Broadband:-
There are several types of broadband Internet access, and
each has it's own set of pros and cons. Following is a
description of each type of broadband Internet access:
Cable
Cable Internet is the most widespread form of
broadband in service today. Cable Internet is, not
surprisingly, delivered over the same physical cable and
company that delivers cable TV. One of the reasons that
cable is the most common form of broadband is that the
infrastructure to provide the Internet access was to a large
degree in place prior to the explosion in demand for
broadband. Implementation is usually fairly straightforward,
as it usually just requires the installation of a cable
modem and some wiring to the computer. The limitation of
cable is that it is typically a shared connection in the
sense that all of the Internet traffic in a given area has
to pass through a common network node. This means that the
more people in your neighborhood that have and use cable
Internet, the slower the connection will be. However, in
areas with few cable Internet users, speeds can be extremely
high, even in the 1-5M range.
Satellite
Satellite
is a growing type of broadband access, although still
primarily limited to those areas and those users who cannot
get any other form of broadband. Satellite broadband began
by using the satellite to broadcast the download, and to
have a dialup connection provide the upload link. With
improved technology, satellite broadband now offers upload
via satellite dishes. Because it is a newer form of
broadband and still to some degree in its infancy, satellite
broadband typically is more expensive to install and on a
monthly basis than most other forms of broadband. In
addition, the bandwidth limitations currently provide not
much more throughput than regular 56K dialup, although this
seems to vary greatly from provider to provider.
Wireless
The term '
wireless' has many meanings, but wireless
in relation to broadband Internet access refers specifically
to
connectivity provided by a wireless signal
between a transmitting tower and a transmitter/receiver
installed at a home or office. (The confusion usually comes
from the term 'wireless network, which refers to a wireless
router in the home that connects wirelessly to all of the
computers within the home. It is possible to have wireless
broadband in conjunction with a wireless network in the
home.)
DSL (Digital Subscriber Line)
DSL is one of the most common types of broadband
Internet access in use today and is continually growing as
DSL networks expand their networks. DSL works by
transmitting a digital signal over a traditional phone line,
thereby avoiding the expense of installing a separate
digital line as in ISDN.
The main limitation to DSL is that it is
distance-sensitive. The signaling required for a DSL
connection cannot travel more than a certain number of feet
over the phone wire from the DSL equipment at the local
phone switch. The bandwidth rate that will be available to
you will depend on the distance you are from the DSL
equipment- the closer you are, the higher the bandwidth you
can expect. Currently it is possible to live in a heavily
populated area that does have DSL around, but not be able to
get DSL because your home or business happens to be a block
or so too far away from the local phone switch. The good
news is that DSL providers are still expanding their
networks not only to new markets, but are continually
working on new technology to expand the 'service distance'
to fill in the holes of coverage in the markets where DSL
already exists. In addition, competition continues to drive
the cost of DSL lower and lower.
