What is LiFi

LiFi, a new revolution in the wireless connectivity is an abbreviation of Light Fidelity. It is also a wireless technology used to transmit the data. But it is different from WiFi. WiFi uses radio waves to transmit Data but LiFi uses Light Signals. LiFi relies on special LED bulbs which transfer the data by using changes in light Intensity. The speed of LiFi is far more than WiFi.

How Does LiFi Work?

Imagine a world where light becomes data. Wi-Fi is simple but powerful; we all know how a lightbulb works. When an electrical current is applied to an LED light bulb, a constant stream of light is emitted, which we see as illumination. Since LED bulbs are electronic devices, the current and light can be modulated at extremely high speeds. This can be detected by a photo detector and converted back to electrical current, carrying data. This is the nervous system of an internet revolution.

Wi-Fi doesn’t replace your internet service provider. You’ll still need them to get the Internet to your home or office via wires. However, once you have that high-speed connection, you can deploy your fast, secure Wi-Fi network using power over ethernet or power line communications.

Wi-Fi offers greater density than many other radiofrequency solutions. For example, if you have an average Wi-Fi router in your office that provides up to 100 megabits per second and 15 people are connected to that router, it means that you might only be able to access a few megabits per second. However, with a Li-Fi network of lights that offer 42 megabits per light, even if you had only eight lights in your room, those same 15 people could share more than 300 megabits per second. That’s dense and fast wireless communication.

Li-Fi is also bi-directional, full-duplex, and high-speed. Data is transmitted and received at the same time, resulting in a really fast and reliable user experience, especially when doing things like Skype calls, video streaming, and virtual reality. Li-Fi is fully networked, meaning all the lights in your Li-Fi network can speak to each other and handover as you move around the space. Each light even has its own IP address, which means that you can offer location tracking and geofencing within your network.

Welcome to a world with unprecedented data and bandwidth. Be part of the light revolution.

Li-Fi vs Wi-Fi

If we compare, LiFi is 100 times faster than WiFi and that’s amazing.

Wi-Fi may soon face a strong contender in the form of Li-Fi, a technology that uses light instead of radio waves to provide wireless connectivity.

Sharing WiFi password can cause you security risks, See How

The Institute of Electrical and Electronics Engineers (IEEE) standards body has introduced the IEEE 802.11bb light communication standard for Li-Fi, which promises speeds up to 100 times faster than Wi-Fi.

Li-Fi has many advantages such as reduced interference, higher security, and the ability to easily integrate into existing light fixtures.

Companies like Signify and pureLiFi have made strides in this space with data beaming bulbs and light antenna one systems, respectively.

The Light Antenna One claims speeds of over 1Gbps and offers widespread Li-Fi adoption.

With download speeds reaching 224Gbps, Li-Fi has the potential to outperform Wi-Fi 7. As Li-Fi continues to advance, it could soon become a transformative technology in the realm of wireless connectivity.

In a historic move that marks Pakistan’s debut in lunar exploration, the country’s first satellite mission named ICube Qamar was successfully launched aboard China’s Chang’e 6 mission from Hainan, China. This monumental event not only underscores the burgeoning space alliance between Pakistan and China but also signifies a pivotal moment in global lunar research efforts.

The Chang’e 6 mission, renowned for its ambitious goal to retrieve samples from the far side of the moon, took to the skies on a Long March-5 rocket from the Wenchang Space Launch Site. This mission is poised to carve a new chapter in lunar exploration by focusing on areas of the moon that have remained largely unexplored by previous missions.

Exploring the Moon’s Mysterious Far Side

China’s venture to explore the enigmatic far side of the moon showcases the nation’s advancing capabilities in space technology. The Chang’e 6 mission is designed to spend two days on the lunar surface, with plans to gather around 2 kilograms (4.4 lb) of lunar samples. These samples are anticipated to shed light on the moon’s composition and uncover secrets about its enigmatic past.

What sets this mission apart is its emphasis on collaboration. The integration of Pakistan’s ICube Qamar satellite into the mission exemplifies a global collaborative effort in the quest for lunar exploration. ICube Qamar, representing Pakistan’s inaugural venture into moon exploration, is poised to play an instrumental role in gathering data from the lunar surface, enhancing our collective understanding of the moon.

A Milestone of Collaboration

The mission’s successful launch has been greeted with widespread acclaim and enthusiasm, especially within Pakistan, where the Prime Minister has celebrated this achievement as a landmark moment for the country’s aspirations in space exploration. This event underscores the profound partnership between Pakistan and China in pushing the frontiers of space technology and exploration.

The Chang’e 6 mission, featuring payloads from various countries, serves as a testament to the spirit of international cooperation that fuels our exploration of the cosmos. Through shared resources, knowledge, and visions, nations are unlocking extraordinary possibilities in space exploration, paving the way to unravel the mysteries of our universe collectively.
