Wireless connection 100 times faster than Wi-Fi

Li-Fi, the 802.11bb wireless transmission standard, achieves an ideal speed of 224 Gb/s, 100 times faster than current Wi-Fi.

According to the announcement of the Association of Electrical and Electronic Engineers (IEEE) on July 13, 802.11bb has been added to the list of new wireless network transmission standards. The move is welcomed by global Li-Fi businesses, as it will help speed the deployment and adoption of this new data transfer technology standard to life.

Currently, the latest Wi-Fi standard has evolved to 802.11be, also known as Wi-Fi 7, with the highest speed of 30 Gb/s, three times faster than 9.7 Gb/s on Wi-Fi. 6. Meanwhile, the current popular Wi-Fi standards are 2.4 GHz and 5 GHz, for speeds ranging from 200 Mb/s to 1.3 Gb/s.

If Wi-Fi uses radio waves (RF) to transmit data, Li-Fi uses light wave technology, more specifically, light signals to transmit data through LEDs. As a result, the speed achieved is much higher, ideally 224 Gb / s, and at the same time does not interfere with medical equipment, does not affect or conflict with existing radio waves.

With this advantage, Li-Fi has long been appreciated by experts for its faster, more reliable and safer wireless communication than Wi-Fi and 5G. However, the weakness of this technology is that it is limited if there are obstacles such as walls, or places with low light.

According to Tom's Hardware , there are advantages, but Li-Fi will not have the potential to wipe out radio-based network technologies like Wi-Fi or 5G. Radio waves still have a huge advantage in traveling through the atmosphere at great distances and through objects. Instead, Li-Fi will be exploited in cases of high-speed data transmission at close distances and few obstacles.

"Light technology's linear data transmission capabilities on Li-Fi increase security, reduce the risk of interference and eavesdropping, and enable centimeter-accurate indoor navigation," Dominic said. Schulz, an expert at Fraunhofer HHI, one of the pro-Li-Fi organizations, said.

To date, several companies have started to produce Li-Fi modules for transmitters and connected devices. Among them, pureLiFi provides the Light Antenna ONE module 14.5 mm thick for OEMs to test and evaluate. Commercial Li-Fi devices are expected to make their first appearance at Mobile World Congress - MWC 2024 in Spain.
