Investigation of Underground Communication Quality Using Distributed Antenna Systems Considering Radio-Frequency Signal Propagation Characteristics in Almaty Metro Tunnels

This study investigates radio-frequency signal propagation in underground metro tunnels with a focus on distributed antenna system (DAS) deployment. Deterministic simulations were performed using Altair WinProp 2024.1 (ProMan) with a 3D ray-tracing engine (GO + UTD) at 2.4 GHz in a reinforced concre...
