Problem

The sensitivity of a commercial GPS receiver is -130 dBm. If the receiver should function within 100 m of a 738-MHz base station transmitting 30 watts of power, how much attenuation of the second harmonic of the transmitted signal is required? Assume free-space loss between the transmitter and the GPS receiver, and that the GPS receiver requires a carrier-to-interference ratio, C//, of 10 dB.
