2. WHAT IS POWER LINE
NETWORKING?
It is an emerging technology.
It is also called as Broad band
over power line(BPL)
Method of home networking to
share printers,internet,etc.
Uses existing ac wiring and
power outlets.

3. WHAT IS POWER LINE
NETWORKING?(CONTINUATION)
Avoids need for putting pc’s near
phone outlet.
Here wires and sockets are
simultaneously used for electricity
and data.
Thus cost effective and one of the
best means of networking
It offers high speed access. 3

4. SCOPES
 Imagine networking your PCs, laptops, printers,
cable/DSL modem, etc. by simply plugging them
into power outlets
 Imagine repositioning your wireless AP for
improved reception by simply moving a device the
size of a deck of cards to a different outlet
 Imaging streaming HDTV from DVD/PVR/set-top
box to any display without adding new wires
 Imagine moving your telephone to any location by
changing where it is plugged in

5. TYPES OF BPL
 In house BPL
 -Electrical wiring is to network computers and
devices within a building.
 Access BPL
 It is a technology that provides broadband access
over medium voltage power lines.

7. FREQUENCY
 Most BPL systems are designed to operate in the
frequency spectrum from 1.705MHz to 30MHz,but
occasionally upto 80 MHz using power distribution
network lines

8. HOW BROAD BAND OVER POWER LINES
OPERATES
 It operates by impressing a modulated carrier signal
on the wiring system
 Accessing BPL consists of :
 Injectors :BPL signals may be injected onto HV
power lines with injectors
 Extractors : provide interface between the medium
power lines and the customers.BPL extractors are
usually located at each LV distribution transformer
feeding a group of homes
 Repeaters :for long runs of HV power
lines,repeaters are employed to maintain the
required signal strength.

9. The signal is received by a power line
modem that plugs into the wall.
BPL modems use silicon chipsets specially
designed to handle the work load of pulling
data out of an electric current.
BPL modem has roughly the size of a
common
power adapter.
 It plugs into a common wall socket, and an
Ethernet cable running to your computer
finishes the connection

10. ADVANTAGES
 High speed Internet Access to Rural areas as well
 Upload speed that’s as fast as your download
speed
 Flexible of modulation
 Simplicity of installation
 No need of a new infrastructure. Anywhere there is
electricity, there could be broadband, so cheaper
 Secure data encryption
 One wire offers both power and high speed
communication needs
 Easy to install

11. DISADVANTAGES
 Electromagnetic interferences
 Every time a device turns on or off, it introduces a
pop or click into line in form of noise
