What defines a two-way radio?

A two-way radio is defined as a device that can both transmit and receive signals. This capability allows for two-way communication, meaning that individuals can send and receive messages back and forth, which is essential in various professional and personal contexts. This type of communication system is widely used in law enforcement, emergency services, construction sites, and other settings where immediate and direct communication is required.

In contrast, devices that only receive signals cannot facilitate interactive communication, which is a fundamental aspect of two-way radios. Similarly, a device that is exclusively used for broadcasting lacks the ability to receive or respond, further distinguishing it from what constitutes a two-way radio. A device that cannot communicate at all falls outside the definition since it fails to meet the basic criteria for functionality in communication. Therefore, the characteristic of being able to both transmit and receive is crucial for identifying a two-way radio.
