Frequency

Frequency is defined as the number of times a repeating event happens per second, and is measured in Hertz (or Hz).

When it comes to radio waves, lower frequencies travel farther and can more easily pass through walls and obstructions. Higher frequencies are more easily blocked and are better suited for shorter range use.

To keep radios from broadcasting on top of each other, most of the radiofrequency spectrum is managed by the government and only licensed broadcasters can transmit on a range of frequencies that they “own.”
