Most of us played with walkie talkies as children. These were the forerunner devices to the ubiquitous at-a-distance communications tools to which we have all become accustomed.
An operational characteristic of walkie talkies is that only one person can talk/transmit at a time. If one person is in talk mode (with the transmit button depressed) no others on the channel may contribute.
