actually my aim to transmit a power signal and thus the Receiver must receive a signal in the in the following range
voltage= (6-9)v
ampere = (3-12)mV
without amplifying the signal
plz reply.....

 

Power diminishes in proportion to the square of the distance. You ask for 18 to 108 mW power to your receiver. What is your transmitter power output?

 

Hello,

Here are some tools to calculate the range etc.

This question is timely as there is a move afoot to replace traditional ac adapters with broadcast power.

From a PM:

actually i planed to desing a power signal in the range i said

for that i am slecting a sutuable frequecy

i just want to know is bluetooth frequency has capacity to transmitt that range ofr not

(I don't do threads via PM...)

Transmitting power on the Bluetooth frequencies would jam nearby Bluetooth applications, would it not? This would be inconvenient at the least, and would be illegal in many nations.
