What is Li-Fi?

According to Wikipedia: Li-Fi (ˈlaɪfaɪ; short for light fidelity) is wireless communication technology, which utilizes light to transmit data and position between devices.

In technical terms, Li-Fi is a light communication system (hence based on photonics) that is capable of transmitting data at high speeds over the visible light, ultraviolet, and infrared spectrums. In its present state, only LED lamps can be used for the transmission of visible light.

In terms of its end use, the technology is similar to Wi-Fi – the key technical difference being that Wi-Fi uses radio frequency to transmit data.

Using light to transmit data allows Li-Fi to offer several advantages:
  • most notably a wider bandwidth
  • the ability to safely function in areas otherwise susceptible to electromagnetic interference (e.g. aircraft cabins, hospitals, military)
  • offering higher transmission speeds
The technology is actively being developed by several organizations across the globe. Click here for the whole article.

According to pureLiFi: LiFi is high speed bi-directional networked and mobile communication of data using light. Click here for the whole article.

According to Techworld: Li-Fi claims to be 100 times faster than standard Wi-Fi. Li-Fi stands for Light Fidelity and is a Visible Light Communications (VLC) system which runs wireless communications that travel at very high speeds. Click here for the whole article.
