  • Cell phone works on the principle of radio frequency transmissions. For the same reason, it can also be called as a sophisticated radio. These transmissions take place from one base station to another. A base station is also called mast or antenna and is a wireless communication station set up within a particular geographical area. The geographical zone covered by one base station is called a cell.
  • When you make or receive any call, you send or receive a radio transmission. Once you have placed a call, the cellular system identifies your cell phone and provides identity to your frequency. The identity details include the particular phone number and the location details within the system.
  • When you call a person, you send a signal from your phone to the base station of the particular cell phone to which you are making a call. The signal travels along the specified geographical zone and once it reaches the base station, it is given a specific radio frequency channel.
  • After complete processing of the signal, it is directed towards a call switching center. From this stage, the call is transferred to another cell phone directly or through local carrier of the phone. Although it seems little complex, this whole process takes just a fraction of seconds to complete.
  • Population in a specific area defines the size of the cell. If the population is high, the cell size will be small and vice versa. Therefore, in urban areas, cell size is smaller in comparison to rural areas.
  • Cell phone is an extremely important device for each of us today and a good knowledge about the working of the same will bring us more close to this incredible technology called cell phone!
