Broadband over Power Line
Broadband over Power Line (BPL), also known as Power Line Communications (PLC) is a disruptive communications technology that enables power line infrastructure landlords (electric utilities & property owners) and their system operator partners to deliver a suite of Internet Protocol (IP) based services using their existing power distribution infrastructure.
BPL transmits high frequency data signals through the same power cable network used in carrying electrical power to household/or business subscribers. In order to make use of BPL, subscribers install a modem that plugs into an ordinary electrical wall outlet and pay a subscription fee similar to those paid for other types of Internet service.
DSL is a very high-speed connection to Internet that uses the same wires as a regular telephone line. A standard telephone installation in the United States consists of a pair of copper wires. This pair of copper wires has sufficient bandwidth for carrying both data and voice. Voice signals use only a fraction of the available capacity on the wires. DSL exploits this remaining capacity to carry information on the wire without affecting the lineâ€™s ability to carry voice conversations. But there are several limitations of DSL describe below :
