Questions and Answers

What is the formula to calculate total attenuation from rain?

  • $A = \alpha + L$
  • $A = \alpha L$ (correct)
  • $A = \alpha / L$
  • $A = L - \alpha$
  • What parameters are needed to predict link performance in rain?

  • Rain rate, specific attenuation, polarization
  • Rain rate, path length in rain, statistics of heavy rain at site location (correct)
  • Path length in rain, frequency, drop-size distribution
  • Rain rate, temperature, humidity
  • How is attenuation due to rain modeled?

  • $\alpha = aR^b$ dB/km (correct)
  • $\alpha = a - bR$ dB/km
  • $\alpha = a + bR$ dB/km
  • $\alpha = a / bR$ dB/km
  • For an effective slant path length of 5 km, what is the attenuation if rain rate, $R$, is 50 mm/hr, frequency, $f$, is 2.5 GHz, $a = 3.87 \times 10^{-4}$, and $b = 1.31$?
