依靠光线来束在设备之间的数据，LI-Fi是快速安全通信的关键，避免无线电波很重要。French Eart-up最近推出了第一个现成的微芯片，允许任何智能手机，平板电脑或笔记本电脑整合LI-Fi。
什么是li-fi？
Li-Fi is a two-way optical wireless communication technology that offers high-speed, low-latency links over short distances. It relies on LED lights flashing at more than 10 million times per second, making it imperceptible to the human eye.
术语LI-FI在2011年被创造，该技术可以利用类似的Wi-Fi协议。基于轻基的通信不能穿透墙壁，如无线电波，但是作为回报，它们非常有弹性干扰，黑攻击和干扰。
虽然Wi-Fi的无线电波带接近全容量和高度拥塞，但LI-Fi具有几乎无限的容量。理论上可以以每秒高达100千兆位的速度，极低延迟小于1毫秒。
Direct line of sight is not necessary for Li-Fi to transmit a signal, with the light reflected off walls still achieving data speeds of 70 megabits per second.
与Wi-Fi的早期一样，计算机需要USB加密狗利用LI-Fi，但这设置为改变。
French Start-up Oledcomm
At Mobile World Congress 2021, French start-up Oledcomm launched its Gigabit OFE (Optical Front End), the first ready-to-use microchip which allows any smartphone, tablet or laptop to integrate Li-Fi.
千兆位可以与光电二极管和光源相耦合，例如LED或VCSEL，以距离高达5米的距离每秒1千兆位。它可以与专为基础设施设计的ITU-G.9991基带，以及大多数移动设备中已经存在的802.11基带。
Using standard semiconductor analogue technology (250 nm), the Gigabit OFE is less affected by global semiconductor shortage. While Li-Fi is not yet as cost-effective as Wi-Fi, it is a practical replacement in environments where radio waves are not suitable.
The fact Li-Fi can’t pass through walls makes it well-suited to highly secure environments such as government and defence. The Hague’s conference centre has deployed a Li-Fi trial to provide more secure communications.
依赖光而不是无线电波也可确保LI-Fi不会产生可能扰乱敏感设备的RF干扰。
2019年，OLEDCOMM在巴黎航空展上测试了其LI-FI技术。那一年晚些时候，它配备了商用空中客车A321与Li-Fi技术的航班。
li fi在医院中也有应用,avoids interfering with sensitive medical equipment. It is also well-suited to factory floors where it can operate reliably in noisy RF environments.
The Gigabit OFE will allow mobile device manufacturers to seamlessly integrate Li-Fi into their products, says Oledcomm president Benjamin Azoulay.
“最终用户体验将在根本上变化，因为不再需要加密窗。在挑战Covid-19次和半导体能力的全球短缺中，OLEDCOMM展示了其领导力，弹性和承诺，以实现其使命：提供无论是Wi-Fi / 4G / 5G的地方无线电波是不合适的。“
LI-Fi面临的最大挑战之一是协议的标准化。在ITU-G.9991的基础设施标准完成后，该行业正在等待最终确定专用于移动设备的IEEE 802.11bb草案标准。
