#ScienceTech_IP LiFi Technology : EveryThing You Need To Know Imagine a world where every light could connect you to the internet. Lights that illuminate our offices, homes, cars and our streets also connecting us to data and powering our growing demand for connectivity. LiFi allows for data to be transmitted by modulating the intensity of light, which is then received by a photo-sensitive detector. The light signal is then demodulated into electronic form. This modulation is performed in such a way that it is not perceptible to the human eye. LiFi can work indoors, outdoors, with the lights dimmed and is not strictly line-of-sight technology. pureLiFi’s technology is also LED agnostic which means it works with many off-the-shelf LED’s. The way LiFi works is simple but powerful. When a constant current is applied to an LED light bulb, a constant stream of photons are emitted from the bulb which is seen as illumination. LED bulbs are semiconductor devices, which means the current, and therefore the illumination can be modulated at extremely high speeds which can be detected by the photo-detector. Using this technique allows for high-speed information can be transmitted from an LED light bulb. Radio frequency communication requires radio circuits, antennas and complex receivers, whereas LiFi is much simpler and uses direct modulation methods similar to those used in low-cost infrared communications devices such as remote control units. LED light bulbs have high intensities and therefore can achieve very large data rates. APPLICATIONS & BENEFITS The applications for LiFi are limitless. Anywhere there is an LED light there can be data. LiFi is a platform technology that will extend the capabilities of wireless communications to places beyond even our current conception. Today there are real life applications and benefits for implementing LiFi. LiFi can enable secure wireless communications, connectivity in RF hostile environments such as petrochemical plants and hospitals. LiFi also provides high speed, dense and reliable networks for enterprise environments and a pathway to enable smart buildings, transport, cities, and nations.
