Frequency Band
A frequency band is a designated range of frequencies within the electromagnetic spectrum, typically measured in hertz, used for transmitting signals like radio waves or data. In today's interconnected world, these bands are regulated globally to prevent interference, enabling everything from smartphone calls to satellite communications without chaos.
Did you know?
The FM radio band, established in the 1930s, uses frequencies between 88 and 108 MHz and can carry high-fidelity sound because it is less susceptible to static than AM, thanks to its wider bandwidth—yet it's astonishing that this band was almost abandoned in favor of television before Edwin Armstrong's innovations saved it. This decision has influenced modern broadcasting, with over 60% of radio listeners worldwide tuning into FM stations today.
