A Survey of Underwater Optical Wireless Communications

IEEE Communications Surveys and Tutorials, 2017
Underwater wireless communications refer to data transmission in unguided water environment through wireless carriers, i.e., radio-frequency (RF) wave, acoustic wave, and optical wave. In comparison to RF and acoustic counterparts, underwater optical wireless communication (UOWC) can provide a much higher transmission bandwidth and much higher data ...

Capacity of wireless optical communications

IEEE Journal on Selected Areas in Communications, 2003
We consider the ergodic capacity and capacity-versus-outage probability of direct-detection optical communication through a turbulent atmosphere using multiple transmit and receive apertures. We assume shot-noise-limited operation in which detector outputs are doubly stochastic Poisson processes whose rates are proportional to the sum of the ...

Wireless optical communications: a survey

2004 IEEE Wireless Communications and Networking Conference (IEEE Cat. No.04TH8733), 2004
The demand for wireless broadband communications has been growing steadily for last several years. The congestion and the limitations on bandwidths of the radio spectrum have inhibited unrestricted growth of radio wireless systems. Wireless optical, however, holds the promise of delivering data rates that can meet the broadband requirements.

Guest editorial: optical wireless communications

IEEE Journal on Selected Areas in Communications, 2009
Optical wireless communication (OWC) systems provide many advantages over radio frequency (RF) wireless technologies in some scenarios, including significantly higher data rates and a large amount of available license-free frequency spectrum. Recently, OWC has also been proposed in fifth generation 5G standard as a tool to augment capacity due to RF ...

Optical Wireless Communication

Proceedings of the 24th Annual International Conference on Mobile Computing and Networking, 2018
Data is the new currency impacting everybody's lives. As the modern world receives & sends millions of Terabytes of data every day, the present-day wireless data communication technologies comprising of Wi-Fi & 4G-LTE is on the verge of becoming partially inept for information exchange as they suffer from spectrum congestion in both controlled and ...
