All About ADSL in Australia

What should you pay attention to in your choice for an Australian ADSL service? Your search for broadband – any communication media that relays signals from multiple sources at the same time – begins with a look at connection methods and their major drawbacks:

  • DSL is the digital subscriber line that depends upon copper telephone wiring. The copper lends itself to highest frequency vibrations. Its main setback is that you must be close to the service provider’s multiplexers – roughly five and a half kilometers.
  • Cable broadband runs through the coaxial wiring of television cable companies. Its main drawback is a bandwidth that slows down access if many users are seeking service at once.
  • Wireless can be satellite, radio signals, or even microwave technology. The user must be ready for randomly dropped signals or unavailable service.
  • Broadband over power lines (BPL) snagged attention in the news about five years ago, but its interference with radio signals dampened enthusiasm for this technology. Its most popular use these days is to reach rural areas and places not receptive to other signals.
  • Among all methods, DSL’s asymmetric load option, also known as ADSL, provides the quickest downloads and easiest access to the internet. The wireless technology known as WiMax that utilizes microwaves is not yet widely available, but expect that someday it will dominate the market.

Many broadband plans offer you a variety of prepaid megabytes, much the same way as prepaid cell phone service. You’ll commonly see transmission speed expressed as a ratio of download to upload speed. Remember, as you compare plans, that your upload time is often given in kbits, while downloads come in mbits. The mbit is equal to 1024 kbits. The download speed is always quicker; that’s true by definition of ADSL.

When you begin your set-up planning, you’ll be contacting various internet service providers (ISPs) for quotes on cost and service options. You should also let them know what equipment you’re working with on your end to be certain it’s compatible with their multiplexers. Also, let them know if you’re connecting printer, fax, scanner, and so forth. Otherwise, you’ll risk having chronic poor sync rates, which will give you no end to connection problems’and headaches!

Your plan cost will also depend upon the length of your contract. Obviously longer plans will be less expensive. But keep in mind that long contracts prevent you from changing as new technologies become available, which happens frequently in the world of internet and wireless communications. Ask what happens if you cancel – a predetermined cancellation fee or a variable exit fee? Or must you pay fees until the end of your contract?

Most ADSL Australia business plans will charge you based on downstream; the upstream is free. Ask what will happen if you exceed your monthly allotment of downstream: Some companies will charge you extra, and some will continue to provide service although it will be slower than normal.

Expect to find ADSL Australia services available for static IP addresses rather than dynamic ones. This means that your computer has a preset IP address every time it accesses the internet. Routers will enable multiple computers to share one IP address. Cost for dynamic addresses is increased.

You can choose from ADSL1 plans, which transmit in the 25-1100 kbs (kbit per second) range, or ADSL2, which run from 1100kps +. The second option gives you much quicker connectivity but is more prone to attenuation, the degradation of the signal. The distance to your service provider’s multiplexers – the devices which handle the signals – also affects attenuation. Signal to Noise Ratio (SNR) can result from poor quality line or being too distant from the multiplexer.

We advise speed tests to check your signal strength Check Out our main page for ADSL Speed tests in Australia comes highly recommended. Attenuation should measure at 50 decibels or below. SNR should be at 8 decibels or higher. Connectivity issues can vary from the number of devices that share the same line as the computer, to the length of the cord from your devices to the modem, and of course including the quality of your ISP’s line and your distance from the multiplexer. You can also file for line fault adjustments when you’re unable to resolve connectivity issues.
