When trying to decide what Clear-Com wireless is right for you, the number of users you have and how they need to talk and listen to each other may be the determining factor of what system you need. Today, we will discuss the number of channels section of the Choosing the Right Wireless Infographic.

Before we get into the details of what system will work for you, we need to explain the three different types of communication channels.
A simplex communication channel only sends information in one direction – from the sending device to the receiving device. Simplex is used only when the sending device does not require a response from the receiving device. For example, a radio station usually sends signals to the audience, but never receives signals from them; therefore, a radio station is a simplex channel. Another example is a microphone to a loudspeaker.
In half-duplex mode, data can be transmitted in both directions, just not at the same time. At a certain point, it is a simplex channel whose transmission direction can be switched. Two-way radios are typical half-duplex devices. It has a push-to-talk (PTT) button, which can be used to turn on the transmitter, but turn off the receiver. Therefore, once you push the button, you cannot hear the person you are talking to but your partner can hear you.
A full-duplex communication channel transmits data in both directions at the same time. It is constructed as a pair of simplex links that allows bi-directional simultaneous transmission. Take the telephone as an example. People at both ends of a call can speak and be heard by each other at the same time because there are two communication paths between them. Thus, using the full-duplex mode can greatly increase the efficiency of communication.
Ok, now that you understand what kind of communication you need to have, simplex, half-duplex or full-duplex, you’re now ready to compare wireless systems based on this requirement.
