TL;DR: Experimental results of the FSO system capable of offering stable performance in terms of measured bit-error-rate (BER) showing error free transmission at 2.5 Gbps over extended period of time and improved fiber received power are presented.

TL;DR: The design concept and performance evaluation results of a newly developed DWDM Radio over Free-Space Optics (RoFSO) system capable of transmitting multiple wireless service signals simultaneously and can provide a stable connection for wireless services are presented.

TL;DR: A data collection framework for disaster mitigation and rescue operation is proposed and the performance of the protocol is compared with that of SENDROM system protocol, where the proposed protocol outperforms the SENDRom protocol.

TL;DR: In this paper, the authors consider how FSOLs act as useful transport media, focusing on practical experience in mobile backhaul networks and refer to studies on FSOL conducted by the International Telecommunications Union (ITU) from the viewpoint of the possible exploitation of the frequency bands above 3,000 GHz, which are outside the scope of the current Radio Regulations.

TL;DR: This work investigates the suitability of utilizing soft-computing (SC) based tools for improving performance of free-space optical (FSO) communications systems and proposes a proposed multi-layer neural network predictor (MNNP) used to predict future parameter values.
