I assume that applicability different propagation model for wireless channel depends on the frequency of operation and the kind of obstacles or channel under consideration. My question is can anyone give me a practical situation when the two way ray model is applicable when the operating frequency is say 5 GHz? Link for the two way model is: https://en.wikipedia.org/wiki/Two-ray_ground-reflection_model

  • \$\begingroup\$ There are many situations where it may be applicable. Provided the distance is much larger than the wavelength (almost always the case in wireless point-to-point communications) a ray model is appropriate. The model you gave is appropriate for this along as there are not many obstructions in the way, like say buildings. \$\endgroup\$ – jramsay42 Dec 1 '17 at 7:25
  • \$\begingroup\$ @jramsay42 I am not asking about ray model: I am askng about two way model as in the link. \$\endgroup\$ – Creator Dec 1 '17 at 8:41
  • \$\begingroup\$ It's okay for any large distance, where there is little obstruction between the two antennas. I used to work at a company that made high-speed terrestrial microwave links to remote locations and that model was suitable. \$\endgroup\$ – jramsay42 Dec 1 '17 at 8:44
  • \$\begingroup\$ @jramsay42 Do you remember the frequency of operation please? \$\endgroup\$ – Creator Dec 1 '17 at 9:09
  • \$\begingroup\$ 70-80 Ghz. The only real assumptions the model makes is that you are in the far field and there are only two major paths, which is true in an open environment. \$\endgroup\$ – jramsay42 Dec 1 '17 at 9:19
