UAV Corridor Coverage Analysis with Base Station Antenna Uptilt and Strongest Signal Association

no code implementations27 Mar 2024 Sung Joon Maeng, İsmail Güvenç

In this paper, we address this limitation by considering the strongest BS signal association in UAV corridors, which enables enhanced coverage within the corridor compared to the nearest BS association.

Impact of 3D Antenna Radiation Pattern in UAV Air-to-Ground Path Loss Modeling and RSRP-based Localization in Rural Area

no code implementations24 Jul 2023 Sung Joon Maeng, Hyeokjun Kwon, Ozgur Ozdemir, İsmail Güvenç

By analyzing reference signal received power (RSRP) using path loss models that account for antenna patterns, we observed that our measurement results, obtained at different UAV heights, aligned well with the two-ray path loss model when incorporating the measured antenna pattern.

Kriging-Based 3-D Spectrum Awareness for Radio Dynamic Zones Using Aerial Spectrum Sensors

no code implementations12 Jul 2023 Sung Joon Maeng, Ozgur Ozdemir, Ismail Guvenc, Mihail L. Sichitiu

In particular, we introduce a 3D Kriging interpolation technique that uses realistic 3D correlation models of the signal power extracted from extensive measurements carried out at the NSF AERPAW platform.

RF SSSL by an Autonomous UAV with Two-Ray Channel Model and Dipole Antenna Patterns
