A two-way radio is a communication device that allows users to both send and receive voice messages. Unlike traditional telephones, which rely on cellular networks, two-way radios use radio waves to transmit signals over short to medium distances. They are commonly used in situations where quick, reliable communication is needed, such as in emergencies, by security teams, or in construction sites. Two-way radios are typically portable, with a push-to-talk button for transmitting and a speaker or earpiece for receiving messages. They are valued for their simplicity, durability, and the ability to work without needing a phone network.A two-way radio is a communication device that allows users to both send and receive voice messages.
