Measurements for 2.4 GHz spread spectrum system in modern office buildings

The implementation of wireless communications inside office buildings requires the 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 in 2.4 GHz range. The measurements were conducted within National Technical University premises in Athens, Greece. The purpose of the measurement campaign was to study the radiocoverage of the three-floor story 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 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 being presented.
