Cordless phone is a part of a two-piece gadget that has a handset and a base unit. A cordless phone is based on the principle of the radio. It uses high frequency radio waves to transmit and receive signals. These signals are decoded into sound and made audible. Base unit is connected to the main phone jack and an AC power cord is needed to charge the handset. Base unit receives incoming calls via phone line and coverts it into FM radio signals. This is then transmitted to the handset, which decodes these signals. Once the handset receives radio signals from the base, it is converted into electrical signals and thereafter decoded as digital sounds. While speaking on the handset, voice is converted into signals and sent to the base unit through an FM signal. Base unit then converts it in to an electric signal and transmits it through the phone line to the caller. Briefly, this is the procedure on which a cordless phone works. Range of cordless phones is dependant on the strength of the frequency at which signals are received and transmitted. Higher frequency leads to better sound quality and range of function.
