How do cell phones work?
Imagine calling a friend on the other side of town. As you chat away, your phone converts your voice into an electrical signal, which is then transmitted as radio waves and converted back into sound by your friend's phone. A basic mobile phone is therefore little more than a combined radio transmitter and a radio receiver, quite similar to a walkie-talkie or CB radio.
In order to remain portable, mobile phones need to have relatively compact antennas and use a small amount of power. This means that mobile phones can send a signal over only a very short range, just like a walkie-talkie.
The cellular network, however, enables you to spread the latest gossip regardless of how far away your friends are. This is done by dividing up land into a patchwork of ‘cells' – hexagonal areas of land each equipped with their own phone mast (also called a base station).
These huge phone masts pick up the weak signal from your phone and relay it onwards to another phone mast nearer to your friend. And if you're on the move while you talk, your phone switches masts as you go without interrupting your call.
Actually our cell has a very tiny antenna inbuilt inside it. Which is capable of generating and receiving signals from a particular band like GSM, WCDMA, CDMA.
Our phone has small processor, RAM and also displays which works as a computer and operates this antenna. So when you are dialing a number like a computer you do give input to it. Then you sy what to do with that number. If you want to call you press call button so it sends a signal to the processor and processor intern sends proper signal to the antenna and the antenna communicates with the network towers(the large BTSs) which again intern connects to your loved ones phone.
Now when you talk there is a microphone to receive it and convert it into electrical signal (work of a transponder) then the signal is boosted with a modulator then sent through the antenna.
In the receiver side the antenna catches the signal a de modulator de modulates the boosted signal and creates the signal understandable by the phone. Then the signal is sent to the speaker which again converts the electrical signal into sound energy.
For browsing the internet the phone uses the computer like approach but the transmission and reception of signals are done by the antenna only.
Do you mean how does a cell reception/ calling works?
When we dail the number and call it .the local towers(base station) receive an incoming message/interrupt then this call is transferred for the tower to the local transmitter which transmitta the cal to the satellite which is received by a receiver which inter transmits the call to the base station in which the mobile is persent. The base station then transmits the call to the requird person. Many protocols are used during this process for ensuring the secrecy. Mostly all calls doenot require a satellite.normal base stations will be enough✌️
A cell phone works along with network for mobile communication. GSM have developed standards for mobile communications. Every node in network uses various protocols. The legacy protocol is ss7 . For more
When we talk into a mobile it converts the sound of your voice to the radio frequency(radio waves). These radio waves are transmitted through the air to a nearby base station.
The base station than sends the call through the telephone network until it reaches the person you are calling. The base station sends out radio waves, which are detected by your telephone and converted back to speech.
The mobile phone network operates on the basis of a series of cells. Each cell requires a radio base station to enable it to function.
