Asymmetric Digital Subscriber Line

ADSL is one of the best places to start if you are looking for a higher speed. Unlike cable, wireless and satellite technologies it transmits via copper wire based phone lines. It can also split a single line into voice and data, allowing users to talk on landlines and still use the internet at the same time; without additional costs of a second line.

ADSL focuses on a higher download speed. This is because most data is normally downloaded instead of uploaded. However, it is not a portable technology, so can only be attached to one phone line. You can’t access that connection from another site.
