Pathloss and shadowing
If the transmit power Pt is 50 mW, the gains of the transmitter and receiver antennas are 10 and 5 respectively, and the wavelength is 0.15 m, what is the received power at a distance of 5 m?
How does the distance between the transmitter and receiver affect the measured pathloss in your experiment?
If the combined antenna gain is 100 and the distance between transmitter and receiver is 100 m, how would the pathloss change if the distance increased to 200 m, assuming frequency and wavelength remain constant?
In the Friis transmission equation, which parameter most directly accounts for the frequency dependence of pathloss?
Which of the following best explains why higher frequencies experience greater pathloss in free space?
If the measured received power is lower than the value predicted by the free space pathloss model, which of the following is the most likely cause?
In a log-distance pathloss model, the pathloss exponent n typically:
Which measurement setup would likely produce the smallest pathloss in your experiment?
