Consider a 1GHz wireless link which may be characterized by the following path-loss model: P,(d) = P, (do) (do) In (E1.3) the term P, (do) denotes the received power at the reference distance do from the transmitter under free-space condition. For system calibration, a free-space line-of-sight power measurement is taken at reference distance do = 1m from the transmitter using antennas both of 0dB gain. The transmit power is 10mW. Further, assume the noise power at the receiver is - 160dBm. (a) Predict the received power measurement P, at do = 1m . (b) Determine the capacity of the wireless link per Hz at distance d = 750m. (c) Find the maximum distance dmax between the transmitter and receiver such that the received signal power to noise power ratio is at least 20dB.
