Answer is 28, this diagram missing (gain 2 dbi) for each Antenna, and (4db loss) for each cable. Receiver = -45dbm

Data: Cable loss transmitter = 4db Transmitter antenna gain = 2dbi Receiver antenna gain= 2dbi Reveiver cable loss = 4db Final Receiver signal = -45dbm FSL = ?????? So, how did you get the answer?
