A High Altitude Platform Station (HAPS) is a network node that operates in the stratosphere
at an of altitude around 20 km and is instrumental for providing communication services …

A new generation of mobile communications has been evolving for every 10 years, keeping
in mind the enormous data traffic, huge capacity requirements, excellent quality of service …

This paper studies the performance of mixed millimeter-wave radio-frequency (mmWave
RF), free-space optics (FSO) systems in a highly scalable and cost-effective solution for fifth …

In this paper, we propose a switching scheme for a hybrid free-space optical (FSO)/radio
frequency (RF) system with a selective decode-and-forward (DF) relay network. Specifically …

In this paper, a 200-Gb/s free-space optical (FSO) wavelength division multiplexing (WDM)
transmission architecture based on multiwavelength directly modulated transmitter optical …

This paper provides a performance analysis of a simultaneous free-space-optics (FSO) and
millimeter wave (mmWave) communication system with selection-combining and maximal …

We propose and experimentally demonstrate, for the first time, a system which integrates
millimeter-wave (MMW) and free-space-optics (FSO) analog radio-over-fiber (A-RoF) …

This paper proposes a novel design and analyzes security performance of quantum key
distribution (QKD) protocol over free-space optics (FSO). Unlike conventional QKD protocols …

The rapid involution of the mobile generation with incipient data networking capabilities and
utilization has exponentially increased the data traffic volumes. Such traffic drains various …

The propagation of millimeter (MMW) and submillimeter (terahertz, THz) waves in the
atmosphere is subject to absorptive and dispersive effects. The resulting attenuation and …
