KA-SAT make VoIP calls over Internet in good quality and at low cost

Currently called KA-SAT and scheduled for launch in third quarter 2010, the satellite will be configured with more than 80 spotbeams. A network of eight gateways managed by Eutelsat, and which will provide access to KA-SAT, will form an integral part of the new infrastructure.

"By combining a satellite equipped with more than 80 spotbeams and a network of ground stations, this new programme will deliver more capacity than any other satellite programme deployed worldwide," Michel de Rosen, Eutelsat chief executive, said. "These new resources will in particular benefit internet service providers, enabling them to extend broadband to consumers and enterprises in areas unserved by terrestrial networks."

Eutelsat will locate KA-SAT at 13° E where it will join three large HOT BIRD Ku-band broadcasting satellites. This collocation will enrich the range of consumer entertainment services offered from the Group's prime neighbourhood by enabling satellite homes to receive television in the Ku-band and new rich media services in the Ka-band through a single dual-frequency antenna. In advance and in preparation of KA-SAT, Eutelsat is using Ka-band capacity on its HOT BIRD 6 satellite for a new consumer broadband service, launched in Europe at the end of 2007, and called Tooway.

The service is operated by the Group's broadband subsidiary Skylogic, in cooperation with ViaSat. Tooway uses ViaSat's well established SurfBeam system. KA-SAT is the European equivalent to ViaSat-1, a high-capacity Ka-band broadband satellite ordered by ViaSat to serve the North American market and planned to launch in 2011.

ViaSat and Eutelsat are cooperating closely around ViaSat's Ka-band SurfBeam networking system and a similar wholesale business model that works through ISPs, telecommunications companies and pay-TV platforms to serve subscribers. KA-SAT marks a material step forward in multi-spot satellites.

In particular, 1stgen multi-spot satellites using ViaSat SurfBeam technology and operated by WildBlue and Telesat have already reached more than 300,000 Internet subscribers since their launch in 2005. As a standard used by several tens of millions of cable customers worldwide, DOCSIS, together with powerful new Ka-band multi-spot satellites can facilitate important economies of scale to enable satellite-based consumer Internet services to achieve costs and bandwidth comparable to ADSL.
KA-SAT, coupled with ViaSat's next generation SurfBeam, will deliver a total throughput of over 70 Gigabits per second. Based on the EUROSTAR Eurostar-3000 platform, KA-SAT is the 17th satellite commissioned by Eutelsat from EADS Astrium. Designed to operate for 15 years, it will have a launch mass of 6.15 tons and a payload consuming more than 11 kW of power, with solar arrays generating 15 kW of power.
The Ka-band satellite — known as KA-SAT — launched on 26 December. It has a capacity of up to 70Gbps. KA-SAT has been designed by Eutelsat to provide broadband coverage for Europe, northern Africa and some parts of the Far East and is expected to be fully operational for residential broadband subscribers from late in the second quarter of 2011.
Eutelsat Communications has selected EADS Astrium in January 2008 to deliver its first satellite operating exclusively in Ka-band frequencies. The satellite will form the cornerstone of a major new satellite infrastructure program that will expand capacity for consumer broadband services across Europe and the Mediterranean Basin, while providing new opportunities for local and regional television markets.
NEWSA satellite that will be used to provide residential broadband connections for Europe, northern Africa and some parts of the Far East has been successfully launched, French satellite company Eutelsat announced on Monday.
Eutelsat will not offer the service directly to consumers, instead selling the service wholesale to providers that will then resell the connections. Pricing for the service is currently unavailable.
The satellite will provide download speeds of up to 10Mbps and upload speeds of up to 4Mbps for Eutelsat's Tooway consumer broadband service, a company spokesperson told ZDNet UK on Wednesday. There is potential for higher speeds in the future, the spokesperson said. Until KA-SAT, Tooway provided a maximum download speed of 4Mbps.
On 26 November Avanti communications successfully launched its own broadband satellite — Hylas 1 — capable of delivering up to 10Mbps download and 2Mbps upload broadband to around 350,000 homes.
Hylas 1 is due to begin serving customers in Europe — with the exception of Scandinavia — with satellite broadband connections for from £25 per month in the first quarter of 2011.

    I drop a comment each time I especially enjoy a post on a website or
    if I have something to contribute to the discussion.
    It's triggered by the passion communicated in the article I read. And after this post "KA-SAT make VoIP calls over Internet in good quality and at low cost". I was actually excited enough to drop a comment :-) I do have 2 questions for you if you usually do not mind. Could it be only me or do some of the responses appear like they are written by brain dead people? :-P And, if you are writing at other sites, I'd like to keep up with you.

    Could you list the complete urls of all your shared sites like
    your twitter feed, Facebook page or linkedin profile?
