First launched as part of the Sierra Wireless HSPA product line in 2007 to address reduced data transfer speed during simultaneous upload and download, the company’s TRU-Flow technology now includes EV-DO products. According to Sierra Wireless, it is the only technology in the world to improve Web page load times during uplink congestion even with virtual private network (VPN) enabled.

TRU-Flow addresses the way real users work over their wireless connections, Sierra Wireless says. When a wireless network user attempts to upload and download over the wireless network at the same time, congestion can reduce data throughput, slowing down performance. TRU-Flow monitors IP traffic and data throughput to optimize the overall upload and download modem performance.

When there is uplink congestion, TRU-Flow is theoretically capable of a nine times increase in download throughput. Field tests show an average 100% increase in the download throughput performance and an average 100% increase in Web page load times even with a VPN enabled and regardless of the mobile operator network.

TRU-Flow will be integrated into the upcoming Sierra Wireless EV-DO products, including the AirCard 402 data card, the Sierra Wireless USB 598, and EV-DO embedded modules. A white paper about the technology is available at www.sierrawireless.com/product/tru-flow.aspx.
