With the popularity of the Internet, Wi-Fi has become an indispensable part of many people's lives. What's interesting is that when Wi-Fi is not available, everyone is thinking about looking for Wi-Fi, and even when Wi-Fi is connected, they often have headaches because of the long loading time.
Fortunately, researchers at the University of Technology Eindhoven in the Netherlands have come up with a breakthrough idea that uses infrared light to bring wireless data to laptops and smart phones.
According to Ton Koonen, professor of Eindhoven University of Technology, “The Wi-Fi we use today is based on radio wave technology. It is very easy to overload and interfere with. It is like a big cake. When everyone is rich, everyone is assigned to it. It will be very little.
However, the introduction of infrared light can solve this problem. By using the 'light antenna' to radiate infrared light from different angles and accurately aiming at multiple smart-enabled devices, you can enjoy fast and independent networks without sharing. Of course, infrared light is harmless to the human eye, so people don’t have to deliberately Dodge. â€
Prof. Koonen also said that their team has been studying infrared rays for many years. According to relevant experimental tests, within 2.5 meters, infrared light can transmit 42.8 Gigabits of network per second, which is 100% faster than today's Wi-Fi. Multiple times, downloading movies at this speed will also become a matter of a few seconds.
However, in addition to its high speed and insusceptibility to interference, infrared light has some shortcomings. The biggest drawback is that it has no way to pass through the wall, which means that if this technology can be realized, infrared rays need to be installed in every room. antenna.
"While this technology is not complicated, it requires more tests to be put into operation." Professor Koonen also said, "I believe that in the future, it will likely replace Wi-Fi as a new generation. wireless network."
