Observations on Large-Scale Attenuation Effects in a 26 GHz Urban Micro-Cell Environment
Alejandro Ramírez-Arroyo, Troels B. Sørensen, Peter Beltoft +3
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 physica…
FR2 5G Networks for Industrial Scenarios: Experimental Characterization and Beam Management Procedures in Operational Conditions
Alejandro Ramírez-Arroyo, Melisa López, Ignacio Rodríguez +5
Industrial environments constitute a challenge in terms of radio propagation due to the presence of machinery and the mobility of the different agents, especially at mmWave bands.…
Empirical Validation of a Class of Ray-Based Fading Models
Juan E. Galeote-Cazorla, Alejandro Ramírez-Arroyo, F. Javier Lopez-Martinez +1
As new wireless standards are developed, the use of higher operation frequencies comes in hand with new use cases and propagation effects that differ from the well-established stat…
Joint Ultra-wideband Characterization of Azimuth, Elevation and Time of Arrival with Toric Arrays
Alejandro Ramírez-Arroyo, Antonio Alex-Amor, Rubén Medina +2
In this paper, we present an analytical framework for the joint characterization of the 3D direction of arrival (DoA), i.e., azimuth and elevation components, and time of arrival (…
