G.hn backbone and ecosystem support for Li-Fi use cases. Standardization, Spectrum and Security

G.hn

ITU-T standard based G.hn technology augments spectrum usage and provides security enhancements that special use cases need. For schools, hospitals, airports, defense and government buildings and other cases where sensitive information can be a target of cyberattack, Li-Fi eliminates the risk of data interception by outsiders which are out of sight, therefore offering a vastly enhanced security platform which can be ensured using G.hn as reliable backbone.

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.

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”

ITU-T G.9991, the new LiFi standard ready for product deployment

Marcos Martinez

by Marcos Martinez, MaxLinear Inc

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.

This presentation briefly describes the main characteristics and advantages of the new Recommendation and introduces an example of G.9991 implementation.

About Marcos Martinez

Marcos Martínez received an M.S. degree in telecommunications engineering from the Polytechnic University of Valencia (Spain). He worked for Alcatel Microelectronics, DS2 and Marvell Semiconductors in the design of high performance embedded systems in automotive, DSL, Optical access and powerline, focusing on R&D activities. In 2017, he joined MaxLinear Inc where he has been leading the standardization activities related to wireline networking and has participated in different standardization groups working on wireline networking (ITU-T Q18/15, BBF, HomeGrid Forum and Gigawire Alliance). Recently, he has been a key contributor to ITU-T G.9991 Recommendation on LiFi transceivers.

About MaxLinear Inc

MaxLinear delivers high-performance broadband and networking semiconductors based on its highly integrated radio frequency analog technology, high-performance optical networking technology and its pioneering MoCA and Direct Broadcast Satellite ODU single-wire technology.

MaxLinear was founded in 2003. The company’s original high performance, radio-frequency receiver products capture and process digital and analog broadband signals for applications including terrestrial, cable and satellite television and DOCSIS broadband. These products include both RF receivers and RF receiver systems-on-chip, or SoCs, which incorporate highly integrated radio system architecture and demodulator technology. The company’s products were based on its pioneering low power, low cost CMOS process technology.

In 2015, the company acquired Entropic, the world leader in semiconductor solutions for the connected home. Entropic pioneered multimedia over coax (MoCA) home networking technology. The company’s technology transforms how traditional broadcast and IP streaming video is seamlessly, reliably, and securely delivered, processed, and distributed into and throughout the home.

MaxLinear also offers optical networking driver and trans-impedance amplifier ICs for 100G / 400G optical data center networks. The devices use advanced technology that cut in half the number of channels needed in optical transmission modules, reducing power consumption, size and cost for 100Gbps and 400Gbps networks.

MaxLinear technology is trusted by leading telephone, cable and satellite operators, set-top box manufacturers, networking equipment providers and consumer technology providers.
