This work is a collection of new measurement results for indoor channel characteristics in two unlicensed bands. Part of the work is also an extension of another Ohio University student’s MS Thesis [3]. The effects of human movement on the propagation characteristics were not taken into consideration in that work, and that is one of our contributions here. The measurement and characterization of propagation path loss vs. distance on single and multiple floors with and without the movement of people in an indoor environment were performed. It has been observed that the propagation within buildings is strongly influenced by specific features such as the layout of the building, construction materials, and the building type. We have used our measurements and results from a database to estimate building material composition. A widely used propagation model is one in which there is a dominant signal arriving along with many weaker signals: this gives rise to a Ricean amplitude distribution. We have computed the Rice factor from our measurements, using the moment estimation method. We have also made a first attempt to estimate the Doppler spectrum from the signal power samples due to the time variations of the scatterers.
