How do mobile phones work?

This can be considered as the biggest revolution in the field of communication media, in which human civilization has created a new leap of development. In simple words, we can say that your mobile phone is very much like a radio in which the transmitter and receiver are both (as we often use in Walkie-talkie, etc.) but slightly more advanced than that.

Imagine you call your friend in another city. As soon as you speak here, your phone accepts your voice through a microphone and converts it into an electric signal which is sent through radio waves to another, and your friend's phone calls this signal through the speaker The sound changes. This is the basic principle behind mobile communication, by which you can sit thousands of kilometers away and talk to others.

To make a mobile phone portable, a small antenna is required, which is activated continuously using energy in small amounts. If your mobile phone is switched on and is not in use, then still it sends a signal pulse for a while and this is the reason why your phone consumes very little battery on flight mode because it is the type of signal on flight mode Stops sending and is completely separated from the cellular network.

 What is Mobile?

  • This cellular network facilitates communication with other cell phones located thousands of kilometers away. To create a cellular network, the whole earth is divided into smaller areas which the cells do. These cells are the area of ​​hexagonal size and each cell has its own base station. 
  • When you call cellphone, first of all, the base station in your area captures the weak signal derived from your phone and then relays to your friend's nearest base station. The station then sends that signal to your friend's phone and your voice is heard on his phone.
  •  If you move from one base station to another area of ​​the base station while talking, your phone automatically switches to another base station without affecting your calls and you keep talking.
  • The use of cell solves another complex problem.
  •  The availability of radio frequencies in the phone network is limited and approximately 800 radio frequencies are available at one time. Two frequencies or frequencies are required to call your phone at one time. One to send your voice and to get the second voice. 
  • Thus 400 people can interact at one time but using these cells, these frequencies are re-used on every cell, and in such a number, the same number of people can talk at the same time.
  • For this reason, cellular networks can carry billions of calls per day simultaneously. Whenever a radio frequency is not available in any cell, you are said to be "network busy" but this happens only when there are more than 400 users in the field of a cell. 
  • This is the reason that sometimes, like the number of callers at the new year or another time, and it reaches 400, then other calls are not possible in the area of ​​that cell. In order to avoid this disorder, telecom companies establish intensive cells from densely populated areas so that they are not inconvenient.
