Abstract

The propagation characteristics for the 5G wideband channel based on the path loss model and time dispersion parameters have been presented in this paper. The power degradation has been investigated based on path loss, while the RMS delay spread is used to investigate the time dispersion of 5G channel at 28 GHz frequency for Indoor environment. Extensive measurements have been conducted using wideband channel sounder within 1 GHz bandwidth. Omnidirectional transmitter and highly-directional receiver horn antennas are used for co- and cross-polarized antenna configurations. Results shown that the path loss exponent is 0.9 for Vertical-Vertical (V-V) and 1.8 Vertical-Horizontal (V-H) Polarizations. The mean value for the attenuation factor due to the cross-polarization antenna configuration is 11.9 dB, which represents the discrimination factor (XPD). The time dispersion results found that the Root Mean Square (RMS) delay spread values vary between 0.3 ns to 11 ns and between 0.3 ns to 6.4 ns for Vertical-Vertical (V-V) and Vertical-Horizontal (V-H) Polarizations, correspondingly.
