12) Consider a Wi-Fi device that transmits a 0.1 W signal using a 2 dBi antenna. If the EIRP of the Wi-Fi device is 20 dBm. Find the systems and cable losses at the transmitter? Handwritten Calculation Required.
a) 4 dB
b) 3 dB
c) 1dB
d) 2dB
d) 2dB
Calculation: EIRP = Transmitted Power + Antenna Gain - Cable Losses - System Losses
20 dBm = 0.1 W + 2 dBi - Cable Losses - System Losses
Cable Losses + System Losses = 18 dB
Cable Losses = System Losses = 18 dB/2 = 9 dB
Therefore, Cable Losses = System Losses = 9 dB = 2 dB
