A Power Line Communication Network
Infrastructure for The Smart Home
Low voltage electrical wiring in homes are becoming less popular as they are too noisy and unpredictable to support high speed com-
munication signals.The improved technologies like the novel media access control (MAC) and physical layer (PHY) protocols, it is possible to achieve speeds comparable to wired local area networks (LANs) in power line communication networks.
Power Line Communication Application In A Home
Predominantly power lines are used for conveying electrical power to devices. The problems of it are:
-high frequency signals can't pass satisfactoruly
-channel contains noise and interference
- characteristic impedances vary as the medium is made of different materials
-network terminal impedance varies
- Impedance mismatch causes a multi-path effect
ability to record music or videos through a power line, internet, record digital video directly into a PC or even a digital VCR etc are the anticipated applications of PLC.
Internet Bridging
Most of the homes have a internet modem and to share the broadband Internet connection with PLC capable devices, we can adda PLC Internet router to the PLC network. also data exchange with mobile devices can be achieved through cooperation with wireless networks. Mobile devices with wireless capability can talk to devices attached to the power line by making the 802.11x base station PLC compatible. For more details, visit these links:
