carrier communication的意思|示意

Carrier communication refers to the transmission of data between electronic devices through a physical medium, such as a wire or fiber-optic cable. It is often used to transmit digital data, such as audio and video. Carrier communication has been the cornerstone of modern telecommunications systems since the development of telephone networks in the late nineteenth century.

In telecommunications, a carrier is simply a medium that enables data to be sent and received. The most common type of carrier is a wire or cable, but radio waves and other forms of electromagnetic radiation are also used as carriers. The type of carrier used in a particular application will depend on the required characteristics, such as data rate, range, and cost.

The actual data that is sent over a carrier is known as the carrier signal. This is typically a digital signal containing some form of encoding that allows the receiving device to understand its content. Examples of carrier signals include modems, which are used to transmit digital signals over telephone lines, and satellite communications, which use microwaves as the carrier.

Carrier communication is also used in wireless communication, such as Wi-Fi networks. In this case, the carrier is typically an electromagnetic wave such as radio or microwave. The signal is modulated onto the wave and transmitted over the air. At the receiver, the signal is demodulated and the data is extracted.

In summary, carrier communication is the transmission of data between electronic devices through a physical medium, such as a wire or fiber-optic cable. It is most commonly used for digital signals such as audio and video, but it can also be used for wireless communication.
