Li-Fi speed up to 224 GB/s
The Institute of Electrical and Electronics Engineers (IEEE) has adopted 802.11bb as the standard for light-based wireless communications. The new standard is called Li-Fi.
The authors emphasize the benefits of using light rather than radio frequencies. Li-Fi provides “faster, more reliable wireless communications with unparalleled security than conventional technologies such as Wi-Fi and 5G.”
It is reported that Li-Fi will not supplant Wi-Fi and 5G or wired networks. Radio waves still have a clear advantage in terms of transmission through the atmosphere over long distances and through opaque objects. However, the new technology can be used indoors, providing the highest speed and lowest latency.
100 times faster than Wi-Fi: Li-Fi standard adopted
The video shows how a Li-Fi system can be integrated into a building’s lighting system for data transfer. Part of the infrared spectrum is used for data transmission, so people won’t see any flicker or anything like that.
Li-Fi speed reaches 224 GB / s. Fraunhofer’s Dominik Schulz points out that since Li-Fi operates in an exclusive optical spectrum, this results in higher reliability and lower latency.
“Line-of-sight light propagation improves safety by preventing penetration through walls, reducing the risk of interference and eavesdropping, and enabling indoor navigation with centimeter accuracy,” says Dominik Schultz.
