Some time I wonder how this small toy known as cell phone mobile connects to communicate two persons at far distance from each other. Still I am unable to understand how this cell phone works. Can any one you tell me in detail that, what is the technique behind the cell phone to connect two people. On what technology does it works. I know this information will not going to promote my business at all, but still helps me to up date my knowledge. Waiting for all you valuable explanations.
