This PPT presentation is based on the topic Power line Communications
Power line Communications is very common topic for seminar presentation.
This ppt slide on Power line Communications is a guidline for students or proffesional preparing for seminar presentation on Power line Communications.
Power Line Communication
What is power line communication?
It is a system for carrying data on a conductor.
It uses the existing power lines to transmit data from one device to another.
This makes power line communication one of the best means for networking.
How power line communication operates
It operates by impressing a modulated carrier signal on the wiring system.
Data rates over a power line communication system vary widely.
Some control networks in power line communication
LAN network provides communication between of control information and services among devices.
LonWorks consist of all nodes that communicate with one another over a variety of communications media using LonTalk protocol, a common message-based communications protocol
A peer-to-peer communication model is used in this network.
it is a multi-master system
This protocol provides standard message set of devices.
has to be compact to enable the use of low-bandwidth network media .
The range of devices applying this protocol reaches all the electric machines that are connected by PLC .
