Li-Fi Conference 2022 – LiFi Tech News Recap Series Part 1 - The Light Communication Alliance (LCA)
Li-Fi Conference 2022 - The LCA
The first speaker of the Li-Fi Conference 2022 was the chairman of the Light Communications Alliance (LCA), Marc Fleschen. He is the founder of Zero1 company specialising in optical camera communication. Winner of the French tech startup awards 2017, start-up of the Year 2018 by CCI French tech international, Prix du Jury 2018 UAE French embassy.
Marc Fleschen discussed the following topics during his presentation:
History of the Light Communication Alliance, LCA in a nutshell, LCA members, LCA ecosystem, Light Communication technologies, Strong added values, Who is asking for this technology?, Standardization status, Some use cases and examples of products deployed.
Below are some of the statements from the presentation:
“And so, we will explain the overall purpose of the LCA, its mission and the organisation around the ecosystem. The first thing that we believe was a catalyst to the expansion of light communication overall was also at the very beginning of the expansion for LEDs that as you can see on the market penetration is going.”
“The LCA was kicked off in 2017, where the first meeting happened during one LiFi meeting. The members decided to actually gather and create what is known as today the Light Communication Alliance. Following that, we had many work sessions amongst all the different members in order to be able to create this picture on the colour of the light communication, Ryan's to buy Lowe's, then, in 2019, the assemble actually just a little bit before the world changed, as we knew it. And we officially launched and registered in Luxembourg, the Light Communications Alliance as a nonprofit organisation, which is fully operational now for more than two years and is welcoming new members, of course, and has been operating for the last two years to be able to deliver a different type of mission.”
“The motivation around the light communication alliance is obviously to gather an ecosystem, the ecosystem, as you can see, the member on the right of the slide is growing and this ecosystem is today present in innovation or prison online with most of the people around this life by contract once. And it's really exciting to see this ecosystem growing. And the reason why and our motivation is to actually support that ecosystem and to support the growth of each of you individually, each of the companies that are the solution use cases in commercial purpose and implementation as well. The ecosystem is very wide.”
“Our mission was to organise also several different use cases. Taxonomy was one of the first tasks that we organised in order to be able to deliver the right message about what light communication is, and what are the different technologies that use light communications.”
“In the Alliance, we work with the taxonomy of actually two technologies that we're focusing on free space of cheek is a non-technology that has been here for many years, but it's using light, we actually defence about it, but we are not focusing on that technology, the tooth energy or wherever. And we're working on our optical, chemical communications and lifi.”
“The distinction between both technologies is really paramount because for many, many years, the message was a little bit blurred. And the problem about a blurred message is that it creates confusion amongst professionals, those professionals could actually be silicon vendors, mobile manufacturers, but also telecom operators.”
“Actually, we are complementary of every other technology, we are really complementary to Wi-Fi, we actually work alongside that Wi-Fi technology, we actually operate where Wi-Fi is not appropriate or is not working, for example, where there is a combinatoric perturbation, but the purpose of the alliance is to actually complement the line of different layers of communication, including Wi-Fi technology. And that's why we do work along the Wi-Fi technology and also different alliances that work with Wi-Fi.
“We are also within the light communication standardisation workshop and the people in charge of that. And there are currently two standards that are being followed, I would say by the light communication lines and by its members, one being the ITU and the other one being the IEEE.”
”We do work on different market adoptions and we have a timeline with his what we do in the light communications, we try to support this communication adoption, we try to have messages for that we do deliver white paper, we work on new white paper, we participate to several different events. And we are honoured and proud to join with Jakajima for this lifi conference because we believe it's very important to be able to spread the word outside about what is happening in light communication because for many years, the message was unclear.”
“We have different members. Now we have United States members, but we also have Korean, and Japanese members. And we are very happy that the lie communication alliance is as of today, one of the largest, if not the largest, gathering ecosystem, around vendors, operators, members and participants of the Alliance.”
”Once again, it's very important to understand that this lifi conference and today's experiment for each of you, as a huge implication on understanding that light communication is not laboratory. It's not in the study. It's commercial. It's now it's available. And with all the increase of the needs of technological support for AR VR, what 5g is delivering undergrowth to the whole to CG light communication is definitely Netmums to help bring a new layer of communication that has a sustainable, long-term evolution. And this is what as the light communication wants to.”

What is LiFi?
LiFi, also known as "Light Fidelity" is a wireless optical networking technology, which uses light-emitting diodes (LEDs) to transmit data. In 2011, professor Harald Haas made a LiFi demonstration at the TED (Technology, Entertainment, Design) Global Talk on Visible Light Communication (VLC).
VLC uses light as a medium to deliver high-speed communication like Wi-Fi and complies with the IEEE standard IEEE 802.15.7. The IEEE 802.15.7 is a high-speed, bidirectional, and fully networked wireless communication technology-based standard similar to Wi-Fi's IEEE 802.11.
How does LiFi work?
LiFi is a high speed, bidirectional, and fully networked wireless communication of data using light. LiFi constitutes of several light bulbs that form a wireless network.
When an electrical current goes through to a LED light bulb, a stream of light (photons) emits from the lamp. LED bulbs are semiconductor devices, which means that the brightness of the light flowing through them can change at extremely high speeds. The signal is sent by modulating the light at different rates. The signal can then be received by a detector that interprets the changes in light intensity (the signal) as data. Also when the LED is ON, you transmit a digital 1, and when it is OFF, you transmit a 0.
LiFi Benefits
The primary benefits of LiFi are as follows:
• Security: Provides entirely secure access. Where there is no light there is no data.
• Safety: Does not produce electromagnetic radiation and does not interfere with existing electronic systems.
• Localisation: Allows localisation due to the small coverage area of LiFi access point - localisation can be used for very precise asset tracking.
• Data density: Provides ubiquitous high-speed wireless access that offers substantially greater data density (data rate per unit area) than RF through high bandwidth reuse.

LiFi Systems Reviews by LiFi Tech News
OLEDCOMM LIFIMAX KIT REVIEW - ONE YEAR IN
We reviewed the LiFiMax kit produced by the leading French LiFi company Oledcomm. We bought this LiFi kit system at the end of 2020. After over a year of use, we decided to write a review of this LiFi system. We looked briefly at the profile of Oledcomm, a brief history of the LiFiMax system, the Kit box contents, some testing and performance results of this LiFi system, the customer experience and our own verdict (the good and the bad points) of the LiFiMax kit.

SIGNIFY TRULIFI 6002.1 STARTER KIT SYSTEM REVIEW
We also reviewed the Trulifi 6002.1 starter kit produced by Signify, the world leader in lighting for professionals, consumers and lighting for the Internet of Things. We got this LiFi kit system with the help of PCDSI and Signify around August 2021. In a similar fashion done with our previous review of the LiFiMax kit a few months ago, we will look briefly at the profile of Signify, a brief history of the Trulifi 6002.1 kit, the Kit box contents, some testing and performance results of this LiFi system, the customer experience and our own verdict (the good points and the bad points) of the Trulifi 6002.1 kit.
