# Bandwidth vs. Frequency: What's the Difference?

Edited by Sawaira Riaz || By Sumera Saeed || Updated on October 19, 2023
Bandwidth refers to the range of frequencies in a signal; frequency is the rate at which a signal oscillates.

## Key Differences

In communication systems, both bandwidth and frequency play crucial roles, yet they serve distinct purposes. Bandwidth is a measure of the range of frequencies over which a system can operate effectively. It quantifies how much data can be sent through a network or a channel, usually expressed in terms of Hertz (Hz) or bits per second (bps). Conversely, frequency denotes the rate at which a signal or wave oscillates in a given period. It's expressed in Hertz (Hz) and determines how often a signal completes one full cycle.

For instance, when discussing radio signals, bandwidth might describe the span of frequencies allotted to a radio station, while frequency will refer to the specific central frequency at which the station transmits.

From a broader perspective, bandwidth can be seen as the width of a channel on the frequency spectrum. In contrast, frequency is a specific point or location within that spectrum.

While bandwidth can give an idea of the capacity or space available for data transfer, frequency is more about the position and repetitive nature of a signal.
