A base station transmits a power of 10 W into a feeder cable with a loss of 5 dB. The transmit antenna has a gain of 12 dBd (dBd refers to a lambda / 2 dipole) in the direction of a mobile receiver, with antenna gain 0 dBd and feeder loss 2 dB. The mobile receiver has a sensitivity of -112 dBm and the operating frequency is 90 MHz. [Hint: OdBd =2.15 dBi rceil a) Determine the maximum acceptable path loss. b) Using the answer from (a) calculate the maximum range of the communication system, assuming the height of the base station transmitter is 30 m, height of the mobile receiver is 1.5m, and that propagation takes place over a plane earth. c) How does this range change if the base station height is doubled?​
