How do mobile phones work

<h3> <span style="color: blue;">Lesson 1</span></h3> <h2> <u><span style="color: red;">How does a mobile phone work..........???</span></u></h2> <div> If you want to be a good technician, you must learn how does a mobile phone work till the beginning. </div> <div> <br /></div> <div> Yes...!!! Now we'll see how we can get this step by step. I would like to say this is a funny lesson for me. </div> <div> <br /></div> <div> Actually mobile phones are just like FM radios which we use in the domestics. :) </div> <div> But, mainly a mobile phone has two parts called <span style="color: orange;">Receiver</span><span style="color: lime;"> </span>and <span style="color: orange;">Developer</span>. </div> <div> <br /></div> <div> <span style="color: orange;">Receiver Part:- </span>This part works like a domestic FM radio.
