Ray-Tracing for Network Planning-I

It’s very easy to get lost in the jargon when selecting a simulation tool for planning your wireless network. You will be faced with complex terminology which would not make much sense. You will be told that ray-tracing is the solution to all problems and outperforms all other techniques. However ray-tracing is only accurate when the following factors have been considered.

  1. Granularity of the terrain database
  2. Granularity in field calculations
  3. Accuracy in representation of building materials
  4. Accuracy in modeling the various propagation phenomenon
  5. Upper limit on the number of interactions
