This can be to some extent attributed to the fact that the dotcom boom began in California. This is one of the main causes why some people prefer the cable to the DSL service. The ones which match your needs the most will obviously be the best choice for you.

It would be really handy if you could keep your home connected to the Internet 24 hours a day, 7 days a week, it would make it easy to send off a quick e-mail or look something up when you need to. The hotel's website will usually tell you if and where you can connect to the internet. Think of dial-up internet service as trying to run a lot of water through a small pipe. You can self-install, but you'd better know what you're doing. However, this is true more in theory than in practice. Although it may seem cheaper to simply rent a modem for a few dollars a month rather than buy one straight off, think about how long you are going to use this service and if it will be cheaper in the long term for you to buy one instead; also can you change your mind later on?
There are three factors to keep in mind when contemplating DSL availability: Distance, distance, distance. Well, that's one word three times, but it's still the most important factor in whether you get DSL service and what level of quality you can expect.
This distance means that DSL availability has yet to reach every corner of the country, despite popular demand. We'll look at why this is and what secondary factors matter, below.
Copper Wires
Regular DSL, the sort you'd order for home service from a provider like Yahoo, is carried from the provider to your house by the pair of copper wires that are already carrying your phone service.
As a digital signal travels farther and farther from its source, it degrades. Think of it like a radio station you're listening to when suddenly you drive through mountains. The signal dissolves into a bunch of unintelligible static. The same thing happens to a digital signal.
So generally, you have to live within 18,000 feet of the service provider to qualify for DSL availability. No one expects you to get a ruler and measure the distance to the nearest service provider. There are several websites that will let you input your address, then tell you whether or not you qualify.
Even if you're within 18,000 feet and do qualify for DSL availability, the closer you are to the provider's office, the faster your DSL will be. Service at 9,000 feet distance is nearly eight times as fast as service over 18,000 feet.
Load Coils
A secondary factor affecting DSL availability is a tiny device installed by some phone companies called a 'load coil.'
The copper wires carrying your phone service have a broad bandwidth - that is, they can handle a wide range of frequencies. The human voice is clearest from 300 to 3,400 Hz, so that's the portion of wire reserved for telephone calls.
When the telecomms decided to add DSL availability to the same copper wires, they opted to use frequencies in the 4,000 Hz and up range. This shouldn't have been a problem except that some companies had added load coils to the wire lines.
Load coils enhance the lower frequencies. This equals clearer voice transmission, but can interfere with DSL availability. Ask your telephone service provider if this is the case on your lines. You might want to consider going with a cable provider instead.
So don't take it personally if you find out you don't qualify for DSL availability. The problem is with the telecomm, not you!
