As a communications system engineer, you are asked to setup a communication system to serve a distance of 100m using an access point transmitting signals with power 20dBm at the frequency 2.4GHz. The antennas used at the transmitter and receiver side have the gains shown in the picture below. The coaxial cables used to interface the systems to the antennas have losses shown in the picture below What is the received signal power in dBm at the input of the...
