Large-Scale Channel Modeling and Measurements for 10 GHz in Indoor Environments

Abstract

With the advent of 5G mobile communication and researches into the propagation of large-scale channel modeling for frequencies above 6 GHz, measurement investigation was 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 experimental work, channel modeling with co-polarization 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.

Channel Analysis for 3.5 GHz Frequency in Airport

“…Therefore, the CI method of equation ( 1) is applied for co-polarization H-H, where the PLE (n HH ) is the loss factor with the data in H-H. This is how the P L CIHH is determined [10] .…”

“…Research can be found in the literature on evaluating path loss as a function of distance indoors [10]- [12] and outdoors [13]. In this path loss evaluation, it is of interest to quantify the loss and analyze important parameters, such as the Path Loss Expoent (PLE).…”

“…Moreover, the loss at 3.5 GHz was lower compared to the other frequencies, suggesting better coverage. In [10], the channel at 4.1 GHz is characterized and parameters such as CI model loss are evaluated (with PLE for LOS and NLOS, 1.96 and 2.72, respectively).…”

“…Indoor antenna polarization characteristics are studied in various combinations to evaluate the propagation loss behavior through the radiocommunication channel [10], [12], [14]. Such as [10], measurements are reported using directional horn antennas in the same polarization (V-V and H-H) and in cross polarization (V-H) in LOS and NLOS situations for 8-11 GHz indoors environment.…”

In [12], the "n" approach to evaluate path loss with same-polarization and cross-polarization antennas at 11 GHz is considered, where the PLE ranges from 2.0 to 3.0 for the NLOS case and from 0.36 to 1.5 for LOS.…”
