How does LiFi work in a bright room with sunlight?
LiFi can operate in daylight and even in direct sunlight conditions, as the modulated light can still be detected. LiFi
relies on detecting the fast changes in light intensity and not on the absolute or slowly varying levels caused by natural disruptions in daylight or sunlight. LiFi technology modulates the light at very high rates and sunlight is constant light and therefore can be filtered out at the receiver.
Our team at pureLiFi has tested our receivers outdoors under 77,000 Lux of sunlight.
