PLCC (Power Line Carrier Communication) is a network technology mostly used in Telecommunication.
It uses power lines (electricity network supply) as a carrier to transmit signal from one host to another. PLC networks are both electrical supply networks and communication channels at a time. So it has emerged as an economic solution for communication channel and strongly competing WLAN and other network technologies.
Basic principle behind Power Line Carrier Communication is amplitude modulation. At the transmission point a high-frequency (1.6 to 30mhz), low-amplitude signal is superimposed on a low-frequency (50hz), high amplitude AC signal. Power devices do not care about the added noise as filtering devices extract the high frequency signal without low frequency component at the receiver point. In Telecommunication, before transmission of audio signals through the technology audio signals are compressed in the 300 to 4khz range and then modulated with the electrical signals and then filtered and amplified.
These are the devices that used in PLCC Technology:-
1. modem
2. speech interface module
3. data interface unit
4. power supply unit
5. amplifier
6. line filter
An information channel is used in home same like electricity connections as it required one phase and neutral and we can use three different network channels with a three phase electricity infrastructure.. We can also connect these networks using a coupler.
In Brief, PLCC is a handy technique to create a network on an pre existing channel using the concept of amplitude modulation.
