Simplex Calls Control in Industrial Communication Systems

The case history started in the 1940s of the last century when the European and American PA/GA and intercom paradigms originated. At the time, industrial intercom and control communication became duplex and simplex. Military application and high requirements to speech illegibility led to the creation of standards for communication in high ambient noise environment. At half-duplex (variation of duplex connection) connection, the built-in echo suppression system automatically controls the direction of the voice transmitting; in this case, communication delays happen as well as loss of speech and parts of important information. These peculiarities caused the development of simplex communication systems and technologies of simplex calls management correspondingly.

Advantages Of Simplex Communication At Industrial Sites

At the current time the simplex type of connection provides maximum ease of use, quality and functional capabilities of industrial intercom systems. It’s due to a number of the simplex mode and the industrial enterprises specifics.

Differences Between Simplex, Duplex And Semiduplex Voice Communication

Industrial communication is one of the most vital types of voice communications as it is directly connected with the safety of sites, personnel and environment. The modern development level of industrial communication technologies allows creating flexible and reliable systems providing various functional capabilities depending on the customer’s requirements.
