Today, the Institute of Electrical and Electronics Engineers (IEEE) has added 802.11bb as a standard for light-based wireless communications. The publishing of the standard has been welcomed by global Li-Fi businesses, as it will help speed the rollout and adoption of the data-transmission technology standard.
Advantages of using light rather than radio frequencies (RF) are highlighted by Li-Fi proponents including pureLiFi, Fraunhofer HHI, and the Light Communications 802.11bb Task Group. Li-Fi is said to deliver “faster, more reliable wireless communications with unparalleled security compared to conventional technologies such as Wi-Fi and 5G.” Now that the IEEE 802.11bb Li-Fi standard has been released, it is hoped that interoperability between Li-Fi systems with the successful Wi-Fi will be fully addressed.

Where Li-Fi shines (pun intended) is not just in its purported speeds as fast as 224 GB/s. Fraunhofer’s Dominic Schulz points out that as it works in an exclusive optical spectrum, this ensures higher reliability and lower latency and jitter. Moreover “Light’s line-of-sight propagation enhances security by preventing wall penetration, reducing jamming and eavesdropping risks, and enabling centimetre-precision indoor navigation,” says Shultz.

One of the big wheels of Li-Fi, pureLiFi, has already prepared the Light Antenna ONE module for integration into connected devices.
