WebRayTracing objects are propagation models that compute propagation paths using 3-D environment geometry [1] [2]. Represent a ray tracing model by using a RayTracing object. This ray tracing model: Is reasonable from 100 MHz to 100 GHz. Computes multiple propagation paths. Other propagation models compute only single propagation paths. http://duoduokou.com/algorithm/31785948821414080908.html
