In the era of 5G technology, SLD Laser, a company proved that instead of using radio waves, laser light can speed-up data transfer at a tremendous rate.
SLD, the company, presented a demo of its latest version of laser light called Laser LiFi at the CES 2020 in Las Vegas. The basic idea behind the laser LiFi network is to use optical communications in place of radio frequency transmissions used by WiFi. The company’s idea is to place Li-Fi routers on ceilings, which will use the light from LEDs to stream data around a room at a speed of up to 100 gigabits per second, which is much more higher than what the faster WiFi can achieve.
In the presentation at the CES, the company revealed that data can be transferred at a speed of 20 GB/s. The 5G wireless network that is pertaining to the marketplace assures data transfer speed of just 1 GB/s. In the future, it might increase to 10 GB/s.
The use of lasers instead of LEDs to transfer data improves the efficiency of the innovation, as the laser can be managed at a much faster rate, and the optical power of the lasers can be higher. Now, lasers can be unsafe to the eyes of people. To prevent eye damage, SLD is utilizing blue-emitting lasers to excite phosphor that produces white light. This will cut the power to the eye-safe level and still manage the advantages of lasers over LEDs.
With the development of LiFi technology, communications can be transferred beyond the rate of 5G tech. It will make it possible for communication between two autonomous cars, to move a large volume of data around factories and smart homes, let drones send hi-resolution photos to the ground, and more.
