Advantages and disadvantages of the technology ADSL start by saying that when you connect to the Internet, you can do it through a normal modem, by a local network, a cable modem, or also through DSL technology. The DSL is basically a high-speed connection that uses the same wires to the telephone line of a lifetime. ADSL (Asymmetric Digital Subscriber Line or asymmetric Digital subscriber line) is a technology that allows you to expand the capacity of the traditional copper phone lines in a surprising way and can achieve speeds of up to 20Mbps test. This functionality allows you to do things like watch TV or listen to concerts live, unthinkable with a conventional connection RTB. The advantages that you can provide are: * offers the possibility to talk on the phone while navigating through the Internet network, because, as noted earlier, voice and data work in separate bands, implying separate channels. * Use an existing infrastructure (the basic telephone network). This It is advantageous, both for the operators, who do not have that face large expenditures for the implementation of this technology, as for users, because the cost and the time it takes to have available the service is less than if the operator had to undertake works to build new infrastructure.
ADSL users have permanent Internet connection, not having to establish this connection through dial-up or network signs. This is possible because there are connection point to point, by which the existing line between the user and the control unit is not shared, which also ensures a bandwidth dedicated to each user, and enhances the quality of the servicio.comparativa ADSL. This is comparable with a switched network architecture. * It offers a connection speed much higher than through dialing phone to the Internet. This is the most interesting aspect for users. Some disadvantages that you may encounter are: * a DSL connection works better the closer you are from the telephone exchange of your localization.
