ADSL

 ADSL allows users to access the Internet through a wireless router. Whereas before ASDL technology was readily available connecting to the Internet required wires attached to the computer running to a modem. Particularly in companies this could be annoying and unsightly because before ADSL was brought out when a new office was fitted out wires would need to be run from every single computer through the wall or along the floor to a single modem to be able to connect to the Internet. Because an individual modem was required per computer due to its low speed connection this could also become highly expensive. ADSL means that only one wireless router is required per office, reducing cost and clutter as well as being much faster.

In the home ADSL has become commonplace. Nearly every home now has a wireless router allowing all forms of electronic communication equipment to connect to high speed Internet. Devices such as laptops, PC’s, iPhones, iPods and Playstations can all connect to the Internet through an ADSL router. This allows large families with 3 or 4 laptops or computers between them to connect to the Internet at the same time with ease. Before this was possible a single modem would have been required per device, which again is costly and if there is only one modem per household trying to get on the Internet could be a struggle.

A downside to ADSL is that it can be interrupted and ultimately disrupted by the simplest of radio transitions. If an individual only has an ADSL router to connect to the Internet then ADSL is perfect and serves it’s purpose. However, if an individual has several wireless devices such as stereos or TV’s that submit wireless signals to speakers etc the ADSL signal can be interrupted and simply stop working. Because of the price people pay for ADSL this can be highly annoying and un-practical. ADSL can also be interrupted by other ADSL transitions that are near by. For example, if a neighbor has a strong ADSL wireless system it could affect your own ASDL system, which again is highly un-practical.

Another issue with ADSL is that due to the way it uses the frequency spectrum. The deployment of ADSL can present some issues. It is necessary to install appropriate frequency filters at the customer's premises, to avoid interference with the voice service, while at the same time taking care to keep a clean signal level for the ADSL connection.
