Li Fi is a bi directional, high speed and fully networked wireless communication system like wi fi.This coined by Prof. Harald Haas.Li Fi is a optical wireless communication technology,and its a replacement to all communication technology like RF Communication like wi fi,cellular networks and all data broadcasting systems.
Li Fi is wireless and its use light spectrum to works like visible,infrared and ultraviolet instead of RF {Radio Frequency} waves. [wave spectrum behind the working of wi fi and cellular networks.]. Because of the bandwidth limitations in radio frequency waves Li Fi can carry more information.
LED bulbs are used to transmit data as light,and major merit is it can on or off with in nanoseconds look on the given picture and look how it works.
Li Fi has a major advantage that is we can use it in electromagnetic sensitive area such as hospitals,Aeroplanes,Nuclear power plants and place like this, Because Li Fi is work over Electromagnetic Spectrum.Data transmitted through the Li Fi technology is highly secured because there is less possibility of Hacking or Tapping { whether it is wi fi or cellular networks its possible to do that}.So Li Fi ensure more security than other data communication mechanism.
Pure Lifi demonstrated the first commercially available Li Fi Systems.
"pureLiFi, the home of LiFi, is recognised as the leader in the field – the use of the visible light spectrum instead of radio frequencies to enable wireless data communication. pureLiFi provides ubiquitous high-speed wireless access that offers substantially greater security, safety and data densities than Wi-Fi along with inherent properties that eliminate unwanted external network intrusion. In addition, the integration of illumination and data services generates a measurable reduction in both infrastructure complexity and energy consumption."
LiFi is a disruptive technology which will shift business models and create opportunities ripe for exploitation. The dominance and lifetime of LED lighting has created a need for new business models in the lighting industry. The need to offer services, including new payment and financing models, creates an unprecedented opportunity for LiFi.
The need for more capacity for mobile communications has an incredible impact on the need for more spectrum. Specifically, the pending decision on the auction surrounding the 700MHz part of the spectrum in the UK and the possibility of regulation of the unlicensed spectrum, where Wi-Fi and Bluetooth thrive, provide key indicators as to the urgency of the problem. LiFi operates in the unlicensed and safe visible light spectrum where the spacial reuse of bandwidth results in dramatic increases in the overall capacity of a wireless solution.
At pureLiFi, the home of LiFi, we aim to address and optimally exploit the opportunities presented by this disruptive technology in conjunction with our LiFi ecosystem partners.
I think it should be a great success
