The Wireless Network Infrastructure Required to Transmit Data
The process of sending and receiving radio signals through wireless networks involves two devices, the transmitter and the receiver. The receiver picks up the waves with its antenna or aerial and turns the electric signal back into sound where it can be heard.
To transmit sound by radio, the transmitter adds a high frequency carrier wave to the sound signal. This makes the amplitude of the carrier wave change, but the frequency stays the same. This is called Amplitude Modulation. This form of modulation produces frequencies which are the ‘sum and the difference’ of the carrier and modulation frequencies. These frequencies are sometimes called sidebands.
