A transmission environment in which communication can occur in both directions, but is required to alternate direction. This kind of transmission environment is also known as two way alternate. Alternatively, a transmission system in which a participant is permitted to transmit and receive, but never simultaneously.

Example half duplex environments include Ethernet over coaxial cable and walkie-talkie "push-to-talk" wireless communications.
