Oledcomm Corporation redefines the standards of connectivity and internet access with MyLiFi®. Winner of two CES Innovation Awards 2018 in the Tech for a Better World and Smart Cities categories, MyLiFi® is a LED lamp Lifi technology that revolutionizes internet by offering an ultra-fast, secure and radiowave-free connection.
LiFi (“Light Fidelity”) is a new technology that allows mobile devices (and other connected objects) to connect to each other by using LED lights. LiFi transmits data by modulating the light signals from an LED light bulb. Of course, this process is invisible to the human eye. Light signals are received and converted into data by a dongle connected to the device.
This revolutionary technology, created in 2005 by a team including Suat Topsu, President of Oledcomm, had been used for B2B purposes such as helping blind people navigate public transport systems, transmitting medical information in hospitals, and measuring travel times in supermarket aisles. But now LiFi technology is moving into homes and offices as a revolutionary new form of connectivity that is ultra-fast, secure, and that works without any radio waves.
Benjamin Azoulay, CEO of Oledcomm, says,”just as clean energies are displacing fossil fuels and propelling us towards a world of responsible innovation, light is now replacing radio waves to provide a safe, a people- and eco-friendly internet connection. MyLiFi® marks the start of a new era in connectivity. It’s the sense of history!”
“Smart paint” containing fluorescent and phosphorescent pigments could extend the possibilities of proposed LiFi networks, report a team led by K S Narayan at the Jawaharlal Nehru Centre for Advanced Scientific Research in Bengaluru, India. The researchers analysed the effect of nearby luminescent surfaces on the noise characteristics of visible light communication system (VLC) signals, and found that secondary emission could limit bandwidth locally by overwhelming receivers. The residual glow from phosphors could even be modulated to transmit a signal after the primary LED source has been turned off.
LiFi uses visible and near-visible light to connect electronic devices in much the same way as now nearly ubiquitous WiFi. Like its more familiar counterpart, LiFi technology is expected to play a role in connecting devices within the incipient internet of things. Unlike microwaves, however, visible-light signals cannot pass through walls, meaning that LiFi networks are, in principle, less vulnerable to eavesdropping from outside.
“I think it’s not a question of if, it’s a question of when,” Haas told Euronews. “LIFI is a necessity and it will come.
“This is dongle is a real breakthrough that allows us to engage larger scale projects. The pilots we have equipping a number of office environments but now we can equip a full floor of a hotel or an airport.”
How does it work?
Signals are sent via the light stream – at frequencies the human eye cannot detect – to sensors on your device and vice-versa.
But, how does the internet get into the light source?
Haas says there are two solutions and both involve sending data signals down the same cable as the light’s power source.
Wireless Fidelity (Wi-Fi) and Light Fidelity Li-Fi technologies are more demanding in recent time. There are huge business opportunities available to help new players enter the market and to collaborate with big companies to provide various products and services. Particularly for Li-Fi technology, the new start-up market is coming up with advanced products, services and solutions in the market and is expected to double in the next 5 to 7 years. In this space, cooperation and mergers and acquisition laws are expected to continue.
To understand the networking environment, the report Wi-Fi and Li-Fi markets is underlined. The report speaks about the mode, products, services, components, circles and regions deployed for both Li-Fi and Wi-Fi. In the direction of adoption of main stakeholders in the next 5-7 years, information about major trends, drivers, investments, vertical player initiatives and government initiatives can be found. Furthermore, this report gives details of the major challenges that will affect market growth.
As per research report, the Wi-Fi and Li-Fi markets are estimated to witness a CAGR of 15.0% and 61.3%, respectively during the forecast period 2016–2022.
Li-Fi is the abbreviation of light fidelity and was expressed by Harald Hass who was a German physicist. In Li-Fi the information is transferred through light signals instead of radio waves and mostly Wi-Fi plays an efficient role for wireless information coverage within the buildings whereas by using Li-Fi we can provide the excel density data coverage in a particular area without any radio interference issue.
It furnishes well bandwidth, assurance than Wi-Fi and excels speed. In the coming generation, this technology will be used for transmitting data or information to smartphones, laptops etc. through the light in a room.Li-Fi or Light Fidelity refers to 5G Visible Light Communication systems using light-emitting diodes as a medium to high-speed communication in a similar manner as Wi-Fi.
Lighting systems manufacturer Lucibel announced that it has completed its first deployment of ‘LiFi by Lucibel’ in a hospital environment, installing the service in the cardiology department of the Stell clinic in the town of Rueil-Malmaison (Ile de France region). The company said that Li-Fi connectivity is particularly suited to areas within hospitals where the use of Wi-Fi is not recommended or forbidden, due to the risk of interference with medical equipment. The service also offers the additional benefit of providing hospital staff with a secure connection to access patient data.
What if every light bulb in the world could also transmit data? At TEDGlobal, Harald Haas demonstrates, for the first time, a device that could do exactly that. By flickering the light from a single LED, a change too quick for the human eye to detect, he can transmit far more data than a cellular tower — and do it in a way that’s more efficient, secure and widespread.

Wi-Fi networks dependent on radio waves are growing more congested all the time—and can’t be used everywhere—so various researchers and companies are betting light waves from LED lamps and overheads can also stream data and connect people to the internet. So-called Li-Fi technology, which uses a much more abundant slice of the wireless spectrum, is also more energy-efficient than Wi-Fi, though for now people need a special USB drive to use it. Light waves can’t pass through walls like radio waves do, but that also makes the networks more secure. A group from the world’s largest technical association, IEEE, will have draft standards for Li-Fi ready by yearend for companies that want to commercialize the technology, says its chair man, Bob Heile.
1. Setup LEDs outfitted with Li-Fi technology can embed and stream data in the light they emit by modulating the light’s intensity faster than the human eye can detect.
2. Use A USB drive that serves as a receiver and transmitter picks up the signals from the LEDs and uploads data to them from a connected PC or mobile device.
LiFi is not the replacement of WiFi technology. It can be considered as incredible companion of the WiFi technology. It operates between 380 nm to 780 nm optical range. LiFi is used to exchange data incredibly rapidly and securely at much lower power level compare to WiFi.
