Sierra Wireless introduces 880U and 881U USB HSUPA modems
Sierra Wireless has introduced new additions to the company’s product portfolio for HSUPA networks, including the AirCard 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 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.

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.
