Wi-Fi technology remains officially in the past. Replaces Li-Fi – wireless technology that uses light to transfer data with a speed of 1GB/s. The technology is already being tested in real conditions in offices in Tallinn, Estonia, and 100 times faster than the mass currently in use Wi-Fi. Was first invented in 2011 from Harld Haas /Harald Haas/ University in Edinburgh that demonstrates primagama light from a single LED source provides more information than a mobile cell. Then in the laboratory achieved a speed of 224 GB/s, equivalent to 18 per second movie at 1.5 GB each.
The technology uses a visible light device, which uses visible light with a frequency of 400-800 ТHz. Light flashing very quickly, prebyvanie can't be seen by the human eye.
The advantages of this technology are that light cannot pass through solid objects such as walls, which makes it much safer to use. This also means that decreases and interaction between the components. As you may have guessed, the main disadvantage is that one Li-Fi is almost always not enough for good signal coverage.
