Telecom startup Velmenni has received a grant from the ministry of defence (MoD) under the Innovations for Defence Excellence (iDEX) initiative for its innovative Li-Fi (Light Fidelity) technology.

LiFi (light fidelity) is a bidirectional wireless system that transmits data via LED or infrared light.

It was first unveiled in 2011 and, unlike wifi, which uses radio frequency, LiFi technology only needs a light source with a chip to transmit an internet signal through light waves.

What is advantage over today’s wireless network?

1. This is an extraordinary advance over today's wireless networks. LiFi multiplies the speed and bandwidth of wifi, 3G and 4G.
2. The latter have a limited capacity and become saturated when the number of users surfing increases, causing them to crash, reducing speeds and even interrupting the connection.
3. With LiFi, however, its band frequency of 200,000 GHz, versus the maximum 5 GHz of the wifi, is 100 times faster and can transmit much more information per second.

THIS IS HOW LIFI TECHNOLOGY WILL CHANGE OUR LIVES:
