Signal travels in only one direction from microphone to speaker. This way of transmission can be also called unidirectional or one-way transmission. The half-duplex transmission is capable of sending signal in both directions, but in only one direction at a time. Some networks use half-duplex transmission, but it is required to specify this requirement for all the nodes in the network. An example could be police car radio phones allowing one person talk at a time.

Simplex, Half-duplex, and, Full-duplex Explained This tutorial explains the difference between simplex, half-duplex, and full-duplex.
Simplex Half-duplex Full-duplex It provides one-way communication. It provides two-way communication but one way at a time. It provides two-way communication at the same time. A device can only send data, but it cannot receive data. A device can send and receive data but one at a time.
A device can send and receive data at the same time. It utilizes less bandwidth than half-duplex and full-duplex. It utilizes more bandwidth than simplex but less than full-duplex. It utilizes more bandwidth than simplex and half-duplex. It uses one channel to transmit data. It also uses one channel to transmit data. The entire capacity of the channel is used to send data in one direction. Therefore it is used when maximum bandwidth is required during the transmission.
It is used to conserve bandwidth as only a single communication channel is required, which is shared alternatively between the two directions. It is used when communication in both directions is required all the time without any delays. Full duplex has by far a better performance when compared to both simplex and half duplex.
With half duplex, there is less utilization of bandwidth during transmission. The sender and receiver can both transmit and receive at the same time. Full duplex transmission mode is like a two-way road, in which traffic can flow in both directions at the same time.
For example, in a telephone conversation, two people communicate, and both are free to speak and listen at the same time. Simplex, Half Duplex, Full Duplex.
