All You Need To Know About Transmission Modes

Transmission Modes

Data traveling routes have been developed since the inception of technology. With more and more advanced devices coming into place, the data transmission modes are also changing. The transmission media has taken over things and acts as a director for setting up directions for different communication channels. The channel is incomplete without the role of buses and networks, which are designed for communication across different interconnected devices over a network. This article will cover all the transmission modes along with the procedures of how they work. If you are interested in knowing what these modes are and how they work, this article is for you!

What is a transmission mode?

Transmission mode, also known as a communication mode, refers to the channels that bridge two devices to streamline communication. It is a mechanism that transfers data signals between two devices connected over a network. The flow of information greatly differs in the telecommunication world, and the transmission modes tend to define these directions.

Types of transmission modes:

There are various channels where data signals could be transferred. Apart from these channels, the fashion in which signals are transmitted also differs. There are basically three types of data transmission modes used to send signals in different fashions. Each one of these communication modes explained in the coming lines. Are you ready? Let us go through them quickly!

1. Simplex Mode:

The simplest of all is the simplex mode communication system. Two parties are connected over a network, but the communication is unidirectional here. Not both the connected parties can speak and listen simultaneously. The devices that used simplex mode have push-to-talk and release-to-listen buttons. The simplex transmission mode is used for the unidirectional flow of data signals and information.

How does it work?

In Simplex mode, the correspondence is unidirectional, as on a single direction road. Just one of the two devices on a connection can send; the other can only receive. The simplex mode can utilize the entire capacity of the channel to transmit signals.

The mechanism of action is simple. The party who wants to send the signal will push the button to talk. Doing so will close the receiver and turns on the transmitter. Once the message is completed, the sender will release the button. On the other hand, the receiver will have to release the button to keep the receiver on and the transmitter off. Not both parties can communicate with each other at the same time.


The devices that fall under the category of simplex mode are enlisted here.

  • Loudspeakers
  • Television Broadcasting
  • Television and remote
  • Keyboard and monitor

The simplex mode comes with the advantage that it uses all the network’s strength to send a data signal. In contrast, the only drawback of this system is the unidirectional information flow. The system is used in conserving bandwidth since a single data channel is required.

2. Half-Duplex Mode:

Unlike the simplex mode, data signals can transmitted in both directions. Both the connected parties can send and receive data signals but not at the same time. In a half-duplex mode, each station can both send and receive, yet not simultaneously. When one device is sending, the other can only get, and the other way around. The half-duplex mode is utilized in situations where there is no requirement for correspondence in the two ways simultaneously. The absolute capacity of the channel can used for every course.

How does it work?

The mechanism of action is simple. One device can send data signals to the other end using a specific data channel. The same device can receive data signals from the other end on the same channel. The mechanism is a bit different from simplex mode since there was only unidirectional information flow.


A walkie-talkie is the best example of a half-duplex data transmission mode. One party speaks, and the other listens. When one party finishes, the other party speaks, and the first party listens. Both the devices can use the full strength of the network to transmit data signals.

3. Full-Duplex Mode:

Modern-day communication is all about two-way simultaneous communication, and that is what the full-duplex mode is all about. The interconnected devices can send and receive data signals and the same time. The easiest example is a mobile phone conversation, where both parties can listen and speak simultaneously. Unlike the first two modes, the capacity of the network will shared. Signals going in one direction share the link capacity with signals going in the opposite direction.

How does it work?

The mechanism is not hard to understand like the first two modes. We are witnessing and experiencing the full-duplex system in work daily. We talk on mobile phones with our family, colleagues, and friends. Offices use the telephone network to communicate with different departmental heads. All these mechanisms are based on the full-duplex system.


The easiest of examples is a telephone network where both parties can share information simultaneously. The full-duplex data transmission is everywhere, and no one should have any difficulty in understanding how this system works. Telecom companies in Dubai are up to expand the technological landscape using different communication channels.
