What is Li-Fi Technology?

Telecom startup Velmenni recently 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. 

About Li-Fi Technology:

Li-Fi, which stands for Light Fidelity, is a mobile wireless communications technology that uses light rather than radio frequencies to transmit data.
The father of this technology is Professor Harald Hass.
Li-Fi uses special LED (light-emitting diode) bulbs for the transmission of data.
It is a high-speed, bidirectional, and fully networked wireless communication of data using light.
Li-Fi technology only needs a light source with a chip to transmit an internet signal through light waves.
Li-Fi devices deliver data through visible, infrared, or ultraviolet light. 
LiFi provides internet users with wireless connections that are over 100 times faster than Wi-Fi routers because light has a larger bandwidth than radio waves. 
It has delivery speeds of up to 224 GB per second.
LiFi can be used in a variety of applications, such as internet access, phone-2-phone or phone-to-TV communications, or in emerging use cases such as extended or mixed reality.
LiFi also provides greater data security because the signal does not pass through walls, and it can be used in areas where radio frequency is undesirable, like hospitals, aeroplanes or under water.

They aim to establish social, economic, and political justice in the country and promote the welfare of the people. Although not enforceable by courts, they serve as a moral and political compass for the government. Here are some key provisions of the DPSP in the Constitution of India: 1. Promotion of Welfare: The state shall strive to promote the welfare of the people by securing and protecting, as effectively as it may, a social order in which justice, social, economic, and political, shall inform all institutions of national life (Article 38). 2.
