What Is LiFi? Everything You Need to Know

Undoubtedly, today’s world is completely a tech-oriented place where an individual is fully dependent on technology for his or her every single task.


Here we are going to discuss one latest technology which is currently in trend i.e. LiFi- Light Fidelity.

In this article, you are going to get every single detail about this new technology. Just have a look:

What Is LiFi?

Well, LiFi is the answer to our digital future. Basically, it is a wireless optical networking technology that makes the use of light-emitting diodes or Led rather than radio frequencies in order to transmit the data. It is the next generation of wireless technology or one can also say that it is a VLC (Visible Light Communications) system which runs wireless communications that travel at very high speed.

Pros of LiFi:

As compared to

  • WiFi, LiFi is faster.
  • Ten thousand times the frequency spectrum of radio.
  • LiFi is more secure as here data cannot be interpreted without a clear line of sight.
  • LiFi is unimpeded by radio interference.
  • LiFi also prevents piggybacking.
  • LiFi does not create any kind of interference in sensitive electronics which makes it better for use in environments such as hospitals and aircraft.
  • It eliminates neighboring network interference.
  • As compared to the single WiFi router, this new technology could enable a greater area of coverage.

Disadvantages of Li-Fi

Apart from several benefits, there are some drawbacks of Li-Fi such as:

  • It doesn’t work in dim areas.
  • It requires LOS (line of sight), as well as the receiver, would not move inside.
  • Another drawback of this technology is the interference of other light sources such as normal bulbs; sun rays in the area of communication which causes intermission in the transmission.

Li-Fi Technology Applications

  • Transportations
  • In dangerous Environments or In Sensitive regions
  • Industrial Areas
  • Traffic Management & Road Safety
  • Underwater Communications
  • Medical Applications
  • Aviation
  • Elegant Lighting
  • Interior map-reading system for blind people


Why Is LiFi Important?

At present, the wireless network has become one of the essential commodities in our daily life. There is no doubt that Wi-Fi is everywhere but unfortunately, we cannot use it forever.

Eventually, Wi-Fi will not be able to fulfill the demand of data and the world needs to future-proof our networks to satisfy the connectivity demands of tomorrow. With LiFi, we can utilize spectrum more than a thousand times greater as compared to the entire range used for radio frequencies. LiFi allows a significantly large number of access points as of WiFi’s radio frequencies(RF), achieving the higher data rates essential due to the ability to produce small cells required for faster connectivity.

LiFi - Final Verdict

According to the latest research, traditional WiFi will be massively ineffective when there are so many devices interacting in one territory. The networking ability to integrate with mobile is ultimate a WOW in LiFi, one that is characterized by the speed of data transfer and the continuous miniaturization process.

It is not the replacement of WiFi technology however, it is an incredible companion for it.
