Measurements of a Dynamic 60 GHz Radio Channel in an Open-Space Office

Résumé

In this work, we study the dynamic 60 GHz radio propagation channel conducted by measurements in an open-space office. These measurements quantify the effect of natural people movements on the path loss before and during working hours. Thus, it's possible to compare the effect produced by these movements with the static case when the office is empty of people. Measurements were performed using a vector network analyzer (VNA) operating on 2 GHz bandwidth. 9900 measures of power loss were recorded over eleven hours of measurements for each receiver position. Five receiver positions were considered to study three cases of receiver positions type the line-of-sight (LOS), the obstructed-line-of-sight (OLOS) and the non-line-of-sight (NLOS). The obtained results allow to compute successively the channel path loss (PL), its probability density function (PDF) and its cumulative distribution function (CDF). Finally we compare the evolution of the dynamic channel in the presence of people at 5.8 GHz and at 60 GHz in the same environment. The dynamic channel propagation measurements provide a statistical characterization for the power loss into a realistic environment and will be useful for the deployment of wireless local and personal area networks (WLAN/WPAN) operating in the millimeter-wave (mmWave) bands. © 2020 EurAAP.
