New Phosphor Blend for LEDs Could Crank Up Li-Fi Speed

Adding perovskite to the material that converts blue LED light into white boosts visible light communication modulation rates by a factor of 40, researchers find, improving the capabilities of Li-Fi. VLC uses the invisible modulations in LED lightwaves to transmit data via the lightwaves. It is the technology behind Li-Fi, the light-based alternative to radio-based Wi-Fi, for wireless Internet transmission. Supporters of Li-Fi and its underlying VLC technology say that it will add enormous capacity to wireless communications, because the visible light spectrum is 10,000 times larger than the radio frequency spectrum that Wi-Fi uses. http://www.ledsmagazine.com
