Simplex Transmission vs. Full Duplex Transmission: What's the Difference?
Edited by Huma Saeed || By Sumera Saeed || Updated on October 27, 2023
Simplex transmission sends data in one direction only; full duplex transmission allows simultaneous two-way communication.
Key Differences
Simplex transmission is a mode of communication where data can only be sent in one direction, and there's no capability for the receiving end to send data back to the originating source. On the other hand, full duplex transmission allows for data to be sent and received simultaneously, enabling two-way communication between devices.

In simplex transmission, a device is clearly defined as either a sender or a receiver. For instance, a radio broadcast is an example of simplex because the radio station broadcasts the signals, and listeners' radios receive them, but the listeners can't send signals back to the station using the same channel. In contrast, in full duplex transmission, devices can both send and receive data simultaneously, much like a telephone conversation where both parties can speak and listen at the same time.

When using simplex transmission, there's no need for the sending device to wait for acknowledgment or feedback from the receiving device. This might be ideal for scenarios where feedback is unnecessary or not feasible. Conversely, with full duplex transmission, since data flows in both directions, devices can exchange control signals, acknowledgments, and data almost instantaneously.

Applications that require only one-way communication might prefer simplex transmission for its simplicity and straightforwardness. For instance, emergency broadcast systems might utilize simplex. In contrast, applications like internet communication, which involves continuous back-and-forth data exchange, predominantly rely on full duplex transmission for efficiency.
