Bytemobile “Powers Up” with Acquisition of ProQuent; Announces T-Mobile Content-Filtering Win

 London UK and Mountain View, CA – March 14, 2005 – Bytemobile, Inc., the global leader in mobile data optimisation, announced today that it has acquired ProQuent Systems Corporation in a stock-for-stock exchange. ProQuent, a developer of mobile multiple services switching platforms, provides scalable, low-latency, 7 layer content inspection solutions that are important components for providing visibility and enforcement of mobile network policies on IP traffic in operator networks.

The acquisition expands Bytemobile’s offerings to include a broad range of intelligent content optimisation, filtering, tracking, analyzing, authorising and enforcing solutions that help operators better leverage and monetise their mobile networks.

Bytemobile also revealed that T-Mobile UK recently deployed its content filtering technology to enable their new “Content Lock” service offering, which provides a mechanism for parental control of inappropriate material. While UK operators have led the market with services geared to parental control, this issue is becoming increasingly important to mobile operators around the world.

“Bytemobile’s mission is to maximise the performance and value of mobile data networks,” said Hatim Tyabji, Bytemobile’s chief executive officer and board chairman. “The ProQuent acquisition extends our ability to do that, with content management and billing solutions that meet the critical challenges operators face today.”

“Bytemobile’s optimisation solutions are already increasing data subscription and improving network profitability for more than 50 operators,” said Rod Randall, ProQuent board chairman and senior managing director for venture capital firm Vesbridge Partners.

“We saw a terrific fit and complementary market timing between our two companies, which was reinforced with some of the deals we won prior to joining together. Content awareness is the next dimension of network intelligence that will be critical to preserving and adding profitability to the network operator business model. The combination of content optimisation, content filtering, and content-based billing is tremendous and provides an unmatched platform for valuable new content-based network services.”

“To capitalise on mobile data market opportunities, operators must improve both network performance and the user experience,” said Philip Marshall, director of wireless technologies, The Yankee Group. “The first stage is to optimise the traffic over the core network; then operators need new content-aware networking solutions that help them intelligently make money from that traffic with appropriate billing options and value-added services.”
