Communication Channel

We explain what they are and what are the communication channels. In addition, how they are classified, what they serve for and when they are efficient.

The communication channel can be something as simple as paper.
  1. What are the communication channels?

A communication channel is the physical medium through which a communicative act is carried out, that is, it serves to exchange information between a sender and one or more receivers .

The presence and availability of this specific medium is only one of the essential elements for the communication circuit to be effectively fulfilled . It is extremely important, since every act of communication requires the transmission of information through a specific physical element.

For example, at this very moment, the information contained in this text is reaching its readers after it has been transmitted in a computer network, using satellite signals (microwaves), cables Fiber optic or radio broadcasts (WiFi). These are examples of communication channels.

However, a frequent use of this term, in the corporate world, refers to the routes available to customers of a business in its communication with those who conduct it: electronic mail, phone numbers, message boxes, etc.

In addition to the channel, other essential elements for the communicative act are the code, the sender, the receiver and the message.

In addition: Communication barriers

  1. Types of communication channels

The news media use various mass channels.

Communication channels can be, in broad strokes, of two types:

  • Personal . Those in which communication occurs directly with a receiver, usually one to one, although it may well be one to several. For example, when talking to someone face to face, our receiver listens to us directly, but there could be two recipients in the same situation.
  • Massive Those that allow the same broadcaster to reach a multitude of receivers at the same time, either directly or deferredly, such as mass media: radio, television, written press, etc.

Another classification of communication channels distinguishes between unidirectional and bidirectional channels, that is, if the sender is always a sender and does not assign the turn to the receiver or receivers (such as radio, for example), or if it is a channel reciprocal communicative, which allows the recipients to be emitters also alternately (such as the telephone).

  1. What are the communication channels for?

When the channel does not work, communication is not possible.

As said before, the communication channels are the physical support of the communicative act, its material part. Without them it would be impossible to transmit information . This becomes evident when a communicative channel is indisposed, for example, as occurs when the telephone line is broken and our call is badly heard.

  1. Efficiency of communication channels

A communication channel is more or less efficient, depending on its ability to transmit information reliably, that is, without being lost or adulterated along the way. A simple way to understand this is to remember that game in which the participants are placed in a wheel, and at some point in it a message starts, telling someone in the ear.

That person will say it to the ear the next and so on, until they turn around, without being allowed to repeat or clarify what has been said. Once the message has arrived at the last of the wheel, you should say it out loud, and it will be verified how much of the original message has been lost. That will be an indicator of channel efficiency.

  1. What are the channels of communication?

Microwaves are the channel of telephone conversations.

There are many possible channels of communication. Next, we will detail some examples:

  • The sound waves transmitted through the air, allowing the voice to reach from our sounding device, to the ears of our interlocutor in a conversation.
  • The telephone pulses, with which the old phones operated, or the microwaves with which our cell phones operate, allowing the sound of our voice to be transported from our terminal to the of the receiver and vice versa.
  • Radio waves, emitted by a radio station somewhere in our country, and received by a receiving device capable of decoding them and converting them into sound waves that, through the air, reach our ear.
  • The optical fiber, through which our computers connected to the Internet send and receive computer signals in the form of electrical pulses, traveling long distances back and forth.
  • The paper, in the case of written messages, whether they are a love letter, a news item in the newspaper or a public message that warns that a device is broken and we should not use it.
