Li-Fi Technology - The future of Wireless Technology

 What is Li-Fi ?

LiFi( light fidelity) is a wireless technology  which carry the key to solving challenges faced by 5G. LiFi can transmit at multiple gigabits, it is more reliable, virtually interference free and uniquely more secure compared to radio technology like Wi-Fi or cellular. 

LiFi is a mobile wireless technology that makes use of light rather than radio frequencies to transmit data. The technology is upheld by a global ecosystem of companies driving the adoption of LiFi, the next generation of wireless that is ready for seamless integration into the 5G core.

 

How is works ?

Radio frequency communication requires radio circuits, antennas and complex receivers, whereas LiFi is much easier and uses direct modulation systems similar to those used in low-cost infrared communications devices such as remote control units. LED light bulbs have high intensities and therefore can achieve very wide ranging  data rates.


 Benefits :

  • Speed and Bandwidth - The light spectrum is many times wider than the radio spectrum, which increases the volume of data it can carry and transmit it per second .
  • Reliability - Lifi transmits its signal without any interruptions, which make communication more stable than Wifi.
  • Cheaper - It is upto 10 times cheaper than wifi, is more sustainable, uses less energy.
  • Wireless - It takes advantage of light and dispenses with router, so it successfully works without the use of cables.

Pegasus Spyware: Flying Through The Air

 Hundreds of millions of people can't imagine life without their smartphones. Almost every aspect of their daily lives, from the most mundane to the most intimate, is within easy reach and hearing distance of their smartphones. Only few people realize that their phones may be used as surveillance devices, with someone hundreds of miles away secretly extracting their messages, photographs, and location while also activating their microphone and recording them in real time. Such capabilities are present in Pegasus, a spyware produced by NSO Group, an Israeli maker of mass surveillance weapons. What is Pegasus? Pegasus is a hacking software – or spyware – that is developed, marketed and licensed to governments around the world by the Israeli company NSO Group. It has the capability to infect billions of phones using either iOS or Android operating systems. The spyware is named after Pegasus, the white winged horse from Greek mythology. It is named so because it "flies through the...

Unhackable Internet

  W hy it matters?   The internet is increasingly vulnerable to hacking; a quantum one would be unhackable. Quantum Computing    A quantum internet could be used to send unhackable messages, improve the accuracy of GPS, and enable cloud-based quantum computing. For more than twenty years, dreams of creating such a the quantum network have remained out of reach in large part because of the difficulty to send quantum signals across large distances without loss.   Now, Harvard and MIT researchers have found a way to correct for signal loss with a prototype quantum node that can catch, store and entangle bits of quantum information. The research is the missing link towards a practical quantum internet and a major step forward in the development of long-distance quantum networks.   The U.S Department of Energy (DoE) explains how a quantum link will make it happen through two quantum phenomenon: the first is quantum entanglement, where two-particle ...

3D LASER SCANNING

  What is 3D Scanning? 3D Laser Scanning is a non-contact, non-destructive technology that uses a line of laser light to digitally capture the shape of physical objects. 3D laser scanners generate "point clouds" of data from an object's surface. In other words, 3D laser scanning is a method of capturing the exact size and shape of a physical object into the computer world as a digital 3-dimensional representation. 3D laser scanners capture free-form shapes and measure fine details to quickly generate highly accurate point clouds. 3D laser scanning is ideal for the measurement and inspection of contoured surfaces and complex geometries that require massive amounts of data for accurate description and where using traditional measurement methods or a touch probe is impractical.process :3D Laser Scanning Data Acquisition. CLASSIFICATION 1. No Contact Scanning: Millions of points on the xyz coordinate system can be easily captured via non-contact scanning. This data prov...
