Mobile-phones emits small amount of electromagnetic signal via the radio waves which is RF energy. Every Mobile-phone has a low power transmitter in them. While talking over the cell-phone, the transmitter takes the sound of voice & changes it into a continuous sine wave. Sine wave is measured in terms of frequency.Transmitter sends the sine wave to antenna. Antenna transmits the sine wave in the form of electromagnetic signal to the BTS.
