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 an individual. The basic requirement of this technology is the available of light!

Light is also an electromagnetic wave like radio waves. The only difference is that the former has the ability to transmit data almost ten thousand times faster than latter! The basic process is quite simple to understand. An LED light bulb, any one at all, can be flicked on and off in order to be able to generate signals. A light sensor on a device picks up the digital information sent by the LED, which enables it to be processed by a computer.

The question is whether anyone wants to 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 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 move from one room to another, you will need to 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 like 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 the Wi- Fi except that it uses light waves instead of radio waves.

2. The speed generated by Li-Fi can be up to ten thousand times greater than the average Wi-Fi

3. No one wants to go through the annoying experience of sitting under a flicking light bulb.

4. It is convenient for you to use Li-Fi to transmit signals when you move to various rooms in the building.

5. The technology of Li-Fi has several of advantages in theory, but we cannot put into practice.
