LiFi is mobile communications by using the light. LiFi can be used next to Wi-Fi and 5G, so that radio provides ubiquitous coverage and light adds unlimited capacity. This talk will focus on LiFi for Industry 4.0. LiFi is deployed at the ceiling as a dense grid of wireless access points with a few meters of distance. For Industry 4.0, LiFi is operated as a large, distributed multiple-input multiple-output system.Continue reading “LiFi for Industry 4.0”

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.
