Soon you will get 100 Gbps speed into your computer with Li-Fi Like Systems
Earlier the data which was transferred to our computer was not accurate and had drops while travelling a long way to its final destination that is you. The data which travelled in the form of light has certain drops in midway due to various reasons. Now, researcher believe it’s all over.
How would it sound if we take the light all the way to the computer or TV, projecting it through the air over the last few meters and only converting it to an electronic signal at the end? That sounds amazing isn’t. The researches at Oxford University is working on the similar technique with a system that takes light from the fiber, amplifies it, and beams it across a room to deliver data at more than 100 gigabits per second.
Ariel Gomez, a Ph.D. student in photonics at Oxford University who describes the system in IEEE Photonics Technology Letters says that such indoor optical wireless probably wouldn’t replace Wi-Fi, but if compared with data rates of 3 terabits per second and up, it’s certainly amazing and could find its uses. Wi-Fi, by contrast, can give a maximum top speed of about 7 Gb/s. And with light, there’s no worry about sticking to a limited set of radio frequencies. “If you’re in the optical window, you have virtually unlimited bandwidth and unlicensed spectrum,” Gomez says.
So to use this feature, you need to install a base station on the ceiling of a room, which would project the light toward the computer and also receive data heading out from the computer to the Internet.
The transceivers should be mounted with a wide field of view to make the alignment task easier, because the device relies on wavelength division multiplexing, which splits the signal into slightly different colours of light. Just like a prism, which diffracts the light into several colours, the diffraction grating of the beam steerer bends each wavelength a different amount. With a 60
