Abstract
With the advent of 5G mobile communication and researches on propagation of large-scale channel modeling for frequencies above 6 GHz, measurement campaigns were performed at 10 GHz with horn-type directional antennas in a corridor and a computer room within the Electrical and Computer Engineering Laboratories’ first floor, at Federal University of Pará (UFPA), Brazil. This paper presents data obtained through said campaigns, channel modeling with co-polarizations V-V and H-H and cross-polarization V-H in line-of-sight (LoS) or non-line-of-sight (NLoS) conditions. The large-scale Close in Reference is sustained by a comprehensive analysis, considering propagation mechanisms such as reflection and diffraction. Results demonstrate that the established model had inferior standard deviation in relation to measured data, proving itself more significant to propagation in indoor environments.
