| Abstract | The demand placed on the profound knowledge of propagation phenomena and
powerful simulation models will further increase simultaneously with the evolution of wireless
personal communication systems. Improved deterministic propagation models have to be
developed which make the efficient utilization of the geographical information and
identification of dominant propagation paths and their losses.
This paper presents a ray tracing technique to predict path loss and delay spread in
buildings. Ray directions at the transmitter have been found by using the concept of geodesic
domes. Line of sight, specular reflections and transmissions, non specular diffractions have been
included in the propagation model. This method has shown that accurate impulse response,
path loss, and delay spread prediction in buildings are possible using site-specific information.
Modeling refinements are still needed to accelerate the performance as well as to
improve the accuracy of the tool. With such a propagation prediction tool, personal
communication systems could be designed and installed more rapidly and economically than if
measurements were performed for each building |
