I have this doubt generally we transmit signals such as mobile signals from one place to other. We see mobiles or devices running on battery getting drained. Why can't we transmit the power signal. Fundamentally I want to know what is the difference between a signal and power signal. Please help.

Technically it is possible but the transmitter power has to be extremely high. The 1Km exclusion zone around every cell station to stop people catching fire is a good reason why it isn't used.

Hi

A cellular phone transmitter maybe works with 5W output power.
The receiver will see maybe nanowatts.

Transmitting Megawatts .... not a good idea, not yet.
