An efficient representation of combined indoor/outdoor 3D mobile radio-coverage

This paper describes an efficient method for visualizing the simulated received power levels at a specified site in the form of equipower scatter plots. This approach provides an easy way for inspecting the actual radio-coverage limits of a mobile network, for a specified reception threshold. For an increased degree of accuracy to be achieved, a ray launching technique has been implemented for the propagation simulations. The representation is applicable to both indoor and outdoor applications.
