Statistical characterization of the 900MHz and 1800MHz indoor propagation using reverberation source stirring technique

The comparison of result obtained in both frequency bands and locations reveals a good agreement between mechanical stirring and source stirring. The hallway´s CDF plots agree very well with the theoretical value, a Chi-square distribution with 2 degrees of freedom (DOF). The quality factor in the ETS SMART80 RC is much larger compare to the hallway. This is to be expected and is agreed well with the diameter of the scatter plots for hallway which is much smaller compare the RC chamber because the level of reflection is much less due to the floor, walls and ceiling losses. The successful application of source stirring to characterizing indoor propagation channels will permit reverberation chamber methods to assist in developing channel modeling procedures. Additionally, the impact of loss mechanisms such as apertures and lossy human bodies effect the radiation characteristic for the indoor environment can be studied.
