In-flight internet — if and when an airline offers it — is often unreliable and slow. Oledcomm wants to take things up a notch by making high-speed LiFi available on Air France and KLM flights. The French tech company will equip a reproduction of a medium-haul plane with LiFiMAX at the International Paris Air Show. Winners ofRead more
Li-Fi stands for Light Fidelity, which is an advanced technique that utilizes the method of light communication set up of radio waves in Wi-Fi technology. It is a dual directional, well networked, and fast paced optical wireless communication technique. This technology utilizes ultraviolet rays, infrared radiation, and visible spectrum for its operation. The thought behindRead more
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
In the early days of the internet, people connected to the web via a dial-up connection. Many of us remember the days of that loud modem noise followed by a cheerily robotic voice informing us that we got mail.
Radio spectrum, the backbone of 3G, 4G, 5G, Wi-fi, bluetooth, radio and television networks and broadcasting, is getting crowded, especially in densely-populated cities like Hong Kong and Singapore.
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.
Most companies operate a wireless network as a part of their business infrastructure. They are often reliable and extend the enterprise’s scope beyond their wired network, but they are not perfect. Concerns about radio interference and security have always plagued wireless networks, so network vendors are looking to the future of wireless communications. One advancementRead more
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
The world never settles for less and how? By discovering avant-garde technologies that make our lives much at ease. Today, you can’t imagine your world without an internet connection. From booking a cab to searching the net on how to do basically anything, the internet is your sole savior! Be it your work or yourRead 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.
