Channel Knowledge Maps for FR3 UAV Base Stations: Dataset and ML-based Modeling
Guillem Moreno~Garcia, Sergi Abadal, Evgenii Vinogradov
This paper introduces a dense upper mid-band Frequency Range (FR3) Channel Knowledge Map (CKM) dataset for Uncrewed Aerial Vehicles (UAVs) with an on-board base station (UxNB). It…
UPSim: UxNB Propagation Simulator for 3D Map-Driven FR3 Deployments
Evgenii Vinogradov
We introduce UPSim (UxNB Propagation Simulator), an open-source, Ray Tracing-calibrated solution for spatially consistent FR3 (16.95 GHz) air-to-ground propagation modeling in Uncr…
Communication Technologies for Intelligent Transportation Systems: From Railways to UAVs and Beyond
Shrief Rizkalla, Adrian Kliks, Nila Bagheri +25
This white paper aims to comprehensively analyze and consolidate the state of the art in communication technologies supporting modern and future Information and Communication Techn…
Spatially Consistent Air-to-Ground Channel Modeling and Simulation via 3D Shadow Projections
Evgenii Vinogradov, Aymen Fakhreddine, Abdul Saboor +2
We present an approach for spatially-consistent semi-deterministic Air-to-Ground (A2G) channel modeling in Unmanned Aerial Vehicle-assisted networks. We use efficient 3D building s…
Millimeter-Wave UAV Channel Model with Height-Dependent Path Loss and Shadowing in Urban Scenarios
Abdul Saboor, Evgenii Vinogradov
Uncrewed Aerial Vehicles (UAVs) serving as Aerial Base Stations (ABSs) are expected to extend 6G millimeter-Wave (mmWave) coverage and improve link reliability in urban areas. Howe…
Trajectory-Aware Air-to-Ground Channel Characterization for Low-Altitude UAVs Using MaMIMO Measurements
Abdul Saboor, Zhuangzhuang Cui, Achiel Colpaert +3
This paper presents a comprehensive measurement-based trajectory-aware characterization of low-altitude Air-to-Ground (A2G) channels in a suburban environment. A 64-element Massive…
CASH: Context-Aware Smart Handover for Reliable UAV Connectivity on Aerial Corridors
Abdul Saboor, Zhuangzhuang Cui, Achiel Colpaert +2
Urban Air Mobility (UAM) envisions aerial corridors for Unmanned Aerial Vehicles (UAVs) to reduce ground traffic congestion by supporting 3D mobility, such as air taxis. A key chal…
Spatially Consistent Air-to-Ground Channel Modeling with Probabilistic LOS/NLOS Segmentation
Evgenii Vinogradov, Abdul Saboor, Zhuangzhuang Cui +1
In this paper, we present a spatially consistent A2G channel model based on probabilistic LOS/NLOS segmentation to parameterize the deterministic path loss and stochastic shadow fa…
