LAS VEGAS, NEVADA--(Marketwire - April 2, 2008) - CTIA Wireless -

Sandvine, (TSX:SVC)(AIM:SAND) a leading provider of intelligent broadband network solutions for DSL, cable, FTTx, fixed wireless and mobile operators, today announced a joint demonstration with Nortel at the CTIA Wireless show in Las Vegas. Sandvine and Nortel will demonstrate dynamic application-based QoS (quality of service) for WiMAX networks.

Sandvine and Nortel have combined their product strengths to demonstrate enhanced per-subscriber Internet quality of experience (QoE) for Internet multimedia applications. Nortel provides a WiMAX 16e base station and gateway through which multimedia applications like video streaming and dynamic peer-to-peer applications flow over a live WiMAX network. Once a video flow is initiated, Sandvine identifies the application and subscriber attributes, and applies policy management in the network. This includes Sandvine signaling the Nortel WiMAX gateway which enforces end-to-end QoS policy on the WiMAX network. The combined solution provides dynamic application-based end-to-end QoS.

This visibility into per-subscriber applications and the ability to manage and enforce policy allows operators to enhance quality of experience for subscribers and better manage network resources. Operators can more effectively plan their WiMAX backhaul and radio network capacity requirements to allow organic growth. They can also protect their infrastructure investment, improve their bottom line and increase subscriber satisfaction.

"Sandvine provides the granular visibility and policy control for WiMAX operators to create innovative service plans and deliver consistent high-quality services, while optimizing the use of valuable radio spectrum and backhaul networks," said Tom Donnelly, Sandvine executive vice president, marketing and sales. "We are happy to work with key industry players like Nortel to enhance service delivery and help make WiMAX operators successful."
