Understand the Difference Between Simplex, Half Duplex & Full Duplex Communication

We live in a hyper-connected world where communication is the key to business success. From hand-written letters to emails, from phone calls to video conferencing and from walkie-talkies to cellular push-to-talk apps, communication has greatly evolved to facilitate instant global connectivity. As more and more businesses rely on mobile devices to keep their field workforce connected, push-to-talk apps are gaining popularity.

If you have worked in the field, or if your business has a field workforce then you must already be familiar with the term push-to-talk. It is a half-duplex communication mode that is used by devices such as walkie-talkies and land mobile radios. But what does half-duplex mean? If walkie-talkies work on a half-duplex mode of communication, then does a full duplex exist too? Let’s understand the various modes of communication.

What is Simplex Communication?

Simplex communication is a uni-directional mode of communication in which two devices are connected, but only the sender can transmit messages and the receiving end can simply listen. This mode of communication creates a one-way channel for information transmission.

What is Half Duplex Communication?

Half-duplex communication is when two devices are connected, and both the sender and the receiver can communicate, but not simultaneously. It is a bi-directional mode of communication in which the sender and receiver can transmit voice messages one at a time.

What is Full Duplex Communication?

Full-duplex communication is a bi-directional mode of communication in which both the sender and the receiver can communicate simultaneously. Unlike half-duplex communication, full duplex communication can establish a continuous two-way connection.

Direction of communicationIt is one-way communication in which only the sender transmits the message and the receiving end hears the message.It is two-way communication in which both the sender and the receiver can transmit messages, but one at a time.It is two-way communication in which both the sender and the receiver can transmit messages simultaneously.
Sender & ReceiverThe sender can only send the data but not receive it.Both sender and receiver can send and receive the data.Both sender and receiver can send and receive the data.
BandwidthSimplex communication makes full use of a single bandwidth.Half-duplex communication makes lesser use of a single bandwidth in comparison to full-duplex mode.Full-duplex communication doubles the use of transmission bandwidth.
PerformanceYields a lower performance compared to half and full-duplex modes.Yields a lower performance when compared to the full-duplex mode of communicationYields the maximum performance as it makes use of double the bandwidth.

Why Is Half-Duplex Communication Ideal for a Field Workforce?

While most of the corporate world enjoys the benefits of full-duplex communication, some industries with a field workforce find cellular phone calls cumbersome and futile. Industries such as construction, warehousing, logistics and transportation, etc. have a field workforce that operates from remote, high-risk environments where speedy communication is critical. Two-way radios such as walkie-talkies leverage half-duplex communication to offer instant push-button connectivity.

The field workforce functions in hazardous locations and operates heavy equipment. Here are some reasons why half-duplex communication outstands full-duplex communication for field employees:

Closing Lines

While simplex communication may be the best choice where a response is not critical, full-duplex communication is largely preferred for modern-day corporate communications. However, with the growing number of field services, half-duplex communication is regaining its limelight. When critical factors such as productivity, operational efficiency, customer satisfaction and business growth are dependent on effective communication, enterprises must carefully pick what works best for them.
