Indoor wireless channel modeling from 2.4 to 24 GHz using a combined E/H-Plane 2D ray tracing method

Abstract

Future wireless systems are moving to high frequencies for additional bandwidth and frequency reuse. This makes it very important to have accurate and time-efficient models for system planning. We have previously published measurement results for an indoor channel investigation from 2.4 GHz to 24 GHz. We now propose a new combined E/H-plane 2D ray tracing method. This method includes 2D ray-tracing calculations from both horizontal and vertical sections (E/H-planes). The method predicts loss accurately for both line-of-sight (LOS) and non-line-of-sight (NLOS) paths at five frequency bands from 2.4 GHz to 24 GHz. In addition, it predicts the delay spread for line-of-sight paths well, but fails for non-line-of-sight paths.
