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 ...

Database Management in the Cloud Computing Era

Cloud Database Introduction- Cloud computing is the driving force behind many successful services, the reason being it offers businesses computing resources at scale. Database management can be an expensive and complicated operation, and many agile-minded teams aren’t satisfied with the slow progress of the database development process. That’s where cloud database management comes in. This guide outlines the basics of cloud database management and reveals how a cloud database management tool can help you achieve your desired goals. What’s Different About Cloud Database Management? Since Big Data arrived on the scene, database management has become more complicated and difficult. In addition to traditional, structured data like product intelligence and business contacts, we now have unstructured and semi-structured data, which is significantly harder to analyze. A significant amount of unstructured and semi-structured data comes from the mobile web. With more people around the world acc...
