The Future Of Connectivity
LiFi is high-speed, bi-directional, full duplex and fully networked wireless communication of data using light. LiFi comprises multiple LED light sources that form a wireless network. When an electrical current is applied to an LED light, a stream of light (photons) is emitted from the source. LED lights are semi-conductor devices which mean that the light frequencies that are being emitted can be modulated at extremely high speeds. The modulation of the light frequency at different rates effects the transmission and then reception of a signal by a detector which interprets the changes in light intensity (the signal) as data. The intensity modulation cannot be seen by the human eye.
The applications of WiFi technology and overwhelming demand for data in the information age of global connectivity are increasing exponentially and while WiFi has dramatically changed our lives, it has also produced a situation where available data capacity is now rapidly reaching its radio frequency bandwidth limits. This is ensuring that the bandwidth capacity for the WiFi radio frequency transfer of that data is rapidly reaching its limits.
LiFi is currently not only THE ONLY viable answer to our growing need for increased wireless data capacity, but it also offers a far more secure, far faster and higher capacity method of wireless communication with substantially better data densities.
Whereas WiFi technology effects data transfer utilizing radio waves, LiFi takes the next revolutionary step in wireless evolution and embeds and transfers data in visible light beams, thereby allowing LiFi to take full advantage of the vastly greater light spectrum bandwidth capacity that is provided by the light spectrum.
Data is captured in modulated light frequencies of a solid-sate LED light source and is then transmitted and received by LiFi-enabled devices. A photosensitive detector demodulates the light frequency signal and converts it back into an electronic data stream and – in so doing – allows for faster-than-ever, more secure, bi-directional wireless communication.
