JNCASR Adds More Security To LiFi



With a maximum data transfer rate of 1 Gbps for long-distance transmission, the LiFi HotSpot provides a suitable replacement alternative to WLAN networks and cable connections. "By combining WISeKey's Secure Element (our tamper-resistant silicon chip) and our managed Public Key Infrastructure (PKI) systems with Oledcomm's experience in Li-Fi development and technology, we are bringing powerful solutions to companies that wish to implement the Li-Fi technology and increase the level of security for their IoT ecosystems," said Carlos Moreno, Vice President Corporate Alliances & Partnerships at WISeKey.

As we now know, Li-Fi is a Visible Light Communications (VLC) system. The signal is then converted back into a binary data stream that we would recognise as web, video and audio applications that run on internet enables devices. The inventor of Li-Fi, Professor Harald Hass, Co-founder of pureLiFi and Chair of Mobile Communications at UK's University of Edinburgh, refers Li-Fi as light based communications technology.

In Li-Fi the information is transferred through light signals instead of radio waves and mostly Wi-Fi plays an efficient role for wireless information coverage within the buildings whereas by using Li-Fi we can provide the excel density data coverage in a particular area without any radio interference issue.

In order to send data over light, Li-Fi relies on LED bulbs. I can see it being used in streetlights as access points for smart city applications,” he says. It uses the visible spectrum rather than radio waves. The partnership with pureLiFi was a good fit due to the modular nature of the company's LED light bars.

Li-Fi networks avoid radio frequency interference, an increasingly important consideration in homes as the popularity of Internet of Things (IoT) and other wireless gadgets continues to increase. Thus, LED bulbs in our home and office will work as a router just by placing a transmitter modulator.

LED bulbs are semiconductor devices, which means that the brightness of the light flowing through them can be changed at extremely high speeds. Well, today we will talk about the concept LI-FI or LIFI, a concept that will give much to talk about, the new era of wireless connections, an alternative to the well-known Wi-Fi.

Since light is the method of communication, anything that blocks light will block the Li-Fi signal. A startup company called Velmenni is currently working on lifi technology. Each user estimates its own location by measuring the delay time between the transmitted and received pings from each LiFi access point and calculating its distance from each fixture.

These benefits make LiFi an ideal technology to compliment 5G wireless communications. Visible light communications can offer wireless network access and indoor positioning for robots, drones and other electronic devices in warehouses and factories. I) By using shop display lighting as a Li-Fi broadcast channel, it is possible to transmit advertising information on the goods being viewed, as well as say special offers and coupons.

That's the goal of the man who invented such a technology, Visible Light Communications and this week Li-Fi took a step out of the domain of science fiction and into the realm of the real when it was shown to deliver speeds 100 times faster than current Wi-Fi technology in actual tests.

Li-Fi refers to a new wireless form of Visible Light Communication (VLC) technology which delivers bidirectional, high-speed, networked mobile communications by using light from light-emitting diodes (LEDs). Wi-Fi, or Wireless Fidelity, uses electro-magnetic waves at radio frequencies to transmit data by way of a Wi-Fi router.
