A coverage prediction technique for indoor wireless millimeter waves system

In view of the fact that future indoor wireless LAN's are likely to operate in the mm-wave region (20–60 GHz) due to spectrum availability and wider bandwidth requirements, site-specific coverage and channel dispersion prediction need to be made in order to allow maximum capacity in particular situations. This paper introduces a prediction technique which takes into account multiple reflections and diffraction phenomena in an user-specified environment. An efficient 3D ray tracing method is proven to accurately compute all significant paths between transmitter and receiver. Comparisons between predicted and measured results for both wideband and narrowband situations are presented and results show that this technique can be easily applicable in real system engineering.
