How Mobile Phone Works – How does Mobile Phone work

According to an estimate, there will be about 4.8 billion mobile users by 2019. Today everyone understands the importance of mobile phones. It can make us talk to any person in any corner of the world, but have you tried to know how your cell phone works.

Simply put, a mobile phone is a two-way radio. In which there is a transmitter and another receiver radio. When you are doing it with your friend, it converts your voice into electrical signal. After which it is transmitted in the form of radio waves to the nearest cell tower. Now the network of that cell tower sends the radio wave to your friend’s cell phone. It is converted into sound by converting it into an electrical signal. Mobile phone is based on walkie-talkie itself. But it evolves from it. In which the main work is to make and receive calls, but apart from this, there is a separate InternetThere is also multimedia and camera. Smartphones have been developed now that the computer that can do the work, even a smartphone can do almost all that work, except for a few things.

Process of working of Mobile Phone

Let us know a little how this mobile phone works.

Radio Waves

Mobile phones use radio waves to communicate. What we talk transmits those sounds in the form of radio waves, electric and magnetic field, which we call electromagnetic field. Radio waves carry all the data with the speed of light. The radio wave that comes out of the mobile spreads in every direction and while reaching the tower, whatever things are found in the middle, they also absorb or reflect the radio wave.

Let us understand this through an example. When we are talking by putting the mobile in our ear, then the radio waves emf keeps spreading there continuously. Half the radio waves go inside our body and head, in this way most of the emf is wasted in vain. Some mobile phones have only one antenna that performs both transmit and receive functions alone and some mobile phones have separate antennas for all three.

Connectivity

A mobile phone is a device that is a 2 way wireless communication device. That is, it receives and sends signals. The amount of signal that the tower receives is called signal strength. You know this strength very well in your phone. And sometimes it is said in such a way that I have a full tower or sirf is only one tower. The power of the signal decreases with the distance. Due to low signal, you will definitely find that your mobile battery drains very quickly. This happens because the mobile tries hard because of the weak signal to send the signal to the tower. This is the reason why having a good network is also good and the battery also lasts well.

Antenna

Every cell phone must have an antenna that receives and transmits radio signals. Antenna itself converts the electrical signal into a radio wave and simultaneously converts the radio wave into an electrical signal.
