A unique technology is around the corner, potentially changing how we connect to the internet. What seems like something out of a sci-fi movie might offer different advantages than traditional Wi-Fi. Although it is still too early to say what this means for broadband in our homes, it does offer promise as well as certain limitations. What is this new technology, where is it available, and how does it work?
What is Li-Fi?
Light Fidelity, also known as Li-Fi, uses the power of light to transmit data. Yes, you heard that correctly: This technology harnesses light signals to connect to the internet. Unlike Wi-Fi, which uses radio waves to create a wireless connection, Li-Fi relies on light to transmit data. Through this process, Li-Fi promises speeds that are 100 times faster than Wi-Fi.
Research for Li-Fi has been around since the early 2000s. Alongside his team, German physicist Harald Haas founded this technology by discovering that light can be used for two-way data transmission. It wasn’t long before French company Oledcomm, one of the global leaders in this technology, began conducting its experiments on Li-Fi in 2008. In July, Europe launched Ariane 6 into space, carrying out four experiments, one geared toward testing Li-Fi technology.
How does Li-Fi work?
Li-Fi technology would benefit many sectors like defense and government, increasing the ability to transmit data securely.

The LiFi Group describes this technology to be crucial for sectors like defense and government, which is optimal for transferring data securely. For instance, the emergence of Vibrint LiFi in April of last year has led to the use of Li-Fi to promote secure communication among government and national security organizations. Other industries, like aviation, are also making rounds, as seen with Spectrum Networks LLC, which is based in Fife, Washington.
Moreover, there is an increased interest among US companies that are funding research to develop this technology. VLNComm, based in Charlottesville, Virginia, is a leader in VLC technology and pivotal in developing Li-Fi. In addition, the company Signify, known for its energy-efficient lighting products, is also a key player in VLC technology. This company is headquartered in the Netherlands, but its North American corporation is nestled in Bridgewater, New Jersey. Both companies are doing work that will lay down the foundation of Li-Fi technology.
What’s next for Li-Fi?
‘We’ve been in discussions with several leading companies, not only within the Li-Fi and wireless communication sectors but also across industries such as consumer electronics, automotive, telecommunications, logistics and more,” says the LiFi Group spokesman. “The growing demand for innovative connectivity solutions, especially in environments where traditional wireless technologies face limitations, will likely drive more companies to explore and invest in Li-Fi in the near future.”
What’s the bottom line on Li-Fi?
Li-Fi technology seems like a great alternative to Wi-Fi and, in theory, might benefit many industries. It’s still too early to say that this technology will replace Wi-Fi as a whole. It might take some time before we actually see tangible evidence of its impact on wireless connectivity. Li-Fi is promising, as we see increased interest among companies in introducing new products and funding research to develop the standard. Until then, we’ll keep you up-to-date on new developments with this technology.
‘What is Li-Fi’ FAQs
Wi-Fi uses radio waves to create a wireless connection, whereas Li-Fi uses light signals to transmit data. Li-Fi offers different advantages than Wi-Fi, such as the ability to transmit more data at an accelerated rate, resulting in speeds that are 100 times faster than Wi-Fi. The main advantage of Wi-Fi is it offers a broader range of connectivity since radio waves can pass through walls. Li-Fi, on the other hand, relies on a direct line of sight for light signals, meaning your connection will be confined to closed spaces.
Where can I find Li-Fi?
Trulifi 6002 is a new product introduced by Signify and the LiFi Group. This product utilizes Li-Fi technology to connect to the internet. It boasts faster speeds than Wi-Fi and lower latency, which is suitable for avid gamers. While we wait for Li-Fi to hit the mainstream, Trulifi is available nationwide, making it a good opportunity to try out the technology. Installation is also quick and easy, a LiFi Group spokesperson tells CNET.
The downside is that this product requires many different parts that are significantly pricier than Wi-Fi. The Access Point, the central unit that powers your Li-Fi network, costs $770. You may pay upwards of $1,000 in total, including the required parts, just to get started.
Is Li-Fi good for online gaming?
Li-Fi has its advantages, but it also poses certain limitations. Li-Fi technology has limited range and compatibility and won’t solve the slow internet speeds caused by your ISPs. The main disadvantage of Li-Fi is that it relies on a direct line of sight of light signals to power your connection. Why does this matter? Li-Fi’s line of sight requirement can pose challenges for the many Americans who commute or travel daily.
