What should the transmission power be to get a received power of at least -75 dBm when transmitting a 915 MHz signal over 3.5 Km. Assume the transmitter has an antenna with a 10 dB gain and the receiver has an antenna with a 3 dB gain. Use the FSPL model described in class. Show all your computations and express your answer in milliwatts. Remember that the free space equation you need to employ is pictured
