BROADBAND OVER POWERLINE
1.0 Introduction
The advancement in the technological developemnet which enables the transmission
of high speed digital data over utility power lines is proposed by the term Broadband over
Power Line. It uses the existing electrical power line as a medium of transmission of data at a
high rate of data speed by coupling the energy of radio frequency over the power line (Held
2016).The technology is implemented by utilizing the principle of power engineering, radio
wave spectrum, network and modem technology along with the electromagnetic
compatibility. The broadband over power line provides an instant access of internet just by
simply plugging the power input of the PC and other devices which provides access to the
internet to the in-house electrical outlet supply. The users have to install a modem which can
be plugged into an ordinary in-house outlet to get access to the broadband services (Singh
and Advocate 2016). Though the broadband technology is increasing rapidly but still a huge
part of the world do not have the access to high speed internet because the cost of cable
laying and constructing the required infrastructure is too expensive in the rural areas, whereas
transmitting the broadband service through the already existing the power line saves a high
expense as well as eliminates the problems of digital divide in the rural areas. This report
discusses about the working procedure of broadband over power line, error code correction
merits and demerits of BPL along with the international standardization.
2.0 Working procedure of Broadband over Power line
In order to provide access to the internet connection at a cheap rate the Broadband
over Power Line uses the power line communication technology over the ordinary power
lines (Dash and Panda 2016). A device can be used just by plugging into a BPL modem
connected to the in-house electrical outlet.

BROADBAND OVER POWERLINE
There are three-tiered power grid hierarchy which comprises of the High voltage,
Medium voltage and Low voltage transmission line. However,the BPL communication
configuration are predominant by two types of transmission line:
i) Medium voltage power line
ii) Low voltage power line
The medium voltage and low voltage power line are used to transmit the internet
signal where a device named head end is used to transmit the signal with the help of fiber
cable. However, the dropped signal over the power line cannot traverse a long distance due to
the distortion or attenuation in the signal strength (Gankov 2018). To avoid such
consequences repeaters are installed over the power lines to enable a smooth transmission of
the data. At last, the end user can get the access over the connectivity of the internet just by
plugging the devices into the BPL modem.
2.1 Technology based on Power Line Communication
The combination of radio frequency with existing electrical medium voltage power
lines generates the functioning of the BPL technology (Artale et al. 2016). The BPL
technology utilizes a method based on high density modulation called Orthogonal Frequency
Multiplexing Division (OFDM) which provides a quality communication to the customers
(Corcoran, Foo, and Lowery 2018). To fulfill the requirements of the customers the upload
and download speed are configured accordingly and delivers the transmission of data at a
high speed to the customers. The BPL technology based system operates over the frequency
range of 10 MHz to 30 MHz which enables the prevention of the signal attenuation (Wen et
al. 2017) . The data usage is optimized throughout the network by keeping the signal strength
more than 30dB.
