Indoor-Office Large-Scale Wireless Channel Characterization in cmWave/FR3 Spectrum

This paper presents comprehensive findings on the characterization of Indoor Hotspot channel parameters, derived from an extensive experimental campaign conducted at 6.9, 8.3, and 14.5 GHz in a commercial office building. Extensive measurements were carried out in diverse indoor office settings, including cubicles, conference rooms, hallways, and laboratory spaces across four floors. The path loss, shadow fading, delay spread, and angular spread was modeled. Our results offer significant insights into the attenuation and dispersion characteristics of wireless signals in diverse indoor settings in the centimeter-wave frequency band, and can be used for improving indoor network design and performance in commercial buildings.
