The LiFi wireless technology has been a laboratory test project in the making for long now, not until recently when an Estonian based start-up Tech Company conducted a real test outside the laboratory that saw internet data transmission speed of up to 22gb/s

LiFi technology is a wireless technology that allows for visible light transmission of internet data via flashing light at ultrahigh frequency.

Unlike your WiFi, which uses radio waves on smaller spectrum, LiFi technology as we have mentioned, uses visible light on broader spectrum, thus allowing for greater data transmission.

The test conducted shows that LiFi technology can also use the light bulb in your living room to transmit those ultrahigh frequencies internet data to your devices, thus making it appear rather more interesting.

However, the little drawback of this latest innovation is that since it is not easy for light to penetrate wall, the normal WiFi technology offers greater strength here, therefore, the LiFi technology might not offer total replacement for the WiFi and the best will be to have both technologies on ground running concurrently.

Inside the LiFi technology drawback that we just mentioned comes in it added advantage of providing better network security than WiFi.

This will be a great development.

I will comment when the Qifi and the Zifi is out.
