Telecommunication breakthroughs

Telecommunication is the transmission of signals over a distance for communication. Today, this process involves the sending of electromagnetic waves with the aid of transmitters. Presently, there are several devices are available to aid the telecommunication process. Basic telecommunication systems usually consists of three main elements: a transmitter, a transition medium, and a receiver. The transmitter takes that information and then turn into a signal. A transmission medium is the one in which the signal is transmitted and the receiver acquires the signal and converts it into useful information.
