Long-range walkie-talkies can communicate wirelessly on a single, common frequency band. the battery-powered device includes a transmitter/receiver and a loudspeaker, which also doubles up as a microphone while you’re talking to it, and a button that you’re pressing to speak. The loudspeaker/microphone operates in much the same way as an intercom: since a speaker and a microphone contain basically the same parts, you can use one single tool to do both jobs simply by flipping the electrical circuit through which it is attached and reversing the current. More advanced walkie-talkies have different speakers and microphones in them.
