Li-Fi Technology
Li-Fi technology is a new technology that transmits signals as light instead of radio waves. In urban areas where Wi-Fi networks become congested and there is a lot of noise in the signals, this technology is something that can be of immense use to tướng an individual. The basic requirement of this technology is the available of light!
Light is also an electromagnetic wave lượt thích radio waves. The only difference is that the former has the ability to tướng transmit data almost ten thousand times faster than vãn latter! The basic process is quite simple to tướng understand. An LED light bulb, any one at all, can be flicked on and off in order to tướng be able to tướng generate signals. A light sensor on a device picks up the digital information sent by the LED, which enables it to tướng be processed by a computer.
The question is whether anyone wants to tướng go through the annoying experience of sitting under a flickering light bulb. This is the interesting part. The technology is focusing on make sure that the light bulb is flickered up to tướng billions of times a second! At that rate, the human eye simply cannot notice the light bulb being flicked on and off.
However, everything comes with a disadvantage. The major disadvantage here is the fact that these signals cannot penetrate walls. So if you want to tướng move from one room to tướng another, you will need to tướng have a wired bulb present in that room as well.
An Estonian startup company called Velmenni took the technology out of the laboratories and brought it into the real-world offices, and industrial environments in Tallinn for the first time.
Overall, this sounds lượt thích quite a development in the field of communication technology.
Read the passage, and then decide whether the statements are true (T) or false (F)
1. Li-Fi is similar to tướng the Wi- Fi except that it uses light waves instead of radio waves.
2. The tốc độ generated by Li-Fi can be up to tướng ten thousand times greater than vãn the average Wi-Fi
3. No one wants to tướng go through the annoying experience of sitting under a flicking light bulb.
4. It is convenient for you to tướng use Li-Fi to tướng transmit signals when you move to tướng various rooms in the building.
5. The technology of Li-Fi has several of advantages in theory, but we cannot put into practice.
