Li-Fi, the wireless alternative to using light, has successfully completed its first commercial test.
Li-Fi, the technology for transmitting wireless information by light, newly installed in the offices of the Estonian start up Velmenni. With Li-Fi, the company can now enjoy a rate 1 GB per second.
Li-Fi, the Internet by light
Li-Fi is a wireless communications technology that is based on the use of visible light. Instead of using the radio portion of the electromagnetic spectrum as does the Wi-Fi, the Li-Fi uses the visible range of the electromagnetic spectrum. In other words, the encoding and transmission of data are carried out via modulation of the amplitude of the light sources. The Li-fi therefore allows for a safer Internet access, because the data that travels over a defined area. This technology is also healthier for health as Wi-Fi because it uses no waves can penetrate walls and therefore the human body.
Li-Fi is a revolution that will access the internet in particular in places where its use is prohibited (aircraft, hospitals, etc.) Harald Haas, Li-Fi inventor said: "We can use the wide spectrum of visible light free. It is everywhere. For example in our cars, on the streets and in our houses lit by bulbs, creating a cellular communication system more efficient than currently available. "
A first successful commercial test
In September, a li-fi prototype was installed at the headquarters of the Defence Estate Sogeprom manufacturer. It was then only a prototype, but it is now a commercial scale test has successfully met this new technology. Housed in the offices of the Estonian Velmenni start up the Li-Fi was able to reach a speed of 1 GB / s, 100 times more than the current Wi-Fi. In the laboratory, the li-fi had managed to reach a speed of 224 GB / s.
