What is Li-Fi?

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.

Enabling Li-Fi for the Internet of Things: advanced MAC layer aspects

Maximilian Riegel

by Maximilian Riegel, Nokia

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.

The presentation shows the interaction of the Li-Fi MAC layer within an end-to-end IoT application architecture and provides an overview of desired MAC functions for IoT deployments. Related to current Li-Fi standardization activities, the applicability and deficiencies of the IEEE 802.11 MAC for Li-Fi based IoT applications are evaluated in the conclusion.


What drives you?
The potential that Li-Fi could extend wireless communications into new application domains.

Why should the delegate attend your presentation?
The presentation provides new insights into the relation and interdependence of the MAC layer functions with end-to-end communications.

What emerging technologies/trends do you see as having the greatest potential in the short and long run?
Virtualization of everything will lead to a heavily growing demand for better and more communication links.

What kind of impact do you expect them to have?
With need for communication links everywhere, communication will become integral part of infrastructures, e.g. merging together lighting with communications.

What are the barriers that might stand in the way?
Integration of communications into infrastructures demands much better cooperation between different industries than available today.

Enhance Lighting for the Internet of Things

volker jungnickel

by Volker Jungnickel, Fraunhofer Heinrich Hertz Institute

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 main challenge to approach future IoT is to develop Li-Fi further into the mass-market serving a greater variety of use cases than today. Therefore, Li-Fi needs an open architecture, consensus building towards standards, a roadmap to support future IoT and technology demonstrations in real environments, such as indoors, manufacturing, logistics, conference rooms and outdoors for fixed-wireless access.

The talk will introduce ideas and solutions developed in the Horizon2020 ICT project Enhance Lighting for the Internet of Things (ELIOT) funded by the European Union. ELIOT is the first industry-driven large-scale innovation action on Li-Fi. ELIOT will focus on challenges and solutions paving the way from research to real-world scenarios and promising applications.


What drives you?
To make LiFi a commercial reality.

Why should the delegate attend your presentation?
To get introduced into a new application for LiFi.

What emerging technologies/trends do you see as having the greatest potential in the short and long run?
5G integrated with mm-wave, WiFi and LiFi.

What kind of impact do you expect them to have?
Closing the gaps in wireless access techniques in order to address the needs of new application domains like URLLC and IoT.

What are the barriers that might stand in the way?
Experts from communications, lighting and photonic components need to focus on a new technology, agree on one standard for baseband processing, more trials in real application scenarios.
