How is 'bandwidth' defined in the context of wireless communication?

In the context of wireless communication, 'bandwidth' is defined as the range of frequencies that a communication channel can use for transmission. This definition reflects the capacity of the channel to transmit data, which is crucial for determining the amount of information that can be sent over a wireless connection in a given time period.

Bandwidth is measured in hertz (Hz) and indicates the width of the frequency spectrum available for communication. A wider bandwidth allows for more data to be transmitted simultaneously, leading to higher data rates and improved performance in wireless systems. In essence, bandwidth directly influences the efficiency and speed of wireless communication systems, making it a critical factor in network design and technology.

Other options, such as the total number of users a channel can support or the strength of the signal received, describe different aspects of wireless communication but do not accurately define bandwidth itself. Similarly, the duration of data transmission refers to time rather than frequency characteristics, distinguishing it from the proper definition of bandwidth.
