Is it finally practical?"LIFI" communication technology that is connected by light of lighting, not radio waves

LIFI not Wi-Fi."LIFI" refers to "Light Fidelity" and is a light radio communication technology using LED, which is much faster than WiFi.Although this LIFI technology has existed for a long time, it has become 2022 without any practical use, but specialized companies like Purelifi have finally worked hard to spread this new wireless communication technology to the home.I came to the place ...

Wireless technology that uses light, not radio waves

First of all, if you talk about what LIFI is, Wi-Fi uses radio waves, but Li-Fi is a wireless communication that uses visible light.For example, a light bulb radiates a part of the light with infrared rays, but LIFI technology is to transfer data using its invisible light, and the infrared wave and ultraviolet rays of LED bulbs switching at ultra -high speed.Use the optical spectrum.LIFI is not intended to replace the normal WiFi communication due to its nature.Since the light cannot pass through the wall, it seems difficult to cover the whole house with LIFI alone unless you replace all the light bulbs.It is a technology for supporting wireless connection by installing LIFI on existing light bulbs, such as street lights.In addition, it is also characterized by high safety (difficult to intercept) because the data cannot be received unless the equipment receives the signal is within the range of light.The current problem is which terminal can be connected by LIFI, but if it is a device equipped with a small component such as the TOP photo, it will be possible to connect (but it will spread).

The actual product is now

The LIFI connection module can be installed as part of any device, such as tablets, smartphones, and television.This time, at the Mobile World Congress Purelifi booth, a test was conducted to connect another receiver to a TV with a case equipped with this module on a conventional smartphone.In order to be able to use both, it is necessary to be within the light that emits the LIFI signal from a standlight equipped with a light bulb equipped with a small circuit that works as an emitter.Smartphones and the like interpret the LIFI network in the same way as normal Wi-Fi, so there is no special software for connection.All you have to do is select which network to connect from the network connection screen.If you connect to multiple networks at the same time, always select a good smartphone in a good radio wave state.Purelifi aims to sell components to other mobile manufacturers, etc., instead of selling LIFI -equipped devices to general consumers and incorporated them into manufacturers.Both the receiver and the emitter can be mounted on the light (such as display, glassback, etc.).The system has been commercialized.
