Field report on experimental comparison of a WiFi mesh network against commercial 5G in an underground disaster environment. Bravo-Arrabal, Juan Álvarez-Merino, Carlos Simón Fernández-Lozano, Juan Jesús Gómez-Ruiz, José Antonio Mandow, Anthony Barco-Moreno, Raquel García-Cerezo, Alfonso José Robots autónomos Operaciones de salvamento y rescate Mobile robots in disaster scenarios such as tunnels, mines, or collapsed structures face communication challenges for reliable video streaming to remote control centers. Commercial fifth-generation (5G) networks provide low latency and high bandwidth, especially in urban areas, but ad hoc WiFi networks with static and robotic nodes can provide a solution to attenuation in occluded areas. This paper offers a field experiment report from a search and rescue (SAR) exercise where we tested a WiFi mesh network against commercial 5G in tunnels 184 m long, 6 m wide, and 4 m high. Two operator streamed video to the Internet through a mesh that consisted of two static nodes and two mobile nodes on unmanned ground vehicles (UGV). Latency was measured for both operators for different video resolutions, as well as for a 5G customer-premises equipment (CPE) on-board a scout-UGV. The paper discusses experimental results and lessons learned. 2024-03-04T11:34:40Z 2024-03-04T11:34:40Z 2023-11 conference output Juan Bravo-Arrabal, C.S. Álvarez-Merino, J.J.
