LIDAR-Assisted Channel Modelling for LiFi
Optical Fiber Communication Conference (OFC) 2022, 2022We present fast and accurate modelling of LiFi channels using data from LIDAR scans. Line-of-sight, first and residual reflections are modelled in the frequency-domain and using the integrating-sphere method. Model and measurement show good agreement.

Spatial Channel Hardening For LiFi Networks
2020 IEEE Globecom Workshops (GC Wkshps, 2020Intrinsically, Light Fidelity (LiFi) networks are robust in both time and frequency domains. However, in the spatial domain LiFi channels vary significantly because light-emitting diode (LED) light is spatially confined to a small area. This degrades spatial robustness of LiFi networks.

Access point assignment in hybrid LiFi and WiFi networks in consideration of LiFi channel blockage
2017 IEEE 18th International Workshop on Signal Processing Advances in Wireless Communications (SPAWC), 2017As a promising complement to the increasingly congested wireless fidelity (WiFi) system, light fidelity (LiFi) has recently drawn massive attention due to the wide and unregulated visible light spectrum. Also, the light waves cannot penetrate walls which enables interference avoidance between compartments.

Resource Allocation in LiFi OFDMA Systems
GLOBECOM 2017 - 2017 IEEE Global Communications Conference, 2017Light Fidelity (LiFi) is a recently proposed technology that combines illumination and high speed wireless communication using light emitting diodes (LEDs). Unlike radio frequency (RF) channels, LiFi channels do not exhibit fading characteristics as the detector size is much larger than the wavelength.

In recent years, fibre-reinforced polymeric composites have received attention because of their high specific strength and modulus. Although, generally high strength synthetic fibres are used in the composites, there has been a growing interest in the use of natural cellulosic fibres as the reinforcement for polymeric matrix. While these fibres may not

LiFi Communication – An Introduction
2022Light Fidelity (LiFi) is a part of Visible Light Communication (VLC) technology developed to overcome the rate speeds of current conventional wireless communication methods, i.e., WiFi. This paper focuses on the basic working of a communication device using light as a medium.

Lifi- Light Fidelity Technology
2017 International Conference on Current Trends in Computer, Electrical, Electronics and Communication (CTCEEC), 2017Li-Fi technology means Light Fidelity technology which was proposed by Harald Haas (a German Physicist). As the name suggests Li-Fi is a data transmission technique which uses illumination for sending the data or light as a medium of communication. It transmits data with the help of an LED bulb having variation in its intensity which has a speed of ...
