Experimental Validation of Lafortune-Lacrous Indoor Propagation Model at 1900 MHz Band

Abstract

With an ever increasing demand for cellular voice and data services, many of the cellular providers are finding deployment of the in-building infrastructure inevitable. The in-building deployments allow for further re-use of the allocated spectrum and hence, they provide one of the most effective ways for increasing the overall system capacity. However, such deployments face some formidable challenges. The performance of the in-building systems depends heavily on the characteristics of the indoor radio channel . Excessive path loss within the building can cause lack of coverage . The indoor mobile radio channel is not easily modeled. The channel varies significantly from one building to the other. Furthermore, the channel depends heavily on factors which include building structure, layout of rooms, and the type of construction materials used.
