Engineers first transmitted data through a laser receiver. This will create super fast Wi-Fi.

A device tested by researchers uses a laser to extract and transmit microwave signals,

which provides a very high data transfer rate.

The laser, unlike the white noise generator,erupting the whole spectrum of sound, it generates it at one frequency - almost like a violin playing an exact note. In a frequency comb, a laser generates multiple beams at several frequencies that are evenly spaced like the teeth of the comb - this allows you to create a so-called infrared laser frequency comb.

For information transfer, researchersmodeled the comb by encoding the data in microwave radiation. The signal was then transmitted via an antenna to the receiving point, another antenna received it, and the computer filtered and decoded.

Previously, MIT engineers presented a flexible device capable of converting Wi-Fi signals into electricity.
