Li-Fi: New Way of Wireless Connectivity

By admin - Sep 08 ,2021

What is Li-Fi Technology?

Li-Fi (Light Fidelity), which is expected to replace Wi-Fi technology in the future, is a wireless connection technology that uses LED bulbs and visible lighting devices to transfer data and communicate wirelessly between devices. It aims to present data using light waves instead of the radio signals used by Wi-Fi. Since Wi-Fi technology, which has been used for years, is now insufficient in many places, we can say that the heart of the technology is now beating for Li-Fi, which is called a “revolution in wireless connection.” It is a system, also known as Visible Light Communication. This technology uses light because it is easier to focus signals in one place. In this way, there will be a faster data transfer situation.

How does Li-Fi work?

In Li-Fi technology, LED bulbs that illuminate our environment will also provide us with wireless internet access. This aims to act as a data transfer provider, with LEDs turning on and off at speeds that our eyes cannot perceive. The devices will have Li-Fi receivers and the information from the LEDs will be processed bilaterally. In other words, the devices will both receive information from the flashing of the LEDs and send information to the LED bulbs themselves. For this, LED bulbs will not be the ones we currently use in homes or workplaces, they will be bulbs developed to support this technology. Likewise, we will need to use Li-Fi compatible devices in devices such as mobile phones, laptops and tablets that we currently use in our homes and workplaces.

Data flow in Li-Fi technology:

If the light source of this technology is turned off, the data flow is automatically interrupted. Therefore, the lighting systems must be constantly on for data transfer to continue. For this, it is necessary to put a stable LED bulb in each room. Li-Fi uses visible light instead of radio signals. For this wireless connection technology to work properly, it is necessary to have a photodetector that receives the light and hardware that can process the signal and make the data transmittable.

As a result, looking at the comparisons between WiFi and LiFi, now it would be very difficult to choose one over the other as both have their advantages and disadvantages. Therefore, a different mindset should be adopted and these pieces of technology should be looked at differently. In the future, we will see together whether Li-Fi is a disruptive technology and whether it will completely replace wifi.
