Mobile phones transmit and receive signals using radio waves or electromagnetic waves between frequencies of 872-960 MHz, 1710-1872 MHz and 1920-2170 MHz. A mobile phone sends and receives information via radio communication with the nearest base station, which are connected to the network via telephone cables or higher frequency radio links. Each base station provides radio coverage to a geographical area known as a cell.
