“…The first solution is suitable for indoor environments, such as houses, companies, industries, and inside vehicles, cars, and airplanes. The use of this method [180] would create many CCI between APs, which may add more challenges when applying the LB algorithm [66,82,79,84,94] HO management [66], and interference management and coordination [117]. The second solution is more suitable for outdoor places, such as fields, open spaces, and streets, to provide a more prominent service area, a wide attocell, and a stronger optical signal that contributes to the optical gain [101].…”

This paper extensively reviews and analyses Light Fidelity (LiFi), a new technology that uses light to transmit data as a high-speed wireless connection system from a wide spectrum of domains. An in-depth analysis and classifications of pertinent research areas for LiFi networks are presented in this paper. The various aspects constituting this paper include a detailed literature review, proposed classifications, and statistics, which further is deliberated to encompass applications, system architecture, system components, advantages, and disadvantages. LiFi and other technologies are compared, multi-user access techniques used in LiFi networks are investigated and open issues are addressed in detail. The paper is concluded with a comprehensive taxonomy of literature comparison that has served as the basis of the proposed open issues and research trends.

Wireless communications refer to data transmissions in unguided propagation media through the use of wireless carriers such as radio frequency (RF) and visible light (VL) waves. The rising demand for high data rates, especially, in indoor scenarios, overloads conventional RF technologies. Therefore, technologies such as millimeter waves (mmWave) and cognitive radios have been adopted as possible solutions to overcome the spectrum scarcity and capacity limitations of the conventional RF systems. In parallel, visible light communication (VLC) has been proposed as an alternative solution, where a light source is used for both illumination and data transmission. In comparison to RF links, VLC links present a very high bandwidth that allows much higher data rates. VLC exhibits also immunity to interference from electromagnetic sources, has unlicensed channels, is a very low power consumption system, and has no health hazard. VLC is appealing for a wide range of applications including reliable communications with low latency such as vehicle safety communication. Despite the major advantages of VLC technology and a variety of its applications, its use has been hampered by its cons such as its dependence on a line of sight connectivity. Recently, hybrid RF/VLC systems were proposed to take advantage of the high capacity of VLC links and better connectivity of RF links. Thus, hybrid RF/VLC systems are envisioned as a key enabler to improve the user rates and mobility on the one hand and to optimize the capacity, interference and power consumption of the overall network on the other hand. This paper seeks to provide a detailed survey of hybrid RF/VLC systems. This paper represents an overview of the current developments in the hybrid RF/VLC systems, their benefits and limitations for both newcomers and expert researchers. INDEX TERMS Radio frequency (RF), visible light communication (VLC), hybrid RF/VLC, wireless fidelity (Wi-Fi), hybrid networks, hybrid RF/VLC environments.

Light Fidelity (Li-Fi) is a technology in the field of Visible Light Communications (VLC) that renders transmission of data via illumination by sending data through a Light Emitting Diode (LED) light bulb. This technology uses a photo-detector to receive light signals and a signal processing element to change over the information into a stream-capable substance. Out of this survey paper, we see that Li-Fi technology execution and research has been carried out in patient monitoring systems, vehicle toll gate systems, under roof blind navigation systems and other applications. Limited research has been carried out on Li-Fi communication networks and deployment. Nonetheless, there is a lot of potential to implement it. This includes many applications in sensitive electromagnetic interference environments such as air crafts and power plants where Wireless Fidelity (Wi-Fi) is not suitable but fast and interconnected data systems are still required. Li-Fi has potential in areas where secure networks are required and where there is need to track signal availability and transmission radius as in banks and intelligence gatherings like in the military and government special operations. It can also provide high data capacity in heavily populated environments such as colleges, malls and conference centers. There are still unattended scopes like Li-Fi network integration with the mobile network and the optical fiber network. No guidelines have been developed for the efficient deployment of Li-Fi networks to suit different applications such as hospitals, clinics and banks.
