Indoor propagation measurements at 900 MHz

Narrowband propagation measurements were made inside a rectangular office building with inner walls of thin plaster board and floors of reinforced concrete. The propagation characteristics were divided up into four components: the global path loss, slow fading, fast fading, and the influence of the human body. The last component was investigated by holding a pocket phone close to the head or chest while moving. The global path loss was calculated using the mean signal strength in each room and compared to a statistical model. The propagation behavior in transition zones, e.g., the area around doors and corridor corners, was also studied. The narrowband measurements were made in a modern office building
