What is a half-duplex transmission?

There are two types of communication channels – full duplex and half duplex. Duplex, in terms of transmission, means the capability to send and receive data. In a full-duplex communication channel, a device is able to perform a bi-directional data transmissions at the same time.

On the other hand, half duplex transmission devices can transmit data only in one direction at a time. So, data can move in both directions, but one direction only at a time. A walkie-talkie is an example of half-duplex transmission device. Thus, to communicate with someone, you press the ‘Talk’ button and wait for the reply. The person on the other side does the same. Neither of you can talk at the same time.

The half-duplex intercom system with wire offers clarity, security, and reliability. So, unlike wireless systems, there is no threat of hacking because everything is wired together, and the signal is not prone to interference.
