What does the term "latency" refer to in radio transmission?

Latency in radio transmission specifically refers to the time delay that occurs from the moment a signal is transmitted to when it actually reaches the receiver. This delay can be caused by various factors, including the distance the signal has to travel and any processing delays in the equipment involved in the transmission.

Understanding latency is essential for effective communication, especially in applications where timing is critical, such as live broadcasts or interactive communications. A lower latency means that the transmission is faster, resulting in more immediate communication, while higher latency could result in noticeable delays, which can impact the quality of communication.

The other options pertain to different aspects of radio transmission. Signal strength relates to how well the antenna picks up a signal, frequency range deals with the spectrum of frequencies used, and modulation techniques refer to how the signal is encoded for transmission. Each of these factors plays a role in the overall experience of radio communications, but they do not define latency.
