Objective Basics of radio wave propagation.

Understand fading in mobile propagation channels

Learning outcomes Understand the following topics in wireless channel propagation:
  • Reflection, Refraction, Diffraction and Scattering phenomenon in propagation
  • Attenuation
  • Path Loss
  • Multipath propagation
  • Rayleigh and Rice fading
  • Signal distortions due to fading
  • Lognormal fading - shadowing

Test yourself, answer these questions

  • Explain what is a Fresnel zone and how do I calculate it?
  • What is the difference between Line of Sight and NON Line of sight?
  • What are some of the phenomenon that radio wave experience when propagates in our environment?
  • What is fading? What is fast fading and what is slow fading?
  • What is Rayleigh and Rician distribution?
  • what is dB and what is dBm?
  • What is the Hata Model? What are the main parameters in the Hata Model that affects path loss?
