Observations on Large-Scale Attenuation Effects in a 26 GHz Urban Micro-Cell Environment Ramírez Arroyo, Alejandro B. Sørensen, Troels Beltoft, Peter Christiansen, Henrik Valenzuela Valdes, Juan Francisco Mogensen, Preben Measurement campaign Outdoor Path gain This letter presents a measurement campaign carried out in an FR2 urban outdoor environment in a live experimental network deployment. The radio propagation analysis from a physical perspective at 26 GHz is essential for the correct deployment and dimensioning of future communication networks. This study performs a walk test emulating realistic conditions under which a pedestrian may be affected, summarizing and evaluating some of the typical effects encountered in a communications scenario such as penetration losses in a building, losses due to vegetation or the human body, or diffraction/scattering propagation around corners in street canyon-like environments. The operational conditions of the 5G network, the urban microcell scenario, and the use of omnidirectional antennas on the UE side validate the channel conditions from a perspective closer to a realistic scenario for a pedestrian within a FR2 live network. 2024-09-26T06:55:44Z 2024-09-26T06:55:44Z 2024-07-26 journal article Ramírez Arroyo, A. et. al.
