High-speed fiber optic cables are the backbone of modern telecommunications infrastructure does not deliver the data directly to a computer belonging to the consumer. Affairs that last mile is usually submitted to other intermediaries, such as copper cable or wireless signal.
Well, how about "light" of the fiber optic cable can be made directly reach the various devices that the final destination of data, both computers, smart TV, or so forth?
That's the idea behind an experiment conducted by Oxford University and University College, where "light" as the medium of instruction of data in a fiber optic cable is taken, amplified, and then transmitted wirelessly to a computer that acts like a Wi-Fi network.
From the experimental results, based on information compiled by Kompas Tekno of IEEE Spectrum, Monday (02/16/2015), a system called "LiFi" managed to transfer data at speeds up to 100 Gbps, many times faster than standard Wi-Fi the fastest current (802.11ac) are stuck at a rate of about 7 Gbps.
However, LiFi has the disadvantage compared to conventional methods of Wi-Fi. Although applied through a kind of base station attached to the ceiling of the room, LiFi require a direct line of sight aka "views" directly to the destination device equipped with a special receiver, like infra red connection to the old school gadgets.
Moreover, the goal must be stationary alias should not be moved. The research team is developing a way to create a tracking system that allows the base station LiFi track the position of the device in the room and make a connection.
Because not practical, it is now possible to LiFi still can not replace the WiFi. However, the potential speed of more than 3 terabits, its creators hope this technology will be used for other applications.
