Introduction to Wireless Communication Systems

In 1897 Gugliemo Marconi (g.Marconi)  was the first to demonstrate that it was possible to establish a continuous communication stream with the ships that were sailing in the English Channel, by means of radio waves. Since then, the wireless technologies that make “on-the-move” communication possible for us have evolved remarkably. Today, facilitated by RF circuit fabrication and digital switching techniques, affordable high speed telecommunication has been largely deployed across the world.

We know, communication means transfer of information from source to recipient. In traditional telephony, when source and recipient were located in long distance, this transfer used to happen by connecting source and recipient physically through conducting wires, which would carry information in the form of electrical signals.
