The SurfBeam system is designed from the beginning (due to its DOCSIS® heritage) to deliver highly scalable, high performance consumer/small-office and small-medium enterprise (SME) broadband services over satellite, and it delivers the economics that make broadband-by-satellite a great business as well.

The ViaSat SurfBeam® Broadband System is a totally new kind of satellite-based system designed expressly for building broadband access networks, not like modified Very Small Aperture Terminal (VSAT) systems that have failed to successfully expand to larger networks. With over 500,000 terminals shipped, it has become the single most popular web-centric broadband satellite networking system ever.

The SurfBeam system is the network technology behind these fast growing broadband services, and it can bring the same success to you: WildBlue Communications, United States ; Eutelsat Tooway™ Ku- and Ka-band consumer broadband in Europe; Telesat Ka-band consumer services in Canada; Intelsat/Orbit Communications Ku-band service, Middle East; Pegaso Banda Ancha, Mexico; Smart Digital Networks, Malaysia.

With SurfBeam, ViaSat has successfully integrated the widely used Data-Over-Cable Service Interface Specification (DOCSIS) broadband cable industry technology with the latest in advanced and proven satellite technology.

Key SurfBeam Broadband by Satellite Advantages
Highly scalable architecture allowing you to economically start with a small network that serves only a few thousand customers, then easily grow the hub infrastructure to accommodate hundreds of thousands, or even millions, of subscribers. High system capacity and lower bandwidth costs using advanced ViaSat technologies that give customers a better user experience, support more applications, and provide you with higher system capacity to serve more customers. Consumer priced terminals because of the economies of scale inherent in millions of DOCSIS chipsets already produced and proven in the field, along with ViaSat success in shipping more than 500,000 units to date.

Integrated front and back-office support. Unlike other satellite-based systems, the SurfBeam system also includes the front and back-office support functions that simplify managing your customers and network:

The SurfBeam system is cost-effective on traditional Ku-band broadbeam satellites and brings unsurpassed network capacity, low cost-per-bit, and ability to scale to millions of subscribers using new Ka-band spotbeam satellites.

Summary

APT (APT Satellite Holdings Limited) successfully launched its first satellite, APSTAR-1, in 1994. Since then, APT has experienced extensive growth, and operates five on-orbit satellites, providing coverage over Asia, Oceania, and parts of the Pacific Ocean that extends as far out as Hawaii. The APT satellite fleet comprises of APSTAR-1, APSTAR-1A, APSTAR-IIR, APSTAR-V and APSTAR-VI. All of the APSTAR satellites are built upon the latest and most reliable satellite platforms, and carry high performance payload to meet market demands, providing high quality transponder services for the broadcasting and telecommunications client within Asia Pacific region. APT currently provides C-band and Ku-band transponder services to satisfy the needs and demands of various customers.

APSTAR-V and APSTAR-VI epitomizes the new generation of high-power and high-reliability communication satellites. Given their outstanding performance, they are able to provide excellent quality of service to our broadcasting and telecommunications customers. Both APSTAR-V and APSTAR-VI C-band and Ku-band transponders provide broad coverage and optimal power to support such uses as TV program broadcasting, live satellite TV feeds, news gathering, corporate VSAT networks, distance learning, data broadcasting, internet backbone, broadband Internet access, cellular backhaul, etc. APSTAR-V and APSTAR-VI are separated in their orbital positions by 4 degrees longitude. Their close proximity allows for a good backup configuration in case of contingency. These satellites also possess high priority of orbital slot filing, as well as being able to aggregate broadcasting neighborhood effect over Greater China Area. These advantages guarantee the service integrity and reliability of our customer service transmissions and their cost-worthiness.
