According to Wikipedia: Li-Fi (ˈlaɪfaɪ; short for light fidelity) is wireless communication technology, which utilizes light to transmit data and position between devices.
In technical terms, Li-Fi is a light communication system (hence based on photonics) that is capable of transmitting data at high speeds over the visible light, ultraviolet, and infrared spectrums. In its present state, only LED lamps can be used for the transmission of visible light.
In terms of its end use, the technology is similar to Wi-Fi – the key technical difference being that Wi-Fi uses radio frequency to transmit data.

The new G.9991 Recommendation (“High-speed indoor visible light communication transceiver – System architecture, physical layer and data link layer specification”) recently published by ITU-T is a major step in the wide adoption of LiFi technology in different applications from home/enterprise networking to IoT.
This new Recommendation describes a low-latency, high speed communication system specifically designed to overcome the challenges of LiFi. With the publication of the Recommendation several ASIC implementations are now available leading to the first LiFi mature commercial products.

In today’s World, the most important element of success for any business, industry or even person’s life is to be connected and have realtime access to the constant stream of data being generated by the environment, devices and processes that we interact with. This means that our World becomes data-driven to enrich our decisions and planning, and give us more control over our lives.
The implementation of data-driven World through IoT/IIoT solutions has some connectivity challenges when it comes to reliable bidirectional communication, security, safety, energy consumption, bandwidth, operability, adoption, and standardization. To overcome some of these challenges, RF has started to transit from cm-wave to mm-wave known as 5th generation of RF wireless communication, or 5G. Despite of this development, due to characteristics of radio frequency, there are still several shortcomings that need to be addressed to make the connected World concept comes true.

Today’s Internet of Things (IoT), covering any communication between devices, is narrowband and not always provides reliability and low latency at the same time. A wide range of future IoT applications, i.e. flexible manufacturing, augmented reality and autonomous cars, will use artificial intelligence in the cloud to process sensor data jointly in real time.
This future IoT will need mobile communication providing high bandwidth, reliable connectivity and low latency at the same time. While radio spectrum is densely populated, light communication (LC) can use unlicensed optical spectrum and enable high data rates over short distances for future IoT. By networking multiple LC-enabled access points, also known as Li-Fi, one can build a new mobile communication system integrated with lighting infrastructure that enables the future IoT.

The Internet of Things (IoT) presents a wide range of implementation challenges, including ensuring security, lowering energy consumption, and providing reliable communications. Optical Wireless Communications (OWC) and LiFi can assist in achieving this, and provide secure contained communications channels, energy that can be harvested by IoT nodes, and critically; new regions of the electromagnetic spectrum to alleviate the demands on the congested RF spectrum.

In this information age, communication is central to our societies but it is taking a toll on the earth. As reported by Time Magazine, by 2013, we were already using 50% more energy moving bytes than moving airplanes around the world. Our societies face a major challenge: How can we satisfy our ever-growing demand for communication but in a sustainable manner?
Any new technology we develop must leave no ecological footprint, or as Bill Gates puts it “we need to go all the way down to zero”. We are investigating a new wireless communication system that relies on a free, abundant and natural resource: sunlight. Our concept operates in a way similar to using a mirror to send morse codes via reflections. We cover objects with smart materials to obtain similar changes in reflections, but without you noticing them.

The evolution of the Internet of Things will not only dramatically increase the number of connected devices, but will also leverage light communications to further increase the density of connected nodes, to enable ultra-reliable low latency communication, and to avoid electromagnetic compatibility and interference issues of radio signals.
Aside of the efficiency of the physical layer, there are extended requirements to the medium access control (MAC) layer functions of Li-Fi to meet the operational dynamics of IoT applications and the constraints of tiny communication nodes.
