Modern telecommunication has helped IT Field Engineer learn a series of key concepts that experienced progressive development and refinement in a period of well over a century.
Telecommunication technologies may primarily be divided into wired and wireless methods. Overall though, a basic telecommunication system consists of three main parts that are always present in some form or another: A transmitter that takes information and converts it to a signal. A transmission medium, also called the physical channel that carries the signal. An example of this is the "free space channel".A receiver that takes the signal from the channel and converts it back into usable information for the recipient. For example, in a radio broadcasting station the station's large power amplifier is the transmitter; and the broadcasting antenna is the interface between the power amplifier and the "free space channel". The free space channel is the transmission medium; and the receiver's antenna is the interface between the free space channel and the receiver. Next, the radio receiver is the destination of the radio signal, and this is where it is converted from electricity to sound for people to listen to.
