Atmospheric Attenuation and Scintillation Effects on the Range of EDM Instruments

Garrido-Villén, Natalia; Antón Merino, Alberto; Berné Valero, José Luis; Mata, Rafael; Raboso García-Baquero, David (American Society of Civil Engineers, 2015-08)

This investigation aimed to study the range of various electronic distance measurement (EDM) instruments used in survey engineering, assuming different weather conditions and different terrain altitudes, by controlling ...
Combined effect of turbulence and aerosol on free-space optical links

Libich, Jiri; Perez, Joaquin; Zvanovec, Stanislav; Ghassemlooy, Zabih; Nebuloni, Roberto; Capsoni, Carlo (The Optical Society, 2017-01-10)

[EN] Despite the benefits of free-space optical (FSO) communications, their full utilization is limited by the influence of atmospheric weather conditions, such as fog, turbulence, smoke, snow, etc. In urban environments, ...
Indoor free space optics link under the weak turbulence regime: measurements and model validation

Pernice, Riccardo; Ando, Andrea; Cardinale, Marzia; Curcio, Luciano; Stivala, Salvatore; Parisi, Antonino; Busacca, Alessandro C.; Ghassemlooy, Z.; Perez, Joaquin (Institution of Engineering and Technology (IET), 2015-01-02)

In this study, the authors present the measurements performed on a free space optics (FSO) communications link using an indoor atmospheric chamber. In particular, the authors have generated several different optical ...
The effect of buildings on atmospheric turbulence in open spaces in Western São Paulo State, Brazil

Machado, Antonio (Editorial Universitat Politècnica de València, 2018-04-20)

[EN] This paper seeks to identify a pattern of air turbulence that reflects the effect of buildings on air turbulence characteristics measured in open spaces in Western São Paulo State, Brazil. Atmospheric turbulence was ...
Wideband QAM-over-SMF/turbulent FSO downlinks in a PON architecture for ubiquitous connectivity

Nguyen, Dong-Nhat; Vallejo-Castro, Luis; Bohata, Jan; Ortega Tamarit, Beatriz; Ghassemlooy, Zabih; Zvanovec, Stanislav (Elsevier, 2020-11-15)

[EN] We propose and investigate for the first time a seamless millimeter-wave (mmW) radio-over-fiber (RoF) and radio-over-free-space optics (FSO)-based downlink for use in a passive optical network architecture using 4-, ...
