Sandvine Announces Three New Wireless Customer Wins

WATERLOO, ONTARIO, Mar 24 (MARKET WIRE) --
Attention: Technology Editors

Sandvine, (TSX: SVC)(AIM: SAND) a leading provider of intelligent
broadband network solutions for cable, DSL, FTTx, fixed wireless and
mobile operators, today announced three new wireless customer wins, all
of which came through strategic reseller partner relationships.

Two of Sandvine's newest wireless customers, one located in Korea and the
second in Mexico, are among the top 100 largest wireless providers
globally, by number of voice subscribers. The third new Sandvine customer
is a European WiMax operator.

"Sandvine is helping more than a dozen wireless operators, including
several of the world's largest, better understand the traffic and trends
on their mobile data networks," said Tom Donnelly, Sandvine co-founder,
EVP marketing and sales. "As wireless networks continue to evolve beyond
voice and SMS, our customers are asking for meaningful and accurate
network intelligence to address capacity planning and support the
introduction of new personalized services based on the growing demand for
mobile data."

Sandvine's newest wireless customers are making initial deployments of
Sandvine's PTS platform along with products for congestion management and
network intelligence. Sandvine offers its customers a sophisticated
end-to-end policy management solution that allows service providers to
accurately understand and optimize network performance and provide
policy-based management to address congestion, add new services, mitigate
malicious traffic and enhance customer service.

"Network intelligence is a key business driver for Sandvine and our
customers," said Mr. Donnelly. "We are in the business of making the
Internet better for everyone. By giving wireless service providers tools
to better understand subscribers' bandwidth and application needs,
subscribers get the quality of service and new personalized services that
suit their individual needs and service providers can increase loyalty
and reduce churn on their network."

Since its last customer announcement, Sandvine has also won a new DSL
service provider in Saudi Arabia.
