Abstract	Summary form only given. The implementation of wireless communications inside office buildings requires a profound knowledge of signal penetration within buildings. This paper contributes to the modeling of propagation losses and measurement techniques in modern office buildings by presenting measurement results at 2.4 GHz. The measurements were conducted within the National Technical University premises in Athens, Greece. The purpose of the measurement campaign was to study the radio coverage of the three-floor building. The measurement procedure involved field measurements of a spread spectrum system. The measurement system and experimental procedures are described and analysis results are presented. Specifically, path loss is presented as a function of the true and covered distance as well as comparative plots for the corridors and rooms of the three floors of the building. Path loss contour plots are also presented.
