What Factors Affect AM And FM Radio Reception? Background Information Communications are carried by waves. One type of communication is AM and FM radio. AM and FM radio’s use radio waves. A radio wave is an electromagnetic wave propagated by an antenna at various frequencies. In AM (amplitude modulated) radio waves‚ the audio signal changes the amplitude of the carrier wave. In FM (frequency modulated) radio waves‚ the audio signal changes the frequency of the carrier wave. Australia’s broadcast

Mobile phone tracking tracks the current position of a mobile phone even on the move. To locate the phone‚ it must emit at least theroaming signal to contact the next nearby antenna tower‚ but the process does not require an active call. GSM localisation is then done bymultilateration based on the signal strength to nearby antenna masts.[1] Mobile positioning‚ i.e. location based service that discloses the actual coordinates of a mobile phone bearer‚ is a technology used bytelecommunication companies
