The different types of broadband Internet | ||
|
15 April 2002 Youve probably seen the ads for broadband
Internet. The future is here at zillion times faster than the old Internet.
The Internet will never be the same. So what is broadband Internet and is
it worth the hype? Basically broadband is a term for any Internet connection
faster than a dial-up modem account. Apart from the speed, the biggest difference between a
broadband and dial-up access is the billing. Dial-up accounts are generally
calculated on a time basis while broadband are calculated on a download and
speed basis. The main reason for this is that you are always connected
on a broadband account. A dial-up account has to dial the Internet provider
when connecting to the Internet. While the costs of broadband access look high at first,
for many users they can be cheaper than a dial-up account. With a broadband
connection you dont need another phone line and you are not paying a
connection fee each time you connect. The danger with broadband accounts is that you can run
up a huge bill if you exceed the monthly download limit. Optus cable users
dont currently have an excess-usage charge but they will boot off users
who use too much. There are four basic broadband technologies available
to homes and small businesses. ISDN is not worth bothering with. The other
three are satellite, ADSL and cable. Each product has their own benefits and
disadvantages. Cable is the most common broadband option in Australia
at present. It uses the pay-TV cables to access the Internet. Obviously to
get it you must have pay-TV in your street. Unfortunately this rules out over
half the country. If you already have cable-TV then you can probably get
cable Internet installed. If you dont already have the cable installed
then the cable company will have to connect you. This will involve running
a cable into your house. Cable is a fairly stable technology but it is hampered
by the lack of coverage in many areas. There appear to be no plans to extend
cable in the major cities. Optus
Cable ADSL is a newer technology that uses the existing phone
lines. It needs special equipment at the local phone exchange and you cannot
be more than 3.5km from the exchange. Some areas are fitted with pair
gain equipment that also restricts ADSL availability.
The earliest days of ADSL in Australia have been marked
with chronic unreliability. The Telstra service had a habit of breaking-down
for hours (even days) at a time. These problems appear to have eased in recent
months. A major advantage with ADSL is that it will run on your
existing phone line. You dont need any cables run into your home. However
it will not run through Commander, PABX and FAXstream systems. ADSL is the most competitive broadband option. While Telstra
is the biggest, many companies are now offering their own ADSL service. ADSL
coverage is patchy at the moment but growing fast. Pacific
Internet As the name suggests, satellite broadband carries the
signal via a satellite. This gets around the problem of not having cable or
ADSL capable phone exchanges. But does have its own disadvantages. The cheaper satellite option uses the satellite to send
the data to you, while you send your data through the phone line. This slows
the connection and can be expensive for a rural customer. The other option is two-way satellite. While this overcomes
a lot of the drawbacks with one-way satellite This can be very expensive should
you go over the download limits. It is, however a realistic option if you
are in an area where ADSL and cable arent feasible. Ihug
Satellite As the options and competition for broadband grow, the
broadband industry is developing like the mobile phone business with a confusing
array of plans. Generally there will be a connection fee that will include
a modem and a technician setting up your system. This fee varies depending
on the term of the plan you sign up for. Generally, the longer you commit
to, the cheaper the up-front charges. Like a mobile phone plan, the biggest trap for users are
the excess-download fees. These can easily run into the thousands of dollars.
When shopping for a plan it is worthwhile asking if the
provider has a usage meter so that you can check the downloads. It is a good
idea to find if it is easy to change plans should you find the plan is too
expensive. Even if you think you wont use much, remember you
will use it a lot more than you would a dial-up account. Every e-mail, every
webpage, every moment of audio and video counts towards your total. It is
very easy to exceed 300Mb in a month as many people find when they get their
bill. With a faster, always on connection broadband changes
how you use the Internet. As broadband becomes cheaper and more accessible
we will see more people getting it. At present, the pricing and availability
is restricting its use. The best guide to Australian broadband services is The
Whirlpool. We highly recommend it, not just
for broadband but for general Australian Internet issues.Cable
