Power line access is a technique to deliver data over electrical cables. It is yet another technique to provide high-speed Internet access to home and business users, but the concept has mostly been abandoned. The idea was to run fiber cable close to users, and then use the existing power line cables to connect with user's homes and offices. The systems were supposed to deliver data at multimegabit/sec rates. United Utilities and Nortel Networks were involved in this scheme, but "pulled the plug" in 1999. Other broadband technologies such as DSL and cable modems are considered more practical.
