But how did they do it? Researchers are developing 1 terabit per second powerful Wi-Fi!

British researchers have set a new record by transferring data wirelessly at a speed of 938 Gbps. This technology can be used in three to five years.

Researchers fromUniversity College A new record has been set in London. The matterThe matter Wireless transmission, receiving a vitessevitesse 938 gigabits per second (Gbps). In an article published in the journal Journal of Lightwave Technologythey detailed their method which combines radio and optical technologies.

The main wireless technologies, namely Wi-Fi, Bluetooth and 5G, mainly operate at frequencies up to 6 GHz. To achieve such transmission speeds, the researchers had to use a much higher frequency band, ranging from 5 to 150 GHz.

A laser to generate millimeter radio waves

To generate signals for frequency bands from 5 to 75 GHz, the researchers used digital-to-digital converters.AnalogueAnalogue. However, beyond that, the task becomes more complex and above all, keeping the carriers aligned. For this they used technology. OptoelectronicsOptoelectronics To generate radio waves in the millimeter band between 75 and 150 GHz, depending specifically on LaserLaser Frequency locked.

These developments can greatly increase the speed of Wi-Fi and networks. MobilesMobileswhile providing greater stability when a large number of devices are connected to the same network. While the technology is impressive for wireless, it’s still far from the record of 22.9 petabits per second achieved by optical fiber, or about 25,000 times faster.

Researchers have already started working on a prototype for commercial trials. If the tests prove successful, the technology could begin to be deployed within three to five years.
