Telephone, Internet and TV services on a regular basis and maintain the current provider. Easy to be a single supplier and one bill a month. Despite the availability of VoIP (Voice over Internet Protocol), the line between the different services and more blurred.

Broadband Internet service (High Speed) for residential or small business needs are already available from two sources: DSL, telephone system piggybacked on the cable from the phone company or cable, because the system that piggybacked on the cable TV cable. In the year 2008, approximately 25 million subscribers are used for cable broadband, and about 22 million subscribers will be used for DSL. In 2001, a total of 5 million customers used in both the cable or DSL broadband.

For many TV Coaxial cable has a better performance than that offered DSL, but if you are very price conscious, cable and DSL can compete. So, in a discussion of broadband choices, we have with cable and DSL, but we also discuss the new options are now available as a WildBlue satellite, and services that will come available as WiMAX (and WiFi throughout the city fire-spot) and ViaSat (satellite communications on steroids).

Impact of Hollywood (especially HDTV):

Although a relatively small number of users, research indicates that systems such as BitTorrent and YouTube account for more than half of Internet traffic. In 1995 the amount of data transacted over the Internet backbone was about 1.5 million GB. In the year 2006, it has grown more than 700 million GB.

Abi research projects that the number of video downloads increased from 215 million downloads this year (2008) and 2.4 billion downloads in 2012. This number becomes more impressive when one take into account a large percentage of people downloading at the year 2012 will be HDTV files, a large (non HDTV movie about 3 GB / Hour HDTV depending on the file encoding: an MPEG-4 encoded movie files are about HDTV 5 GB / Hour, an unencoded 1280 X 720 movie files of more than 150 GB / hour, and unencoded 1920 X 1080 This movie files more than 350 GB / hour).

In 2010, estimates call for 80-90% of Internet traffic transfer videos.

Cable and telephone companies (DSL):

Broadband cable capacity is approximately 30 Mbps bandwidth, however, speed may vary. Unfortunately, the size of real-world situations may be more difficult. Like many people in your neighborhood using the same broadband service as you, and those many people use the bandwidth, for video downloads for example, then you'll share some resources, and your performance will suffer. Most service providers to provide services to 3-6 Mbps bandwidth for downloading. Upload Bandwidth less: usually between 200-600 kbps.

DSL speeds average in the U.S. is 768 kbps. One type of DSL technology, VDSL, is the capacity of 30 Mbps bandwidth, but the service is not too available. In contrast, phone companies more common ADSL or SDSL services (cheap and slow).

All Cable Broadband and DSL providers usually employ bandwidth caps for residential and small business customers. Service providers concerned about the total capacity of the network capacity they might sanction institutions that can provide equal performance to all their clients.

Cable companies and mobile HDTV:

Verizon to build fiber-optic network that will be able to handle 200 + HDTV channels broadcasting in addition to all regular TV channels.

Many cable operators available bandwidth is only available on 10-12 HDTV channels without a major retooling their networks.

WiMax and LTE:

Large areas in the capital, the U.S., WiMAX will be available in late 2008. Sprint will make WiMAX the first business in Baltimore in September. WiMax supports peak data on broadband speeds of 20 Mbps, but as with most broadband technology, the bandwidth will be shared between users. On average, users will see data rates between 1 Mbps and 4 Mbps.

Most wireless operators jump WiMax, planning instead to build a network using similar technology called Long Term Evolution (Malte), is the successor to current cellular respiration technology. WiMax has a head start Malte, who won t be ready until 2010. Both these technologies called 4G network (current state of art technology for the mobile Internet to be called 3G). As broadband telephone services that are important to you, this product will be very interesting. Unlike other GSM and CDMA, all the 4G network based on Orthogonal Frequency Division Multiplexing (OFDM), sometimes also referred to as Discrete Multi-tone modulation. Malte of two equal and WiMAX-based technology, a unified standard possible in theory, and the ongoing discussion. Motorola has said 85% of the technology and equipment to work in the WiMAX infrastructure will be used again for Malte equipment.

Malte WiMAX and can provide a large amount of work at the grass roots power required bandwidth for mobile devices. Another benefit of WiMAX / Malte is the ability to communicate beyond line-of-sight (different conventional WiFi), and send to large buildings in theory making dropped calls, such as cell phones today, old man. A company called MobiTV will use the WiMAX network to broadcast TV, including HDTV. VoIP (telephone service) has been used in WiMAX networks in other parts of the world.

Satellite Broadband:

Also introduced into the Broadband market, is the WildBlue satellite. Broadband services do not need cable or phone line. WildBlue satellite broadband service offers download / upload speed broadband starting at only $50 per month (512 kbps download speed and upload speed up to 128 kbps), or $80 per month (1.5 Mbps and download speeds up to 256 kbps upload). For those who live in areas not well served by Cable Broadband and DSL, this is an attractive alternative. iNetVu provide a portable system for the vehicle.

A powerful new satellite, Viasat 1, itazindua 2011. This satellite will improve the satellite's highly competitive in this area. ViaSat-1 has a total throughput capacity of more than 100 Gb / s, which is more powerful than the current U.S. fleet of two directions C, Ka and Ku band satellites are combined. In 2010, the service will launed in Europe and Ka-Sat.

All WildBlue and 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. DOCSIS able to handle rain fade, to reduce the signal caused by heavy clouds, as a storm. DOCSIS is automatically ready for the signal reduction caused by the weather variable power control and data coding techniques.

ViaSat-1 will further increase the capacity by 10x frequency reuse by using a technique called SpotBeams (WildBlue also uses SpotBeams). 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. Spotbeams can be compared to highlight. General area SpotBeams signals 100-200 miles. The same frequencies can be reused many times, but with different perspectives and regions.

WildBlue and ViaSat is a geosynchronous satellite. A geosynchronous satellite remains above the same spot on the earth orbiting around 36.000 kilometers above the equator. Signal should be back and forth, and if time travel has fallen by about 1 / 4 seconds.

Satellite HDTV:

While HDTV local channels available on cable than satellite, DirecTV and Dish Network each offer more national HDTV channels. DirecTV offers about 60 national HDTV channels and Dish Network has about 50 HDTV channels. DirecTV and EchoStar plan additional satellites to provide at least 150 national HD channels and local stations in HDTV.

The satellite will be made not much, how many channels they can carry over to how much they can get, Bob Scherman, Satellite Business News.

In 2010, estimated that 60% of TV receivers will use the satellite signals, from 15% in 2002.

Summary:

DSL speeds average in the U.S. is 768 kbps.
The average speed of more than Cable Internet broadband is around 4.5 Mbps.
WildBlue service around 500 kbps.
WiMAX services will be between 1 Mbps and 4 Mbps.
Services ViaSat-1 (2011) will be about 2 Mbps.

HDTV service is now more fully served by the satellite TV companies like Dish Network DirecTV. The new system was implemented by Verizon, or perhaps a thorough reform and local cable TV operators to provide better competition.

Provision of Broadband and HDTV services in the United States is now divided from satellite manufacturing. All may be available from local retailers, but the system is not unified. This compares less timed and Europe and Eutelsat, which itazindua Ka-Sat in 2010 (Ka-similar Saturday ViaSat-1, has been discussed above), and install this satellite satellite in the environment, so a system will receive all TV signals from satellites Hotbird their system, and receive broadband high performance of the Ka-Sat. This is unfortunate for American consumers.

Currently, more than 90% of broadband subscribers using either a cable or DSL broadband. However, eligible to enter the new competition is the Fray, and will be difficult for the service to maintain their market share.
