Discover Li-Fi, a new way that can replace Wi-Fi

the WIFI The days could be numbered in the future after a new technology emerges, known as Li-fi. A team made up of several scientists from California Institute of Technology Advertise in Scientific journal A new discovery consisting of a special substance from three atoms.

Wifi is one of the most widely used technologies today

To fully understand the work, we remember that the letter luz exists like a wave It has a property known as polarization. This phenomenon describes the direction in which the waves vibrate.

How was the new material formed?

One of the participants in the study is Harry in the water, Mr Applied physics and materials science, ensures the use of three layers of phosphorous atoms to generate the material and the ability to polarize light, which is adjustablePrecise and accurate.

Liquid crystal display technology is found in phone (s Yes TelevisionsBut the black phosphorous technology has the potential to get ahead of itself. So ‘pixel‘of black phosphorous can be 20 times smaller than that of LCD screens, but with another difference: it will respond a million times faster.

Does Wi-Fi Count Days?

The professor is of the opinion that this new technology can also be used to start an alternative based on light for wifi. Researchers in this field already describe this phenomenon as Technologie Li-Fi.

“Lighting like this very attractive lamp on my desk does not transmit any communication signal. It only provides light. But there is no reason why you should not sit in Starbucks of the future And make your laptop receive a file A light signal for your wireless connection Instead of a radio signal. It’s not yet accessible, but when it does, it will be at least a hundred times faster than WiFi,” Atwater said.
