Inbuilding prediction [radio propagation]

Potential implementation of wireless radio local area networks and personal communication services inside buildings require a thorough understanding of signal propagation within a building. In this paper an inbuilding prediction tool is presented. It uses a more simplified method than the ray tracing method. The prediction in this tool focuses on a single floor of a building applicable to different floors of the building. A special feature of this tool is its capability to handle different types of obstructions. The tool is validated by gathering the measured data for different floors of a building and comparing them with the predicted values. The standard deviation is within 3 dB. This tool is simple to develop and the accuracy is within expectations.
