Market for Two-way Broadband via Satellite Expected to Average 8% Annual Growth

Carlsbad, CA - ViaSat Inc. has shipped its 100,000th DOCSIS�-based two-way broadband satellite terminal. The system is a new approach to broadband satellite communications that lowers the cost of consumer terminals, provides mature back office and customer service systems, and helps make satellite a very cost-effective medium for broadband delivery. The open standard network adapts the Data-Over-Cable Service Interface Specifications (DOCSIS) cable modem networking standard to satellite transmission. The terminal shipment milestone includes both Ku- and Ka-band versions of the SurfBeam� DOCSIS system and reflects ViaSat's role as the supplier of broadband modems to the leading next generation broadband services, including WildBlue Communications, Telesat of Canada, Intelsat Ltd, and SES AMERICOM.

In addition, ViaSat subsidiary US Monolithics, which supplies the outdoor transmit/receive electronics (ODU) for the terminal, has delivered its 100,000 Ka-band transceiver. Significant product cost reductions in the ODU are a vital element in making satellite customer premises equipment affordable for mass markets. US Monolithics has achieved unprecedented price points and volume manufacturing for its high-powered 30 GHz products through a custom MMIC (Monolithic Microwave Integrated Circuit) chip set and innovative design and manufacturing techniques.

The enabling technology for the DOCSIS-for-satellite system is a ViaSat-developed satellite air interface for the broadband networking standard used by millions of terrestrial cable customers. As a result, the satellite system can use low-cost, proven hardware and software elements providing an affordable alternative for two-way, high speed satellite broadband services at typical consumer broadband price points. The implementation also includes technology that mitigates rain fade, a reduction in signal strength caused by heavy rain that at one time was a potential barrier to successful deployment of Ka-band satellite systems. The ViaSat system automatically responds to rain fade with uplink power control and adaptive data coding techniques that help overcome potential outages, eliminating the need for service providers to take on the costs of additional satellite bandwidth that would serve as a �margin� against network-wide rain fade.

For its ground-breaking work in applying the DOCSIS� standard to satellite communications, ViaSat was awarded an Industry Innovator Award by the Society of Satellite Professionals International at the recent Satellite 2006 conference and exposition. The Industry Innovator Awards program recognizes outstanding new contributions to the field of satellite communications by both private-sector and public-sector organizations across a broad spectrum of advanced satellite technology and business applications.

"We have reached a major milestone with the shipment of our 100,000th DOCSIS-for-satellite modem, and we'll continue to build on our broadband successes by creating products and services that meet the needs of the market, " said Mark Dankberg, chairman and CEO of ViaSat. "Working with our service provider partners, we are developing advanced technology to help meet the growing demand for affordable, high speed broadband services."

"WildBlue has been very pleased with ViaSat's Ka-band equipment. The low cost and high performance has been integral to WildBlue's extraordinary growth since we launched our satellite broadband service for consumers and small businesses and the resulting 94+% customer satisfaction rate among our tens of thousands of customers," said Erwin Hudson, WildBlue executive vice president and chief technology officer.

"Northern Sky Research (NSR) anticipates that satellite broadband services will exhibit some of the greatest growth potential in the commercial satellite industry," said Chris Baugh, President, NSR. "Based on extensive analysis in NSR's Broadband Satellite Markets, 5th Edition report, NSR expects broadband satellite subscribers to increase from 1 million in 2005 to over 2.2 million in 2010, and demand for ViaSat's SurfBeam modem further underscores the significant market opportunity."
