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

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.

Interview

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.

“Special quote”
“Light communications is not only a new technology but will change the involved industries”
