What technology would allow me to send basic information to a receiver and gauge how far away it is?

dkweb101 asked:


My original idea was to use RFID tags but they dont allow me to gauge the distance. Is there any other technology that works in the same way but would show me the distance?

    use radio frequency
    the received power decreases with increase in distance
    at the transmitter callibrate it to transmit signals at a constant power level
    at the receiver use two circuits
    one to receive the data
    other to calculate the received power level

    or try bluetooth but i dont know how you can calculate the distance . the bluetooth system will be integrated
