Abstract
This invention provides a system and method for efficient ray tracing propagation prediction and analysis. Given a site-specific model of a physical environment, the present invention places virtual obstructions known as reception surfaces within the environment. As radio waves are predicted to propagate through the environment and intersect with or encounter reception surfaces, the characteristics of the radio wave are captured and stored relative to the location of the interaction with the reception surface. The radio frequency channel environment at any point within the site-specific model can be derived through analysis of the radio wave characteristics captured at nearby reception surfaces.
