bulbs that, in addition to light, give Internet

We’ve been hearing about LiFi technology for a while now, but it’s taken a while to roll out. Today, companies like pureLiFi They already have everything they need to bring that luminous connection into homes. It will be very helpful for home Wi-Fi to finally cover that corner where there is never any coverage.

LiFi technology is not very difficult to explain. It involves transmitting data by using parts of the light spectrum that are there but that we do not see or serve us for anything concrete. Light bulbs, for example, emit part of their light in the infrared spectrum. LiFi technology takes advantage of this light that we do not see to transfer data and provide us with another connection system. By its very nature, LiFi is not intended to replace the usual WiFi. For example, it cannot pass through walls, which does not make it suitable for plugging in an entire house unless you change all the light bulbs. On the contrary, it is a technology with the same vocation as automatons, that is to say, to support general connections using a technology, artificial lighting, which is already omnipresent in all civilized place.

ANDThat same quality of not walking through walls too makes it extremely secure because the device receiving the signal must be within the range of light to receive data. The question, of course, is which devices are capable of receiving a LiFi connection? We had the answer in our hands at the last Mobile World Congress: whatwant equipped with small component like these Pictures.

LiFi plug-in modules can be installed as part of any other device, from tablets to cell phones to TVs. For the test we attended at the pureLiFi booth, what they had done was simply add a box with this chip to a conventional mobile and connect another receiver to a TV.

For both to work, the stand lights must be emitting a LiFi signal. For this, a bulb equipped with another small circuit acting as an emitter is sufficient. The connection does not require any specific software because something like a mobile interpreter LiFi networks just like you would with regular WiFi. You just have to choose which one to connect to. In the case of having several at the same time, the mobile itself would choose the one with the best signal at all times.

At the commercial level, pureLiFi will not sell termi LiFi devicesn / Atwo for the general public. Its objective is to resell the components to other manufacturers so that they can integrate them into their devices. The receiver and transmitter can carry other components as long as they let light through (screens, glass backs…), so LiFi doesn’t compromise things like water resistance. The system is now ready for use, so it’s only a matter of time before we see bulbs capable of emitting the Internet and devices capable of picking up this connection.
