LiFi Technology, What It is, How Does It Work

LiFi,- When we talk about internet connection, we must know the term WiFi. This is a technology that employs 2.4 GHz and 5 GHz radio bands to connect electronic devices to WLAN (Wireless Local Area Network).

Further, it is generally known that WiFi is the common technology used in offices, schools, public places, or even houses.

With this kind of network, people can connect their personal devices such as tablet, mobile phones, laptop, etc, wirelessly.

But, do you know that nowadays, there are a new technology that is predicted about to replace WiFi? This technology called LiFi. Quite strange, right?

Then, what LiFi actually is?

An Explanation to LiFi, A New Kind of Internet Networking System.

We will discuss it further in below explanation. The trend toward wireless technology is getting bigger. It is even predicted that this kind of technology could replace the wired ones in the following years ahead.

Therefore,any kinds of technology related to wireless, it must get a full attention from the world. We have introduced to WiFi technology earlier. But, the technology moves fast, created a new player in the field. Here is where LiFi came as the new kind of WiFi.

LiFi stands for Light Fidelity, a similar technology with WiFi in several aspects. Providing bidirectional and high speed transmission, this technology could deliver the communication network wirelessly.

The term LiFi was firstly introduced by Harald Haas, a teacher in University of Edinburg in Scotland. It is actually a form of communication which employs visible lights and optical wireless.

Many people say that this communication technology could be a replacement to data broadcasting, and even a complement to RF communication.

Then, how does this one works? If it is very similar to WiFi, what is their difference? The answer of these questions will be answered below.

Just like wireless technology, LiFi is a bridge between the internet devices to the internet network. But, in its operation, it uses light, the visible one. So, if in WiFi we are connected to the internet connection through the spectrum of RF (Radio Frequency), in LiFi, we will be connected through visible light.

On some cases, it also employs near-ultraviolet and infrared. This light is generated from LED (light-Emitting Diodes), and could transfer the high speed network for communication.

Therefore, Lifi is actually similar with WiFi. But, it uses LED light as a medium to deliver the connection. So, the one who can access the network is the one in the lighting range. While for the market share, this kind of networking is predicted to have a high potential in the market.

Global Li fi market size ( is estimated to grow atCAGR of almost 67% with USD 4.98 billionbillion during the forecast period 2022-2025. The “YOY (year-over-year) growth rate for 2022 is estimated at 54.11%” by the end of 2025.

An Explanation to LiFi, A New Kind of Internet Networking System

There are a lot of advantages of using LiFi networking. Mainly, this technology will be very useful in the electromagnetic sensitive area like airplane, nuclear power plant, and hospital.

It is because kind of technology is not causing electromagnetic interference. Moreover, it is also predicted that this tech will cost less than WiFi.

However, there is also some disadvantages brought by it. Even US governments already warned that this tech is so potential I causing spectrum crisis since it uses higher spectrum than WiFi itself.

Certification in Indonesia

It is generally known that every post and telecommunication devices need to be certified first before marketed in certain country. And since LiFi is obviously classified to the post telecommunication device, so it needs to be certified too.

In Indonesia, the certification institution is handled by SDPPI. As a result, based on the Indonesian regulation No. 16 Tahun 2018 about telecommunication devices certification, every communication device that still being produced, assembled, used and traded in Indonesian territory, is mandatory to have type approval certification.

Therefore, if you are manufacturer who manufactures LiFi technology, you should prepare to apply this certification before decided to market your product in Indonesia. We hope this article is useful and can be guidance for you in choosing the best technology you’re about to use.
