What is an ADSL/VDSL line?
ADSL lines leverage the existing copper telephone wiring in homes of users to get an internet connection with a bandwidth significantly. Its technical basis is to pass voice and data through the same telephone line, passing data in a higher frequency than the frequency used in voice communications. Once the line reaches the user, it installs a filter to avoid any inconvenience in telephone conversations frequencies caused by the data.
One feature of ADSL lines is its asymmetry, so download and upload speeds are not the same. Download speed is always superior to upload speed, because ADSL technology is oriented to surfing the web.
VDSL lines are the evolution of ADSL lines with the feature of reaching 30Mbps over copper wires.
What is a SDSL line?
SDSL are technologically the same as ADSL lines, with the difference that in this case they are symmetrycal, so download and upload speeds are the same.
Nowadays, ADSL lines are the most common way to connect to Internet. Their lacks are:
- The lack of coverage in zones away from the telephony central. We can solve this lack using WiMax technology.
- Limit speed of copper lines has been reached, but the fiber optics Network called FTTH will make Internet advance to the next step of its evolution.

You need a copper line to install an ADSL line, if the customer does not have any existing analog line will need to hire a copper line without telephone service which costs 10€ extra per month. In the case of ADSL lines outside the province of Girona always were mounted on a new copper pair, for this reason we have this fixed additional monthly cost.
