Half Duplex Transmission vs. Full Duplex Transmission
Main DifferenceThe main difference between these two modes of transmission is that the half-duplex mode is able to transmit data two ways but one way at a time and the full-duplex is the two-way simultaneous transmission of data.

Difference Between Half Duplex Transmission and Full Duplex Transmission
Half Duplex Transmission vs. Full Duplex Transmission
The half-duplex transmission mode is bidirectional but supports single way communication at a time.
Half Duplex Transmission vs. Full Duplex Transmission
The full-duplex transmission mode is bidirectional and supports two-way communication at the same time.
Half Duplex Transmission vs. Full Duplex Transmission
Data can be sent and received in half-duplex transmission mode, but one thing one time.
Half Duplex Transmission vs. Full Duplex Transmission
Data can be sent and received by both sender and receiver at the same time in full-duplex transmission mode.
Comparison Chart
Half Duplex Transmission | Full Duplex Transmission |
Half Duplex mode of transmission is the kind of communication mode that supports two-way communication but with delay. Data can travel only in one direction at a time. | Full-Duplex mode of transmission is the advanced communication mode that is bidirectional. Data can be sent and received from both directions at the same time. |
Real-life Examples | |
Walkie-talkie. Text message | Instant Chat rooms, Audio Video Calls. |
Performance | |
Better performance than simplex but not efficient as full duplex. | Better performance from both simplex and half duplex. |
End to End Communication | |
Data can be sent or received at a time. | Data can be sent and received simultaneously. |
Direction of Data | |
Bidirectional but once at a time. | Bi-directional communication instantaneously. |
Half Duplex Transmission vs. Full Duplex Transmission
Data transmission modes are basically of three types based on data speed, channel, and delivery. They are also termed as data transmission modes. Half-duplex transmission mode comprises of bidirectional communication but uses a single channel. The data can be sent or received in half-duplex transmission at a time. Whereas the full-duplex transmission mode is advanced of all supporting two-way data delivery at the same time. Data can be sent and received both at the same time.
What is Half Duplex Transmission?
The half Duplex mode of transmission is the kind of communication mode that supports two-way communication but with delay. Data can travel only in one direction at a time. It comprises of a single channel for both sending and receiving the data. Common examples of half-duplex transmission mode include communication via Walkie-talkie. Text message services on the cellular network are kind of half-duplex communication. Half-duplex modes are still in use publicly but are being replaced by full-duplex modes being more efficient and user-friendly.
What is Full Duplex Transmission?
Full-Duplex mode of transmission is the advanced communication mode that is bidirectional. Data can be sent and received from both directions at the same time. It comprises of dedicated channels for both sending and receiving. Common examples of full-duplex transmission mode include telephonic call communication. A modern-day example includes video calling, instant chatrooms, etc. The full-duplex data transmission mode is better in performance from both simplex and half-duplex and is based on the latest technology. Unlike the simplex mode of transmission, full-duplex has two different data communication channels established for smooth data sending and receiving both. Nowadays data and communication are happening via multiple channels and data is transmitted in multiple directions at the same time.
ConclusionHalf-duplex transmission mode is two way but one way at a time and on the flip side full-duplex is two-way data transmission simultaneously.
