Visible-light communications and light fidelity

open access: yes, 2020
This chapter starts by explaining the significantly increased interest in visible-light communications (VLC) and light fidelity (LiFi) during the last 10 years. Next, a taxonomy of the various optical wireless communications technologies is provided, and we discuss their key discriminating features.

Li-Fi: Light fidelity-a survey

Wireless Networks, 2015
Visible light communication (VLC), which uses a vast unregulated and free light spectrum, has emerged to be a viable solution to overcome the spectrum crisis of radio frequency. Light fidelity (Li-Fi) is an optical networked communication in the subset of VLC to offload the mobile data traffics which offers many advantages at indoor scenario.

Survey on Light-Fidelity

2018 International Conference on Smart Systems and Inventive Technology (ICSSIT), 2018
In the present era, Wi-Fi is the most useful wireless communication. It works on the basis of the radio wave spectrum. Radio waves are very harmful. To overcome these and to increase bandwidth, efficiency, and speed, a new technology LI-FI is developing. LI-FI stands for light fidelity.

Light-Fidelity Systems: Architecture and Modulation

open access: yes, 2023
New technologies such as Wireless Fidelity now make wireless Internet access possible. Wi-Fi, also known as IEEE 802.11, uses WLAN -11n to transmit broadband data over a 150 Mbps range. A more robust wireless access technology was needed to address themany issues of security, transmission capacity, throughput, and interference.
