From Electromechanics to Electronics

The applications of the properties of electromagnetism in telecommunications in their early stages were mainly based on the properties of electromechanics.

What is electromechanics?

A field that combines electrical and mechanical properties to create systems that convert electrical energy into mechanical motion (or vice versa).

In telecommunications, electromechanical systems such as Strowger's dial famous have been used since the 19th century for transmission, switching and amplification.  These systems rely on moving mechanical components that operate on electrical signals, such as relays, switches, motors and electromechanical transducers.

The transistor enters our lives. The electronic

The transistor marks a new era in the technological evolution of telecommunications & technology. We are now moving into the electronic age. Electricity no longer functions, not only as a "motor" for mechanical components, but the control of the current intensity and flow itself are elements of the operation of telecommunication devices. Telex, digital telephones, digital computers!

The transistor is changing our lives. Telecommunications & Information Technology

 A typical example of the meeting of telecommunications & IT is Voice over IP (VoIP). Telephony goes through our favourite computer!  The transistor was and is the reason for this development. In telecommunications, electronics replaced electromechanical systems, enabling faster, more efficient and miniaturized communication technologies such as fiber optics, wireless networks and digital data transmission.
