ADSL FEATURES
The ‘ ADSL allows you to have an asymmetric high-speed access through the pair of copper telephone cable that comes into our office. The ‘ ADSL and technology that exploits the existing telephone network allows you to have an advantage over other existing techniques such as cable modem where it is necessary to put in the installation of new cables, with a significant increase in costs. The advantage for the wired lies in the fact that you are using one constant bandwidth and a better quality of service ADSL .

The voice band is 3.1 kHz sufficient for the transmission of voice conversation and multiplexing. The band ADSL uses the frequency spectrum later. The band within the copper pair is thus shared between the telephone frequency with a frequency between 0 and 4 kHz and 4 kHz frequency between ADSL and 2.2 MHz

Wireless ADSL over twisted pair copper requires using 2 modems one downstream, at the user’s premises and one in the middle, through their interoperability is now possible to broadband services. The speed ADSL users can go from 20 MB to users who reside close to the central office to 640Kbps for users who are located more than 5 km from the center. Knowing the distance from the center we are able to determine the theoretical maximum speed that can be supplied by your ADSL .

To find the distance from the center, you can use the tool ” Distance from central “in this section of our tool portale.Conoscendo the distance from our house a DSL central

Below is an example of the spectrum ADSL and ADSL2 , their characteristics, distances to reach.
