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.

WhatsApp, which is trending these days, has brought another new feature to the field. This feature will be for those who are fond of voice messages.
The latest beta version brings interesting improvements to voice group chats, making them more user-friendly and interactive.

According to the details of WaBetaInfo, WhatsApp Beta for Android version 2.24.25.22 is based on the features of the previous version 2.23.24.20, with a focus on better accessibility and user interface.

One notable change in the latest beta update is that a floating action button has been added next to the Send message button. You can now start a voice chat within a group.

The new design will make this process more visible to all group members.

WhatsApp’s latest beta update introduces a handy new feature that makes starting voice chats more intuitive. Now, in a group conversation, you can start a voice chat by simply swiping up. Once the gesture is complete, the voice chat begins, making it easier to connect and engage with others.

The update also expands the availability of voice chats, allowing even small groups or just two people to use the feature. To keep things clean, WhatsApp will automatically close any group that remains inactive or disconnected for 60 minutes. But don’t worry—if a voice chat is already underway, participants can still notify others to join the conversation at any time.

It’s important to note that these features are not yet officially available for public use, and they may take several weeks to roll out.

Elon Musk’s SpaceX and Trump: A Bold Alliance for the Future of Space Travel

On Tuesday, the world’s attention was divided between Earth and space. SpaceX’s monumental Starship test launch — heralded as a step toward humanity’s Martian dreams — became an unexpected stage for political theatrics, as President-elect Donald Trump joined SpaceX CEO Elon Musk at the Texas launch site.

While the Starship test showcased unprecedented engineering feats, it was the burgeoning camaraderie between Trump and Musk that stole the spotlight. This improbable duo, united by ambition and outsized personas, reflects a convergence of politics, innovation, and power that could redefine American space exploration and governance.

A Billionaire and a President on the Launchpad

Trump, known for his flair for grand spectacles, arrived in Texas to witness the historic launch of SpaceX’s Starship — the largest rocket ever built. Musk, ever the visionary, explained the rocket’s intricate details, from its massive Super Heavy booster to its ambitious goals of moon landings and Mars colonization. For Trump, this wasn’t just another event. It was a calculated move to align himself with Musk’s genius and SpaceX’s success, both of which resonate with young, tech-savvy voters.

The Starship’s liftoff was awe-inspiring, yet its most anticipated moment — the booster’s dramatic return to the launchpad — ended in an anticlimactic splashdown in the Gulf of Mexico. SpaceX engineers, prioritizing safety, aborted the attempt at the last second. Despite this, the mission achieved critical milestones, including relighting its Raptor engine in orbit and a successful spacecraft splashdown in the Indian Ocean.

Trump’s “Rocket Man” Persona Takes Off

Trump’s association with Musk taps into a new demographic — young, male voters drawn to Musk’s iconoclastic persona. Appearances with Musk add credibility to Trump’s rhetoric of innovation and disruption. The dynamic was on full display at the launch, where Trump’s trademark hyperbole blended seamlessly with Musk’s scientific optimism.

With SpaceX dominating the space industry and Tesla revolutionizing electric vehicles, Musk embodies the success Trump often claims for himself. Their relationship serves mutual interests: Trump gains access to Musk’s tech-driven fanbase, while Musk secures influence in Washington.

The Intersection of Innovation and Politics

This newfound friendship, however, raises questions about conflicts of interest. Musk’s SpaceX holds lucrative contracts with NASA and the Defense Department, while Tesla remains under federal scrutiny for safety and regulatory concerns. Trump’s plans to dismantle government inefficiencies, possibly spearheaded by Musk, could tilt regulatory landscapes to favor Musk’s ventures.

Critics argue that this alliance might prioritize private gain over public interest. Trump’s history of overlooking ethical boundaries only fuels these concerns, as Musk’s growing influence risks consolidating immense power in one individual.

A Rocketship to the Moon—or a Collision Course?

While their partnership is flourishing, the egos of Trump and Musk could eventually clash. Both are used to being the center of attention, and their relationship might not withstand competing ambitions. Yet for now, their collaboration symbolizes a merging of technological ambition and political power.

As SpaceX pushes the boundaries of what’s possible and Trump prepares for his second term, this alliance could herald a new era of American dominance in space. Whether this partnership thrives or falters, one thing is clear: Musk and Trump are reshaping the conversation around innovation, leadership, and the future of space exploration.
