CARRIER FREQUENCIES Meaning and
Definition
-
Carrier frequencies refer to the specific frequencies used to transmit electromagnetic signals in various communication systems. In these systems, a high-frequency signal, known as the carrier signal, carries the information that needs to be conveyed. This carrier signal is modulated or altered in some way to encode the data being transmitted, such as voice, video, or digital information.
Carrier frequencies are commonly used in a range of communication technologies, including radio and television broadcasting, cellular networks, and satellite communications. They are chosen carefully to ensure efficient and reliable transmission, while also avoiding interference with other signals.
In radio broadcasting, carrier frequencies are used to transmit audio signals over the airwaves. The audio signal is combined with the carrier frequency, typically in the range of 88 to 108 MHz, and the resulting modulated signal is transmitted through antennas to be received by radios.
In cellular networks, carrier frequencies are used to transmit voice and data signals between cell towers and mobile devices. These frequencies are allocated by regulatory authorities to ensure efficient use of the radio spectrum and prevent interference between different wireless services.
In satellite communications, carrier frequencies are utilized to transmit signals between satellites and ground stations. These frequencies, typically in the microwave range, allow for long-distance transmissions and are carefully coordinated to avoid interference with other satellite systems.
Overall, carrier frequencies play a vital role in enabling effective and efficient communication across various technologies, ensuring the accurate transmission of information over different mediums.

Etymology of CARRIER FREQUENCIES
The word "carrier" in the context of carrier frequencies originates from its usage in telecommunications and radio technology. The term "carrier" refers to a continuous electromagnetic wave that carries or transmits other signals, typically modulated onto it.
The etymology of the word "carrier" dates back to the early 19th century. It stems from the Latin word "carrus", meaning a wheeled vehicle or conveyance. Over time, "carrier" evolved to represent something that carries or transports something else.
In the field of telecommunications, the concept of "carrier frequencies" emerged with the development of modulated waveforms to transmit information. These waves "carry" the smaller, modulated signals, such as voice or data, on top of them. Hence, the term "carrier frequencies" denotes the specific frequencies on which these carrier waves are transmitted.
