What is ADSL and why do I need it?


Home and business Internet connections come through multiple channels nowadays, and ADSL is one of these. ADSL is an acronym that stands for ”Asymmetric Digital Subscriber Line.”

ADSL is a high-speed Internet service that uses normal copper-fixed connections to send and receive Internet data, usually at much higher speeds than a conventional dial-up modem can manage. The word ”Asymmetric” refers to the fact that an ADSL connection carries downstream data from the Internet towards your computer at a considerably faster speed than it does upstream data from your computer to the Internet cloud.

With an ADSL connection, you don’t have to dial up to connect to the Internet the way you usually do with a mobile broadband connection. An ADSL is capable of transmitting both voice and Internet data simultaneously, giving you a seamless connection. In essence, with an ADSL connection, you are always connected to the Internet.

How does ADSL work?

ADSL is Internet data that is designed to be carried through your home’s telephone line. To make this possible, a special micro-filter is plugged into your phone connection to separate voice data from Internet data, which allows you to surf the web and use your telephone at the same time.

The reason why the ‘downstream’ lane carries a bigger amount of data than the ‘upstream’ lane is simply because most people do a lot more Web surfing and data downloads than they upload data to the Internet. For people who tend to upload large amounts of information through the Internet (such as business uploading content or sharing large files), a special type of connection known as SDSL, or Synchronous Digital Subscriber Line, which provides a bigger uplink, is available.

ADSL is ideal for heavy Internet users including CAD users, gamers, and people streaming multimedia or downloading large files.

What are the advantages of ADSL over mobile broadband?

One of the biggest advantages of ADSL over mobile broadband is that an ADSL connection provides much faster speeds than a typical mobile broadband connection. A typical mobile broadband connection may provide download speeds of around 550 Kbps – in comparison, a traditional ADSL connection in Australia can achieve download speeds of about 8 Mbps. Ultra-high speed ADSL connections known as ADSL2+ can easily reach download speeds of 20 Mbps.

The second big advantage is that an ADSL connection provides a much more robust and reliable Internet connection than what a typical router or modem can manage. With ADSL you will experience fewer incidences of signal dropouts than with mobile broadband.

ADSL packages are also considerably cheaper than mobile broadband Internet. An ADSL package provides you with a monthly data cap, say 250 gigabytes or 500 gigabytes of data. Once you reach your monthly data limit, you are still able to access the Internet, but at lowered speeds, which makes ADSL ideal for home and business Internet connections.
