The principle is basically simple, because your mobile phone transmits a certain amount of radio signal, whatever base station nearest to you will capture its presence. Therefore, this gives you an Â“always onlineÂ” mode ready to receive calls and texts.
When another mobile phone user wants to contact you, his mobile phone will transmit a signal to the nearest base station in his location. This base station will then transmit to a series of telecom relay equipments such as channel towers or satellites until it reaches your local base station wherever you are.
Mobile phones are small radios imbedded with mini transmitters. This means that it actually transmits radio signals when powered on. This is a very important component because it readily gives up your electronic radio location so that calls can be diverted to you or make them.
When you change your location, you go out of a single cell and enter a new one. With each change in locality, the base station nearest to you will provide you a signal. In some cases, you may arrive at a location when no signal from any base stations is present; this is called a dead spot.
Basically, the mobile phone is a radio. It relies on a radio signal in order to transmit and receive voice and data information. Previously, the radio device can only receive a signal from a commercial station making it a one way communication apparatus.
