At Techopedia, we aim to provide insight and inspiration to IT professionals, technology decision-makers and anyone else who is proud to be called a geek. From defining complex tech jargon in our dictionary, to exploring the latest trend in our articles or providing in-depth coverage of a topic in our tutorials, our goal is to help you better understand technology - and, we hope, make better decisions as a result.

This technology uses a part of the electromagnetic spectrum that is still not greatly utilized- The Visible Spectrum. Light is in fact very much part of our lives for millions and millions of years and does not have any major ill effect. Moreover there is 10,000 times more space available in this spectrum and just counting on the bulbs in use, it also multiplies to 10,000 times more availability as an infrastructure, globally.

The inherent security advantages of using light for wireless communications allow companies to enhance security for their wireless networks significantly. The ability to strictly define the communication area of a LiFi access point allows precise partitioning of the office environment. In addition, the technology requires proprietary hardware before anyone can access the system.

Due to the high-speed, low latency characteristics of LiFi and the ubiquitous nature of LED lights in our transport infrastructure. LiFi is an ideal technology to complement and augment current wireless technologies used for Autonomous transport and cars.

Li-Fi (also written as LiFi) is a wireless communication technology which utilizes light to transmit data and position between devices. The term was first introduced by Harald Haas during a 2011 TEDGlobal talk in Edinburgh.[1]

Li-Fi is a derivative of optical wireless communications (OWC) technology, which uses light from light-emitting diodes (LEDs) as a medium to deliver network, mobile, high-speed communication in a similar manner to Wi-Fi.[6] The Li-Fi market was projected to have a compound annual growth rate of 82% from 2013 to 2018 and to be worth over $6 billion per year by 2018.[7] However, the market has not developed as such and Li-Fi remains with a niche market.[8]

Although Li-Fi LEDs would have to be kept on to transmit data, they could be dimmed to below human visibility while still emitting enough light to carry data.[19] This is also a major bottleneck of the technology when based on the visible spectrum, as it is restricted to the illumination purpose and not ideally adjusted to a mobile communication purpose, given that other sources of light, for example the sun, will interfere with the signal.[21]

Since Li-Fi's short wave range is unable to penetrate walls, transmitters would need to installed in every room of a building to ensure even Li-Fi distribution. The high installation costs associated with this requirement to achieve a level of practicality of the technology is one of the potential downsides.[7][9][22]

VLC technology was exhibited in 2012 using Li-Fi.[27] By August 2013, data rates of about 1.6 Gbit/s were demonstrated over a single color LED.[28] In September 2013, a press release said that Li-Fi, or VLC systems in general, do not absolutely require line-of-sight conditions.[29] In October 2013, it was reported Chinese manufacturers were working on Li-Fi development kits.[30]

Many experts foresee a movement towards Li-Fi in homes because it has the potential for faster speeds and its security benefits with how the technology works. Because the light sends the data, the network can be contained in a single physical room or building reducing the possibility of a remote network attack. Though this has more implications in enterprise and other sectors, home usage may be pushed forward with the rise of home automation that requires large volumes of data to be transferred through the local network.[40]

Li Fi Tech News is a media news platform covering articles, photos, videos and news about Li Fi, the next level and revolution in wireless communications. Li Fi Tech News mission is to enlighten individuals and bring awareness of the mechanism, potential, applications and benefits of this wireless communication technology called Li-Fi

LiFi technology is considered safer and greener compared to the existing modes of WiFi communication, telecom tower-based communication or LAN network. Due to the risk involved with radio-magnetic waves through the existing technologies, they are often not used in critical areas or ICUs. No WiFi or mobile phones are allowed near Covid-19 patients, thereby making remote monitoring of the patients almost impossible.

Li-Fi (Light Fidelity) is similar to Wi-Fi (Wireless Fidelity) but uses light for data transmission instead of radio waves. It facilitates the wireless method of data transmission through Visible Light Communication (VLC) technology and can be up to 100 times faster than Wi-Fi. It uses solid-state lighting (SSL) such as LED bulbs.

4- Availability: With Li-Fi, every light source can facilitate you with the internet. Once the technology is available to the general public, it can be accessed via street lights, building lights, and so forth.

In 2011, Chair of Mobile Communications at the University of Edinburgh, Professor Harald Haas prompted about Li-Fi at TED Global Talk. Professor Haas is considered to be the founder of this technology. In September 2013, his company released the world's first commercially available Li-Fi technology.

Nowadays, a major open issue in most cities is to improve traffic conditions by means of continuous surveillance of drivers. Manual traffic monitoring is a classical approach that is costly and inefficient since a high number of human resources are needed and only some vehicular crossings can be covered at partial times. To tackle this issue, the authors in [1] proposed a fog-based model for driving rule monitoring services. Such systems can easily be installed in traffic lights by means of a LiFi communication system to convey information in a smart city environment, where the traffic light communicates to all vehicles in the queue informing them about their individual average speed or driving infractions that happened in the previous streets, for example. However, the LiFi system is not limited to traffic information, since, as considered in Smart Cities applications [2], different types of information regarding the quality of life and city management can be conveyed to the passing vehicles. Building on this, we propose to use the already implemented infrastructure of light in traffic light and cars to convey this information in an efficient manner (since lights have to be used in vehicular systems), that does not use already crowded radio frequencies and provides a fast and reliable data link between cars using LiFi technology.
