Satellite TV VS Cable.
The truth about cable, just out dated technology!

What is cable? Cable is out dated technology in the way a cable company is using it! Just like every thing else in the world, cable has limitations. A Cable system is a series of wires run throughout an area. The wires are connected to a small fiber trunk at limited locations, called nodes. Cable is strung throughout the city, like an extension cord hooking up all of the appliances in a home.
Think of a cable wire and compare it to a garden horse VS a water pipeline. Would you put out a massive fire with a garden horse, or would you use a fire horse? Now think about this, would you try to supply all the water needs of a large city with a garden horse, a fire horse, or would you choose a large water pipe that is designed to handle a city?
The analogy of a water pipe is perfect to understand the benefits and limitations of a cable wire. A small size pipe is ineffective against greater demand than the pipe was made for.
A coaxial cable can only be extended so far and only handle a certain amount of data before quality is affected. The data can be in the form of television channels, Internet, and phone service. The important thing to know is that a cable wire is out dated technology for the way the cable company is using it. In the phone industry, they call the cable wire a ds3 or a t3. Companies, depending on their demand for data, would order a t1, a t2, or a t3. Each of the wire classification contain a certain number of data channels on it. A t1 is equal to 24 phone lines or 1.4 Megs of uncompressed data. A t3 is designed to carry 672 data channels but not an infinite number.
It is important to realize that when a business uses a t1, t2, or a t3, it is installed as a private line. The only person connected to the t3 is the business that ordered it. The reason is because when a t1, or even a t3 is shared, it cuts down on the quality of the signal by hindering bandwidth. For example, a phone company may carry the phone calls from a group of homes over a T1, t2,or a t3 line and route traffic back to the central office. However, they will only use one channel per call. This explains why when a person goes to make a call he sometimes gets a message that says all circuits are busy. When a company orders a “T” line, the t1, t2, or t3 line is completely private all the way back to the central office. However, the cable industry will string, and amplify, a cable
wire to more than 800 households off a node. A cable company sends TV channels, phone service, and data over the limited cable line. It takes 24 channels to get 1.5 Megs of high speed internet for a one business. Hence, a cable company is over utilizing the cable wire.
Years ago, cable began as a large antenna on a hill connecting nearby people to it, for a small fee. People would pay to get better reception of local channels. The cable wire worked great for the limited demands on it.
As the cable industry grew and more and more channels were launched, cable began to reach its limitations on everything but the price. Subscribers started seeing lines and picture distortions on channel two, three, four, and so on. People started to have greater outages. The rise of satellites and small home dish receivers bought competition to the cable industry. After all, the cable companies got their signal from satellites, why shouldn’t the subscriber? For awhile, it looked like the cable industry was going to go out of business.
The introduction of different technology has extended of the life of the cable industry for a short while. Cable companies started combining fiber trunks with digital data compression in order to keep expanding their offerings, and raising their prices.
Many subscribes were even told they were on a complete fiber system and had fiber to their home but this is false. The cable company only installed a fiber truck and put up new coaxial in neighborhoods to replace the worn wires of the past. If a person thinks about a tree and all its branches reaching out, or an extension cord with all the appliances hooked to it, he can understand how cable is strung from a single fiber line to cover the whole city and how weak the signal can get. The closer a person is to the fiber trunk, the better the picture will be, but if he moves further away his picture quality will decline. However, thanks to the fiber trunk and digital compression, most subscribers are receiving a better picture than they were use to and receiving more channels but the claims of cable industry that this digital compression picture is the same digital, high quality picture offered by the satellites companies is completely false. Most of the new rebuilt cable systems were only about 750 megahertz or less in bandwidth. However, the standard small satellite system is around 2500 megahertz in bandwidth. The difference in bandwidth is the reason a satellite dish can offer a much higher quality picture and more channels.
Comparing digital compression technology to the 100 percent digital picture of a satellite is like comparing a garden horse to the main water pipeline of a city. A satellite company has a lot more room in their bandwidth to offer unrestricted and uncompress channels, and this is also why the average cable company offers about 20 high definition channels while dish companies offer more than 70. Consumers must know the difference: it’s the size of the pipe that counts and not how large the cable company can make the bill.
Satellite and dish technology is relied on by every major institution in America, such as Home Land Security, the military, and even the local cable company.
Remember this, there is fiber and coaxial run throughout the united states, but local cable companies use satellite and dish receivers to bring them the highest picture quality. They then compress and resend the signal, at a much larger price but less quality, to their customer. The reason cable companies use a satellite instead of a wired line is because they know a dish delivers the highest picture quality.
The cable industry is in great trouble because of the limitations of the cable wire, and the desires the cable industry to max out the bandwidth in an attempt to equal the bandwidth and technology of satellite companies. The wire is also subject to decay of the elements. Therefore, as time goes on, the cable quality will continue to decline as cost increases.
For now, cable companies are happy to repackage the outstanding quality of a satellite dish and compress the signal to their customers at a much larger price, while claiming at the same time that a satellite signal is bad. Soon customers will realize that their bills keep rising because they are paying for and maintaining outdated technology, and getting sub par quality and service in return. If a dish is good enough for the cable company, then it should be good enough for the consumer. Cut out the middle man, and switch to the dish..
