Abstract :
For radio propagation prediction, recent simulations involving ray tracing offer unprecedented accuracy. These techniques surpass statistical channel models and provide a bounty of additional information including RMS delay spread, angle of arrival, and overall wideband channel impulse response. In particular, three dimensional ray tracing produces an accurate, deterministic channel model for wireless system design. This paper presents a new 3D ray tracing technique of unprecedented speed and accuracy. Simulation results are compared to microcell measurements at 1900 MHz
