In case you haven’t heard of the term yet, “LiFi” is short for Light Fidelity and refers to the modulation of light in order to wirelessly stream data. It is similar to WiFi as the modulation of radio waves, which is light at an invisible wavelength. LiFi technology is also sometimes referred to as “VisibleRead more

When I first read about LiFi (wifi where light is used instead of radio waves), I started imagining a whole new and bright future equipped with potentially hundreds of GHz of available frequency and Terabits flowing to and from my devices. The world would definitely be a much better place, with internet a thousand times fasterRead more

Martyn Wingrove discusses the next-generation light technology that offers better availability, capacity, reliability and security than wifi Wifi’s radio communications signal does not transmit well through steel decks and bulkheads. And while engineers have come up with creative workarounds, overall, improvements have been limited and costs are considerably higher than expected.

Passive and active sensors that detect low-frequency (audio) to the invisible (Radar, Lidar and Thermal) to cameras, will be central to creating autonomous vehicles that yield safer driving. Similarly, outward communications, whether via dynamic signage, audio blasts or some other means, to the humans walking, riding or driving the streets is critical for mobility machinesRead more

When industry stakeholders started considering how Li-Fi might be deployed in aircraft cabins, certain naysayers predicted that the cons would outweigh the pros, and we’d be lucky to see it roll out in our lifetime. Li-Fi leverages light to send information, in contrast to Wi-Fi, which uses radio waves. Though it has proven capable ofRead more

The Astronics stand is showing a pureLiFi system in Hamburg that could be used to quickly transfer data to and from aircraft at the gate via light. The Gatelink pureLiFi system uses light instead of radio waves to connect devices for fast data transfer. “Get Connected” first wrote about this technology back in 2016 whenRead more

aeroLiFi is demonstrating the ability of LiFi to stream video to multiple screens. LiFi uses both the visible and invisible light emitted by LEDs to transmit IFE data and an internet connection. Therefore, access points can continue working during the plane’s local night, and every LED bulb is a potential access point.

5G phones and the gigabit speeds you can hope to enjoy dominated headlines at this year’s Mobile World Congress, but another demo, the transmission of similar levels of bandwidth over visible light using modified LED bulbs, caught our eye at MWC 2019.

Users such as Singapore’s Republic Polytechnic love the speed of Li-Fi, which is starting to look genuinely faster than Wi-Fi. And then there are all the other advantages. If only the gadget and laptop makers would get behind it. MARK HALPER reports.
