What is the 802.11bb Standard?

The IEEE 802.11bb standard defines the physical layer specifications and system architectures for wireless communication using light waves. It is a line-of-sight light-based wireless networking standard that is part of the 802.11 standards suite, defining an interoperable communications protocol for Li-Fi devices. This standard will allow for communication speeds faster than Wi-Fi. This new standard sets the foundation for the widespread adoption of Li-Fi technology and paves the way for the interoperability of Li-Fi systems with the successful Wi-Fi standard. Development of 802.11bb was carried out by the IEEE 802.11 Light Communications Task Group. Ratification of the standard was concluded in June 2023.

Li-Fi is a wireless technology that uses light rather than radio frequencies to transmit data. By harnessing the light spectrum, Li-Fi can unleash faster, more reliable wireless communication with unparalleled security compared to conventional technologies such as Wi-Fi and 5G. The 802.11bb standard describes using light in the near-infrared 800 to 1000 nm waveband to implement data rates between 10 Mbit/s and 9.6 Gbit/s, with interoperability between devices with different capabilities.

802.11bb, also known as "WLAN Enhancements for Virtual Reality and Augmented Reality," aims to address the unique challenges posed by emerging technologies like virtual reality (VR) and augmented reality (AR).
