Light communication (LC) is an emerging technology that intends to enable high speed internet access and works on the principle of intensity modulation of existing solid-state lighting infrastructure, often involving light-emitting diodes (LEDs). LC offers several key advantages over traditional radio-frequency based access networks.
Speed & Bandwidth | Multiple Gbps, full bandwidth available to multiple users.
Low Latency | Typically lower latency than radio frequency, reduced buffering, no dropout.
Near Zero Electromagnetic Signature | Unlike radio frequency LC has a near zero electromagnetic signature.
Quality of Connection | Interference free 1,000x data density.
Military Grade Security | Physically contained and immune to interference.
Unlicensed Spectrum | LC operates in spectrums which are not subject to licensing in any country.
Li-Fi is a wireless communication technology which utilises light to transmit data and position between devices. LCA member pureLIFI explains more in the video below:
Optical camera communication
Optical camera communication (OCC) refers to the wireless communications between optical sources and cameras (image sensor). Camera image sensors are used to receive data from light emitting diodes. This technology can be implemented in all cameras as well in smartphone as it has the capability of image processing.
