What is carrier communication system?
A carrier system is a telecommunications system that transmits information, such as the voice signals of a telephone call and the video signals of television, by modulation of one or multiple carrier signals above the principal voice frequency or data rate.
What is a line carrier?
a carrier (of a line of products): a seller, a distributor, an agent (of a line of products) noun. Right now, you are the exclusive carrier of this year’s new line, so this is the only place anyone can buy it. To carry a line to sell a line, type or range of products.
What is meant by power line carrier communication?
Power-line communication (also known as power-line carrier or PLC) carries data on a conductor that is also used simultaneously for AC electric power transmission or electric power distribution to consumers. Various data rates and frequencies are used in different situations.
How does power line carrier communication work?
The Power line carrier Communication (PLCC) uses the existing power infrastructure for the transmission of data from sending to receiving end. It works in full duplex mode. PLCC system consists of three parts: The 50/60 Hz power transmission line serves as path for relaying data in the PLCC bandwidth.
Is FM better than AM?
The amplitude and phase remain the same. AM has poorer sound quality compared with FM, but is cheaper and can be transmitted over long distances. It has a lower bandwidth so it can have more stations available in any frequency range. FM is less prone to interference than AM.
What are the advantages of power line carrier?
The main advantage of power line carrier communication is the reduced cost because of utilizing the existing power lines. In case of a power supply for a whole building, the main cables are dropped through-out the building and it bears all the load thruster by equipment or devices run on electricity.
Why are carriers used to transmit signals?
The purpose of the carrier is usually either to transmit the information through space as an electromagnetic wave (as in radio communication), or to allow several carriers at different frequencies to share a common physical transmission medium by frequency division multiplexing (as in a cable television system).
What is LMU in PLCC?
LMU is also known as Coupling Device. Together with coupling capacitor, LMU serves the purpose of connecting Audio/Radio frequency signals to PLCC terminal and protection of the PLCC unit from the over voltages caused due to transients on power system.
What do you mean by PLCC?
Power Line Carrier Communication (PLCC)
What does XM stand for radio?
XM. No Modulation (satellite radio)
What do you mean by power line carrier communication?
Power line carrier communication is a method of using the existing power lines for communication, so information can be transmitted by the help of power lines.
How are line traps used in carrier communication?
The line trap or wave trap prevents unwanted loss of carrier signal power and also prevents carrier signal transmission to adjacent power lines. Line traps or wave traps are available for narrow-band and wide-band carrier frequency blocking applications. Where, L is the inductance per unit length in Henry (H).
How are microcontrollers used in power line carrier communication?
Microcontroller: The microcontroller is used to control the home appliances PLCC Modems: The PLCC modem is a power line carrier communication module that acts as a transceiver. In order to control the home appliances, the command is sent by the computer to the microcontroller.
How does a power line carrier ( PLC ) work?
Power Line Carrier (PLC) Signal propagation along high voltage lines depends entirely on the construction of transmission lines, mainly on the configuration and characteristics of all conductors and on the ground resistance optimum coupling allows to make the best use of a given transmission line.
