What is ADSL

You may have been using internet connection for a long time but have you ever wondered the technology that has been used by the service provider? ADSL is a type of broadband and different from DSL in the fact that it is asynchronous or asymmetric. ADSL is a technique that allows your service provider to send more data to your home using existing copper telephone lines. Internet service provider places a microfilter on the telephone line of the customer. This special filter makes it possible for the customer to be able to use internet and telephone lines at the same time without any disturbance.

 

ADSL provides good downloading speeds

There are two prerequisites for ADSL to work smoothly. There should be a device called modem placed in the home or office of the customer and the office of the service provider must not be too far away from the subscriber’s address. The distance of the office of the company and the subscriber should not be more than 2-2.5 miles in general. ADSL is known to support speeds of 2-9 Mbps when it comes to downstream which is applicable when the customer is browsing the net or downloading something from a website. The speed of uploading or upstream is generally much lower than this and stands at 16-640kbps.

 

The technique of ADSL came into existence to take advantage of the fact that in vast majority of the cases, user is mostly downloading content even if he only browsing the net. This means that the service provider is required to make arrangement in such a manner that information flow is mostly towards the user. The nature of internet is such that a vast majority of users only seek information or entertainment. ADSL cleverly manipulates this nature of internet with the help of ADSL technology.
