Li - Fi Technology

Li-Fi is wireless communication technology, that utilizes light to transmit information and position between devices. The term was 1st introduced by Harald Haas during a 2011 TED Global talk in Edinburgh. 

Li-Fi is a derivative of optical wireless communications (OWC) technology, that uses light from light-emitting diodes (LEDs) as a medium to deliver networked, mobile, high-speed communication in a similar manner to Wi-Fi. LiFi covers distance of about 10 meters while WiFi covers about 30 meters.

There's a great deal of potential for LiFi in india, as a lot of internet devices are being added into the connected system daily, leading to radio networks turning into congested. With more and more digital content being consumed through mobile devices, within the future, customers will demand a quicker internet connection which will be easily enabled through LiFi.

Advantages of Li-Fi Technology

1. Secure: radio frequency will trespass through wall however light doesn’t, thus information are safer than now. User will see wherever the data is going.                                              
2. No interference: radio frequency technology like Wi-Fi is liable to interference from a wide range of devices like cordless phones, microwaves and neighboring Wi-Fi networks. Interference is much easier to avoid and even stop altogether while using Li-Fi technology.                                                                                                                                                
3. Smart lighting: smart lighting can facilitate the atmosphere (both indoor and outdoor) looks well, at the same time providing smart hotspot to the devices.                                   
4. Cost: Li-Fi price is minimal as compared to Wi-Fi technology.
