RADIO BANDWIDTHS Meaning and
Definition
-
Radio bandwidth refers to the range or width of frequencies that can be used for radio communication. It represents the amount of data that can be transmitted over a wireless channel within a given frequency range. It is commonly measured in hertz (Hz), which represents the number of cycles per second.
Different radio services operate within specific frequency ranges, known as radio bandwidths. These ranges are allocated by regulatory organizations to ensure efficient and interference-free communication. For instance, the Federal Communications Commission (FCC) in the United States is responsible for assigning and regulating radio frequencies.
There are different radio bandwidths available, each designated for specific purposes. These include:
1. AM Band: Also known as Amplitude Modulation, it operates within frequency ranges of 535 to 1605 kHz. AM is primarily used for medium and long-range radio broadcasting.
2. FM Band: Standing for Frequency Modulation, it operates within the range of 88 to 108 MHz. FM is commonly used for high-quality music broadcasting and has better sound fidelity compared to AM.
3. Shortwave Band: This band operates from approximately 1.6 to 30 MHz and provides long-distance communication across continents.
4. UHF Band: Ultrahigh Frequency band operates within the range of 300 MHz to 3 GHz. It is widely used for television broadcasting, cordless phones, and wireless internet.
5. VHF Band: Very High Frequency band operates from 30 to 300 MHz. It is commonly used for FM radio broadcasting, television channels, and maritime communication.
Understanding the specific radio bandwidths is essential for efficient and coordinated wireless communication, preventing interference between different services and ensuring optimal use of the available frequency spectrum.

Etymology of RADIO BANDWIDTHS
The word "radio" comes from the Latin word "radius", meaning "spoke of a wheel" or "ray", and it was first used by the French physicist Édouard Branly in 1899. The term was later adopted by Guglielmo Marconi, an Italian inventor, to describe the wireless telegraphy system he developed.
The term "bandwidth" is a combination of "band" and "width". "Band" refers to a range of frequencies, while "width" refers to the size or extent of that range. The word "bandwidth" was initially used in the field of electronics and telecommunication to refer to the range of frequencies used for signal transmission or the capacity of a communication channel.
Therefore, "radio bandwidths" refers to the range(s) of frequencies used for radio signal transmission or reception.
