The next major step in data transfer via FTTD (Fiber To The Device) is being prepared by a team of researchers at the University of Oxford. The technology they are developing is based on the Li-Fi (Light Fidelity) standard, receiving data in the form of light via optical fibers.
The system he has is as follows: A projector is placed on the ceiling, and transmits the data directly to the computer, requiring that there be no obstacles between the two, as is the case with infrared rays.
The team is already looking at ways to overcome this limitation, as it is not practical at all. Of course, the communication is two-way, allowing the computer to also send data.
Data from the ISP to the home will come at a speed of 100 giga-bps, while theoretically this speed will be able to reach 3 tera-bps.
Currently, the highest speed supported by Wi-Fi, with specific equipment and in ideal conditions, is just (!) 7 giga-bps.
