We talked about Bluetooth, we talked about Wi-Fi, but do you know about Li-Fi? Discovery…
What is Li-Fi?
Unlike Wi-Fi or Bluetooth, which use radio waves, Li-Fi, or Light Fidelity , is a new means of very high-speed wireless communication using light. The principle is based on LED technology, which is increasingly used in our homes and public lighting (low-energy bulbs). The LED is not only capable of emitting light, but can also flicker at a frequency of 1 GHz, undetectable to the human eye, and thus transmit a very large amount of information.
Li-Fi communicates with a mobile phone using a micro USB key; it is a simple and inexpensive technology. International standards have begun to be put in place to equip smartphones with Li-Fi.
The Li-Fi market is estimated to be worth $6 billion in 2018 .
Why Li-Fi?
Faced with the growing demand for mobile connections, the 4G costa rica mobile database offer will inevitably be limited by the available frequency band. In addition, the superposition of several Wi-Fi frequency bands will saturate and create interference for the many connected objects of tomorrow (as a reminder, the European standard limits radio emissions to 3V per meter).
And since 5G will ultimately only be a rapid adaptation by switching the antenna of our mobiles to the best available frequency between 3G, 4G or Wi-Fi, the Li-Fi system will offer the possibility of connecting to the Ethernet network .
Without replacing Wi-Fi or 4G, Li-Fi will be complementary and much better suited to an indoor and geolocated nomadic activity: the light of Li-Fi is limited only by its distance (up to 10 meters without loss of signal quality) and the surface of its lighting. A bulb that can light up to several dozen mobiles, all the travelers in an airport, all the customers in a large store, and all the mobile users in a shopping mall, will be able to communicate through the continuous mesh of Li-Fi lighting.

What are the applications of Li-Fi?
Today, just like Wi-Fi a few years ago, it is public spaces and the transport sector that are developing Li-Fi services. Airports and train stations, but also trains, planes, and automobiles. Thanks to Li-Fi, lighting hours are not only a cost, but also a communication and revenue tool.
Li-Fi is the systemmartechideal for sending push notifications to mobile users as soon as they enter a shopping area. It is possible to communicate continuously and build loyalty through targeted offers thanks to the data collected and the purchase history. 30% of impulse purchases result from targeted promotions.
