| DSL has been
hailed as a great solution for residential broadband needs.
You may have heard this term from friends and neighbors when
talking about their fast internet connection. It's true, DSL
is much faster then a dial-up internet connection, but is
it all it's cracked up to be? With
speeds of up to 140 times faster than dial up internet access
its definitely fast but the problem is you don't always
get the advertised speed. You DSL connection is highly dependant
on your distance from the phone company. If you're over
5,000 feet your signal will begin to drop off and your connection
will be degraded, i.e. slower speed. At about 15,000 feet
from the phone company (3 miles) your signal will completely
cut off.
The second problem with DSL is the fact
that it's highly over subscribed. Oversubscription means
that many people are pulling from the same resource. During
the afternoon when people are at work there may be plenty
of bandwidth to have, but in the evening when everyone is
looking up the news, going through e-mail, or shopping online,
access tends to be strained. Many people pulling from the
same limited resource will find that there's only so much
to go around. What does this mean to you? Slow speeds! It's
interesting to note that DSL companies lampooned cable internet
access as being shared by the neighborhood. Commercials
displayed neighbors at each others throats for overusing
the connection because it affected other's use. The irony
of the commercials is that DSL users suffer from the same
problem of common access. It's a great solution, but don't
let them fool you….It's not perfect! |
