LIFI (light fidelity) technology is a new way to exceed internet in save and fast, name of LiFi technology to relate with WIFI otherwise it works by VLC (visible light communication). Our world is progressing rapidly in all fields of life with help of science and technology which make our life comfortable and easy going and day by day inventing useful gadgets and devices for us.

This discussion is about the upcoming invention with great innovation that replaces harmful and expensive products to make our life more efficient and swift.

Dependence on our life on the internet is part and parcel like a human being’s life on oxygen, the internet helps us to shop, study, banking and communicate all over the world etc.

LIFI supports all types of light as visible ultraviolet and spectrum visible part. Professor Harald Hass from the University of Edinburgh invented LiFi technology he claims that LIFI is more efficient and productive than WIFI. The basic principle of LIFI is very clear and easy to understand switch of LED light on transmit data and off switch stop transmission of data.

Working principle of Li-Fi technology

However, Light Fidelity is a newly wireless introduced communication technology which permits a wireless data transmission through the LED light. Light Fidelity is established on an exclusive ability of solid-state lighting systems to construct a binary code of 1s and 0s with a LED flickering that is invisible for mortal eyes. Data can be obtained by electronic devices with photo-diode within the area of light visibility. Light hits nearly everywhere so communication can also move along with light effortlessly. It means that everywhere LEDs can work, lighting bulbs can fetch not only the light but wireless Connection simultaneously. With the growing requirement for wireless data, lack of radio spectrum and problems with harmful electromagnetic pollution, Light Fidelity seems like a new greener, healthier and economical compared to WIFI.

Benefits of LIFI Technology

  • LIFI has more benefits than another network like WIFI, LIFI is strong in strength because its medium is light that travels fast then radio waves on which WIFI depends.
  • Security mechanism is more safe and secure and have the vast range with less cost than WIFI, LIFI doesn’t cross the wall so data can’t be theft.
  • LIFI is an environment-friendly without any side effect on living objects. It has no electromagnetic smog like WIFI, data transmitting capacity is on a prodigious level which no any other network has.
  • Furthermore, availability of LIFI network is more reliable and have massive and enormous scale. Presence all over the world like underwater, airplane and radioactive areas where radio waves cannot approach.
  • LIFI consumes less energy than other networks so it is cost effective.

Weakness of LIFI Technology

  • LIFI depends upon LED inner light but sunlight can create problems in its working and connectivity.
  • High installation can be expansive through LIFI due to increasing electricity charges etc.
  • LED must be in straight in line for data transmitting. But that is a challenged to keep lines straight for better data transmitting.
  • The coverage area is limited, LIFI cannot cross walls.

Latest research on LiFi Technology

According to upcoming news, scientist engages in creating a micro-sized (LED) to make every bulb LIFI hotspot and cars headlights which make easily data transmitting.

LIFI is a healthy step toward a new generation, it can fulfill all fast activities without any harm. In this world where science is progressing day by day and producing multiple things some are good and bad that is us choose, we need peace, health, and comfort in our lives. So, we should adopt the healthy things in our life like, LIFI which is healthy and environment-friendly.
