Channel measurements in harsh RF propagation environments for over-the-air performance evaluation of wireless devices

Abstract

This paper presents the channel measurements in harsh RF propagation environments using frequency-domain measurement method. A vector network analyzer was used to measure the channel transfer functions in the frequency band of 1-18 GHz. The corresponding channel impulse responses were calculated by taking inverse Fourier transforms of the recorded channel transfer functions. We also presented one of our measurement experiments using this system in a hot-rolled workshop of steel plant. The results include some line of sight (LOS) and non-LOS (NLOS) conditions. The aim here is to collect the necessary data to develop channel models and laboratory-based test and verification methods for the deployment of wireless device.
