ABSTRACT

To access the internet we need the broadband connection or fast dial up connection. Unfortunately, this has been held back by the high expenses of wiring infrastructure essential to deliver such high-speed internet access especially to private homes, small offices and rural areas, where the installation of any kind of new wires tilts the scales of the economic feasibility to a non-profitable state.

But if broadband could be served through power lines, there would be no need to build a new infrastructure. Anywhere there is electricity there could be broadband. Broadband over Power Line (BPL) is a technology which allows transmission of data over the same lines used to transmit electrical power. A computer (or any other device) would need only to plug a BPL "modem" into any outlet in an equipped building to have high-speed Internet access. BPL may offer benefits over regular cable or DSL connections: the extensive infrastructure already available appears to allow people in remote locations to access the Internet with relatively little equipment investment by the utility.


INTRODUCTION


After years of development, technology to deliver high-speed data over the existing electric power delivery network has emerged in the marketplace. Called broadband over power line (BPL), this technology offers an alternative means of providing high-speed internet access, Voice over Internet Protocol (VoIP), and other broadband services, using medium- and low- voltage lines to reach customers’ homes and businesses.

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.
