Oledcomm introduced the first LiFi connected object in the world in CES

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!”

You could soon be surfing the web via lights

A inventor from Germany has claimed a major breakthrough in revolutionising how we access the internet.

Harald Haas is the man behind LIFI – a technology which allows internet data to be sent and received via LED lights.

His company, Pure LIFIhas recently released a USB dongle device that enables laptops and tablets to be connected to the burgeoning technology.

“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.

Li-Fi Analysis on United States Market and Global Research in 2017

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.

Li-Fi The Internet Using LED Light Waves

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.

3. Privacy Because light, unlike radio waves, can’t penetrate a wall, Li-Fi isn’t as all-purpose as Wi-Fi. But it’s more secure.


Innovators Harald Haas and Mostafa Afgani: co-founders (chief scientific officer; chief technology officer)

Founded 2012 Based Edinburgh

Funding £9 million ($11.4 million)

Background Haas, a professor at the University of Edinburgh, became a public face of Li-Fi research with a 2011 demo in a TED Talk. The lecture has been viewed online about 2.4 million times.

Status The 25-employee startup is testing its technology with customers including Cisco Systems and British Telecommunications. Afgani says it transmits data at up to 43 megabits per second. (The average U.S. broadband speed is about 16 Mbps, cloud-services company Akamai Technologies estimates.) PureLiFi has also partnered with French lightmaker Lucibel, which introduced its Li-Fi-equipped overhead lights in the fall and plans to unveil the next model by April.


Innovators Mohammad Noshad and Maite Brandt-Pearce: co-founders (chief technology officer; adviser)

Founded 2013 Based Charlottesville, Va.

Funding $1.6 million

Background University of Virginia professor Brandt-Pearce and former student Noshad, who recently completed a postdoc at Harvard, spun VLNComm out of their optical communications research.

Status Co-founder Fraidoon Hovaizi says their nine-person team, backed by the U.S. Department of Energy and the National Science Foundation, has been in funding and partnership talks with U.S. government agencies and companies including Lockheed Martin. Their latest overhead-light prototype is as fast as 25 Mbps; Brandt-Pearce says the next one will hit 100 Mbps given their advances in coding, modulation, and signal processing. VLNComm plans to bring a Li-Fi-capable desk lamp to market this year.


Innovators Deepak Solanki and Saurabh Garg: co-founders (chief executive officer; chief technology officer)

Founded 2012 Based Tartu, Estonia

Funding Declined to disclose

Background Hardware developer Solanki and software developer Garg started working on Velmenni in India. The 11-person team has created a credit-card-size prototype router capable of converting off-the-shelf LED lights into Li-Fi transmitters.

Status Solanki says the technology can reach 10 Mbps today and will reach 100 Mbps by yearend. Velmenni, which completed an Airbus business-accelerator program in Hamburg in 2015, says it’s developing Li-Fi applications for airplane cabins and cockpits with clients it declined to name, as well as hardware for outdoor use.

What is the LiFI internet architecture

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.

Below is the internet architecture diagram flow
