• The receiving machine converts the signals and uses a printer (usually built in) to create the copy of the message that was sent. 
• Radio technology is applied in mobile phone. It is a type of radio having two way communications. A cell phone carries a radio transmitter and a receiver inside it. It sends and receives the message in the form of radiowaves.

• Cell phone network system consists of cells and Base Stations (BSs) and Mobile Switching Centre (MSC). A base station is a wireless communication station set up at a particular geographical location. The geographical area covered by a single base station is known as a cell. The group of cells forms a cluster.

•  All BSs within a cluster are connected to a MSC using land lines. The MSC stores information about the subscribers located within the cluster and is responsible for directing calls to them. When a caller calls another cell phone, sound waves of the caller are converted into radiowaves signal.

• This radio signal of particular frequency is sent to the local base station of the caller where the signal is assigned a specific radio frequency. This signal is then sent to the base station of the receiver through MSC. Then the call is transferred to the cell phone of the receiver. Mobile receiver again changes the radiowaves into sound.
