Power Line Communication

• EE 400
• Term Project

2
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.

3
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.

4
Some control networks in power line communication

• CEBUS
• LonWorks
• LnCP
• HNCP

5
CEBUS

• LAN network provides communication between of
  control information and services among devices.

6
LonWorks

• 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

7
LnCP

• A peer-to-peer communication model is used in
  this network.
• it is a multi-master system

8
HNCP

• 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 .
