Abstract: Based on 5.25 GHz wideband channel measurements performed in indoor office environment, empirical path loss models in in-room line-of-sight (LoS), room-corridor, and room-room non-line-of-sight (NLoS) propagation conditions are developed for future wireless radio systems. One-slope and dual-slope log-distance models are adopted in in-room LoS and room-corridor conditions, respectively. In room-room NLoS condition, we propose the enhanced attenuation factor models: AF-extended and AF-linear models to further explore the effect of medium walls, heavy walls and doors. This work offers valuable propagation measurements in a frequency range that is being considered allocating to IMT-advanced systems.
