LED and Laser Wifi replacement can boost speeds to 100 gigabits per second without interference

Mainstream adoption of LiFi will be available within LED light bars which will replace the most widely utilized light source in the world – fluorescent tubes.

The introduction of the first LED “light bar” is forecasted to replace the most conventional form of lighting within commercial and industrial facilities: fluorescent tubes; with an estimated 3-4 billion installed throughout the world.

pureLiFi and Linmore LED will demonstrate this new technology at LuxLive from the 15-16th of November as part of their LiFi experience zone.

Wireless connectivity is evolving. The spectrum now has to accommodate more mobile users and is forecasted to increase to 20 Billion devices (forming the IoT) by the year 2020 which will result in what is known as the Spectrum Crunch. However, LiFi can open up 1000 times more spectrum for wireless communications to combat this phenomenon. LiFi is a transformative technology changing the way we connect to the Internet by using the same light we use to illuminate our offices, home and even streets.

Integration of LiFi within LED strip lights will drive mass adoption, enabling LiFi to easily move into full-scale implementation within offices, schools, warehouses and anywhere illumination is required.

LiFi is high speed bi-directional networked and mobile communication of data using light. LiFi comprises of multiple light bulbs that form a wireless network, offering a substantially similar user experience to Wi-Fi except using the light spectrum.

In March, 2017, PureLiFi LEDs achieved peak rates of 15 gigabits per second. In real-world settings, the company’s products deliver data rates of about 45 Mbps for both uploads and downloads. For comparison, the average broadband Internet connection in the U.S. offers download speeds of 54 Mbps, while mobile Internet service provides about 20 Mbps. Upload speeds are significantly slower.

At pureLiFi they are innovating LiFi technology and driving adoption. They launched the very first commercially available LiFi product to the market in 2013. Since then pureLiFi has launched three generations of LiFi systems that have spearheaded miniaturization and overall functionality of LiFi technology.

Market research indicates that LiFi will become a $75 billion industry by 2023. Minimal changes to the existing 802.11 protocols will increase their reach into this new market.

While LED-based Li-Fi could reach data rates of 1015 Gb per second, an improvement over the Gb per second maximum of Wi-Fi, using lasers could boost that speed to “easily beyond 100 Gb per second,” Haas says.

  1. So, if I understand this properly: you should be able to create a file that, if anyone in the room downloads it through the LiFi, it will cause seizures in all the epileptics in the room.

    • I have no idea why you would come to that understanding. The article says nothing about epilepsy, seizures, or the need to use frequencies that would negatively impact human health.

  2. According to the purelifi website their product currently offers 43 mbit/s bandwidth. It also needs line of sight.
    Two years ago, the situation was pretty much the same. While their may be a specific market niche where light based data transfer is required, so far they cannot compete with basic gigabit wifi.
    Based on the last two years’ slow innovation rate, I doubt they will succeed in the near future.
