Internet bandwidth communications needs continue to grow around 50% every year. Satellite Broadband Internet needs have been growing very fast, that WildBlue has stopped taking orders in the United States.

Demand tends to grow rapidly in the near future. HDTV signals require 4-5 Bandwidth of infection is very similar to standard definition video, even with advanced MPEG-4 encoding. In 2010, estimates call for 80-90% of all internet traffic transfer videos.

Now there are more than 600,000 Internet customers in the North American satellite, usually in more rural areas where broadband Internet if not available. Both times have launched a new internet satellite, satellite Internet customers increase has been followed, but in a few months, it sold out capacity in the main geographical areas, customer growth restriction.

Current satellite system designed to t in the high bandwidth demand that people need, such as HDTV, graphics, VoIP, and peer-to-peer network.

  • It doesn't like that. Day to day consumer internet interactions involving high-bandwidth activities like video and Multimedia are not part of the satellite service planning in advance when they are designed. We aim to give consumers the experience is much better based on a lot of sophisticated technology market. This new power is not only very appropriate technology, they also returned affordable, said Mark Dankberg, ViaSat CEO.
    • ViaSat has a plan to address the needs. ViaSat-1 carried by the launch in 2011. The amount of bandwidth enabled by ViaSat-1, equipped with ViaSat's SurfBeam networking system, is unparalleled. Total throughput is designed to be more than 100 gigabits per second, which is more powerful than the current North American fleet of two-way Ka, C and Ku band combined. ViaSat-1 will be much increase in quality, capacity and availability of high-speed satellite Internet services for U.S. and Canadian consumers.

    In 2010, Ka-Sat satellite launch similar services in Europe.

    New satellites will also be used to provide internet services, TV (including HDTV), internet telephony, satellite communications and defense. In 2010, 60% of TV receivers will use the satellite signals, from 15% in 2002. ViaSat terminals use a networking technology that uses satellite bandwidth efficiently, is called DOCSIS (Data Over Cable Service Interface specification), reducing the cost of Internet services to users. Terminal with satellite modems and Ka band transceiver. Throughout the height of the ViaSat-1 makes it ideal for transmitting new video applications require a bit Ultra-high-level such as HDTV, HD digital cinema and 3D television.

    DOCSIS also includes technology that addresses rain fade, reducing the signal strength caused by heavy rains. System automatically in response to rain ViaSat fading uplink power control and adaptive data coding method.

    ViaSat-1 and Ka-Sat will provide 10-15 times a Ku band satellite capacity through frequency reuse by using technology called spotbeams. Spotbeams as a highlight. Rather than send a signal of the continent, most of the region in spotbeams signal 50-100 mile radius. Because the frequency of the target area is small, the frequency spectrum can be reused in a different location.

    DSL speeds average in the U.S. is 768 kbps. The average speed over the internet cable is approximately 4.5 Mbps. ViaSat-1 will be the cost of basic services at 2 Mbps, increasing satellite and DSL in the 80th percentile. Premium DSL plans will easily win the best services, and satellite set better now for the average cable.

    The position will Eutelsat Ka-Sat satellite in the same neighborhood as the three available Hotbird Ku-band satellite at 13 degrees East. Position Ka-Sat satellite and these ads they can bundle broadband and broadcast services. Customers in Europe will be able to receive television in the Ku-band and to announce broadband services in the Ka-band through a dual frequency antenna.

    ViaSat-1 involves effort between ViaSat, chloral, TeleSat, and Eutelsat. Eutelsat Communications is the holding company of Eutelsat SA satellite currently serving 24 European continent, such as the Middle East, Africa, India, and most of Asia and the Americas, Eutelsat is one of the world's three leading satellite operators in terms of revenue.'S Eutelsat satellite broadcast on television in 2700, when more than 1000 channels of satellite broadcasting bird HOT waiter at 120 million cable and satellite homes in Europe, the Middle East and North Africa.

    Chloral was selected to build ViaSat-1 high-capacity broadband satellite. Chloral is a vaccine to invest in Canada part of the satellite in anticipation of Telesat Canada (which is 64 percent owned by chloral) Canada uses the power of service. Telesat's satellites are planned for 115 West longitude orbital slot and Telesat also provides telemetry, monitoring & control (TT & C) for the satellite operation.
