AoA Estimates for LPWAN Technologies: Indoor Experimental Analysis

open access: yes2021 15th European Conference on Antennas and Propagation (EuCAP), 2021
In this paper, we present an experimental analysis of the Angle of Arrival (AoA) estimation accuracy in an indoor environment. We utilized an AoA estimation system that is suitable for Low Power Wide Area Network (LPWAN) technologies. The AoA estimation system constituted 8 antenna elements that are distributed as Uniform Linear Array (ULA) antenna ...
