- 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. 2 Sunday,17January2016
- 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 Sunday,17January2016
- 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 4 Sunday,17January2016
- 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. 5 Sunday,17January2016
- 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 7 Sunday,17January2016
- 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. 8 Sunday,17January2016
- 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 9 Sunday,17January2016
- 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 10 Sunday,17January2016
- 11. DISADVANTAGES Electromagnetic interferences Every time a device turns on or off, it introduces a pop or click into line in form of noise 11 Sunday,17January2016
- 12. Product Feature Dial up ADSL BPL Customer Benefit Speed Slow Fast Faster Saves time Convenient access No No Yes Convenience, available through virtually all power points Cost Cheap Expensive Cheap Cost effective service Phone/data cabling required Yes Yes No No added costs – no expensive in-house data cabling required or expensive wireless router Access to the Internet Yes Yes Yes Web browsing VoIP phone access included No No Yes Cost savings Integrated Internet and VoIP No No Yes Ease of use and cost savings Always on No Yes Yes Convenience Cheap VoIP calls No No Yes Cost savings, no additional hardware or software required Suitable for video No Some higher speeds Yes Value for money, fun to use COMPARISON 12 Sunday,17January2016
- 13. CONCLUSION Offers a competitiveness to other broadband services. Has potential to become the most ubiquitous broadband network avaliable Secure data encryption Cost effective A future Technology 13 Sunday,17January2016
