IEEE officially signed the 802.11bb wireless transmission standard (Li-Fi) on July 13, which can be based on light wave wireless transmission technology.
Compared with Wi-Fi 7, the theoretical speed can reach 30bps, and it can achieve up to a few meters in the room. 224GB/s data transfer. The technology, led by pureLiFi and supported by Fraunhofer HHI, was approved as the 802.11bb standard last month.
The new IEEE 802.11bb standard defines the physical layer specification and system architecture for wireless communications using light waves. Li-Fi utilizes a portion of the proprietary infrared spectrum in lighting for transmission at speeds up to 224GB/s. That is, the more light in the room, the faster the connection.
Since the frequency exceeds 60Hz, it cannot be detected by the naked eye. Li-Fi networks are said to have data rates per square meter, or area, that can be 1,000 times higher than Wi-Fi networks.
Scientists and researchers have tested Li-Fi in office and industrial environments, reporting data transfer rates of 1GB per second. That is, it is likely to exceed the speed of other Internet connections available to us. It is believed that the use of Li-Fi can help solve users’ demand for big data.
But Li-Fi has limited penetration and cannot penetrate opaque objects. Although this has certain limitations, it also ensures the absolute speed and absolute security of communication within a certain range. So Li-Fi won’t replace Wi-Fi and 5G alternatives, including wired networks.
At present pureLiFi has begun to supply antenna components to OEMs, and is testing Li-Fi systems in architectural lighting and street lighting.
