When this came in my TimeLine, it was a Today I Learned moment. This is my comment at the end of the article:
Sounds to me that LiFi could be a replacement to or potentially merge with Bluetooth, as both services are high-speed and short range. Needs OS support, such as Android, Windows, and iOS for it to take off, as it uses different transceivers than radio frequencies such as WiFi and cellular.
Brian Sebele looks at Li-Fi, a way to use light signals to send data, and how it fits into the world of the Internet of Things, Wi-Fi and cellular networks.
