In the development of a new wireless communications system, a versatile and accurate radio channel for indoor communications is needed. In particular, the investigation of radio transmission into buildings is very important. In this letter, we present an improved three‐dimensional electromagnetic wave propagation prediction model for indoor wireless communications that takes into consideration building penetration loss. A ray tracing technique based on an image method is also employed in this study. Three‐dimensional models can predict any complex indoor environment composed of arbitrarily shaped walls. A speed‐up algorithm, which is a modified deterministic ray tube method, is also introduced for efficient prediction and computation.
