Path loss model in outdoor environment at 32 GHz for 5G system

Abstract

This paper presents the outcome of outdoor measurement campaigns for 5G system at 32 GHz, which were conducted at the University Technology Malaysia (UTM), Kuala Lumper branch. Featuring measurement results of line-of-sight (LOS) for Co- and Cross antenna polarizations using highly direction horn antennas at transmitter and receiver are investigated for large scale path loss models. For non-line of sight (NLOS) case study, the horn and omni directional antennas are used at the receiver side for comparing horn-horn and horn-omni cases. Based on the measured data, the close-in free space and floating intercept path loss models are investigated for a unique environment. The results show that the path loss exponent range is 3.4–6.7 based on different antenna configuration for LOS and NLOS scenarios. This work founds that the FI path loss model is not suitable for NLOS scenario at such particular environment.
