Infrared may no longer be the punchline, as IEEE approves 9.6Gbps wireless light

We’ve known for over a decade that flickering light bulbs can move satisfactory That amount of wireless data, not just silent infrared commands to your TV. Now, the IEEE standards body behind Wi-Fi has decided to formally invite “Li-Fi” to the same table — using invisible infrared light to deliver speeds of between 10 megabits per second and 9.6 gigabits per second. Together.

By June 2023, the IEEE 802.11 wireless standard is now officially recognizes Wireless Light communication as a physical layer for wireless local area networks, which is a fancy way of saying that Li-Fi doesn’t need to compete with Wi-Fi. The Lite can be another type of access point and interface that provides the same network and/or the same Internet as your device.

In fact, at least one IEEE member is experimenting with networks that use Wi-Fi and Li-Fi together to overcome each other’s shortcomings, in a bid to improve the network as a whole. Some of the offices move computers to Li-Fi versus Wi-Fi.

Look, Li-Fi products aren’t really new: companies have tried to sell them for years. There already exists a competing standard, the International Telecommunication Union’s G.9991, which appears in Philips Hue maker Signify’s data-beaming bulbs, among other things.

These companies are counting on the fact that the light can provide quick, private, direct-line-of-sight connections without any radio interference – amid concerns that light conditions can vary greatly and accidentally cause line-of-sight connections. Very easy to break. Vision connection. My colleague Jake explains the pros and cons of trying out Li-Fi lamps in 2018.

In writing up its experiment, CableLabs doesn’t deny that Light Communication (LC) has room for improvement. One line in the study reads, “The LC range is very sensitive to radiation and incident angles, making dynamic beam steering (and LOS availability) attractive for future LC development.”

“Enterprise Wi-Fi and state-of-the-art LC performance is on par but LC reliability needs improvement. One possible approach is the use of multiple, distributed optical frontends,” reads another.

Cause we’re listening now It’s not because the IEEE made a big deal about it – it’s because the company that hired Dr. Harald Haas, the man who coined “Li-Fi”, actually wanted to sell their latest product. Fraunhofer, a member of the working group, wishes to be recognized for his contribution.

PureLiFi just launched Light Antenna One In February, a module small enough that it could theoretically be integrated into a smartphone, which it claims can already provide more than 1 Gbps depending on the use case, will be unveiled. (It’s only rated to communicate with devices less than 10 feet away, and it has a 24-degree field of view when transmitting back.) PureLiFi says it’s already compliant with the 802.11b standard. Compliant and ready to enable large-scale integration of LiFi. for the first time.”
