AirCard 881U is
optimized for North America. To ensure there is always enough power support to
handle peak or fringe area transmission requirements without compromising
performance, the AirCard 880U and 881U USB modems also include an internal
battery that supplements the power from the USB port when extra power is
required.
