Wireless communication has developed at a high rate. Wireless however is not a new invention.
This is where we can say that modern wireless communication began.
Where can we find wireless now? It is used mostly for broadcasting or communication in
Wireless can be used not only to transmit the data. For example, radars are based on waves.
Where does exactly wireless start? First, we need a device, called transmitter, which has an antenna.
Inside transmitter, there is an oscillator, that is connected to the antenna.
Oscillator creates signal that propagates through the wires to the antenna.
Antenna is a conductor, so signal propagates further towards the end of antenna.
Depending on how fast signal is changing, antenna radiates signal of different frequencies. These frequencies can be used for different purposes like:
In order to communicate using wireless we need more than just transmitter with an antenna.
Signal radiated by the antenna goes into the channel which transports the information and finally reaches the receiver. In order to capture the data, a receiving antenna is required, which intercepts the radio waves and converts them back to the current.
