What Makes My Mobile Phone Work?
The mobile phone has been the gadget that closed the 20th century as having the biggest impact on consumer's lives. Millions of people around the globe are constantly using mobile phones to stay in touch with others. By using this pocket size gadget you can talk to anyone around the world just by clicking some buttons. But have you ever wondered how this amazing device works? Here, is a brief discussion on the working of mobile phones.
Mobile phones work as a two way radio system. When you talk through a mobile phone, it converts your voice signal into radio waves. These radio waves travel from the antenna of your mobile phone to the receiver at a nearby base station. The base station then sends your call through the telephone network until it reaches the mobile phone you are calling.
When you receive a call on your mobile phone, the signal travels through the telephone network until it reaches a base station which is close to your mobile phone. The base station then sends out radio waves that are detected by a receiver in your mobile phone, where these radio waves are converted into speech that we hear.
In this entire process base stations are the most important part of the mobile phone networking. The area covered by Base station is known as "Cell", which is hexagonal in shape. When we move from one cell to another "Handover" occurs, breaking connection from the previous base station and making a new one from the current base station which may take some seconds. When all the channels of the base station are occupied, no more calls can be transmitted or received from that particular base station.
Apart from talking, mobile phones are having various functionalities that differentiate it from a regular landline phone like SMS, Web browsing, GPS, games, mp3, FM radio, camera etc. So while sharing your brilliant ideas or just gossiping with your friends via your mobile phone just imagine how it is actually working!
