Even if you've never heard of Li-Fi, you can now know what it is. Li-Fi (Light Fidelity) is a new Wi-Fi technology, it is realized mainly through the visible spectrum for wireless data transmission. This exciting technology first appeared in in a speech Professor Harold Hass of 2011.
This year Spain MWC Mobile World Congress in Barcelona, PureLi-Fi company gives us Li-Fi of the actual product, so what it have to do with Wi-Fi different? to find out.
PureLi-Fi network chief operating officer at Harald Burchardt when in an interview said: "Li-Fi works is very simple, we communications wireless signal by LED lamps, it is somewhat similar to Wi-Fi, however we are using LED lamps and other lighting medium to complete the wireless data communications. "
It is understood that Professor Harold Hass from 2003 began to study this Li-Fi technique, as he foresaw the looming spectrum crisis. At about the same time, new LED lighting technology begin to hit the market, and Professor Harold Hass came up with idea of bringing them together. Eventually, he found a way to use these electronic lighting set up to achieve high-speed data transmission method, and without disrupting the existing infrastructure of radio frequencies.
PureLi-Fi founded in 2012 the company's main objective is to commercialize the technology of Li-Fi. And they show the actual product is a u-shaped adapter, top is equipped to receive light signals light and infrared camera receiver. In addition, stand above or compatible Li-Fi settings for wireless data transmission LED lights and the transmitter.
According to Digital Trends reports, this product at the MWC Conference data transfer speeds of up to 40Mbps, and in the case of light reflection to achieve strong stability, light edges will decline, thanks to the reflective light equipment there is no problem with the connection, walking does not affect use.
Harald Burchardt noted that has two key advantages of the Li-Fi technology, which can transmit more data within a local area, and security is higher. He explained: "in the Li-Fi environment, the total capacity of the data will be promoted, coupled with the light cannot pass through the wall, therefore, compared to Wi-Fi, we create networks will have a higher degree of security. "
In addition, Harald Burchardt said: "as the technology matures, ideally we want this product is reduced in size, will make it a integrated circuit module, and then used in smartphones, tablets, laptops, wearable devices and other types of electronic devices. " Ted Baker iPhone 6 covers
However, Harald Burchardt finally admits that the technology is promising, then it also needs 10-15 to appear in each LED lights or on every piece of electronic equipment, and PureLi-Fi the company you want to do is in a relatively short period of time to achieve this goal.
