Wipro’s Li-Fi solution could slake the thirst of bandwidth-devouring Indians

Published

on

Wi-Fi 6 is here and it’s great
No individual device on your wireless network may run that much faster, but your total speed will increase.

Imagine your entire family of digital addicts nestled in their various cocoons, watching movies at 1,000-times the speed you are accustomed to now, seamlessly and without interference. At this speed, everyone is able to stream 30 movies at the same time in 1080 HD. Needless to say, quite possibly for the first time in your life, you are a superhero.

This is the reality that Wipro and a Scottish company called Purelifi is bringing to your home. Wipro may be famous because of its IT arm, but it also has a large and well-reputed lighting division and an FMCG wing. (Azim Premji, former chariman of Wipro — he just handed over the reins to his son — used to sell vegetable oil before he transformed his company into an IT giant.)

Purelifi has successfully run a pilot project at Kyle Academy secondary school in Ayr, Scotland as part of Scotland’s digital strategy mapping. Other pilots have taken place at mobile phone company O2 and the Devonport Dockyard in Plymouth in conjunction with the Royal Navy. In fact, Prof. Harald Haas, founder and chief scientist of Purelifi, and also a professor of mobile communications at Edinburgh University coined the word Li-Fi so it’s a good bet that they know their onions.

Suddenly, in a bandwidth choked world, Li-Fi’s data dense technology can be tantalising. Its one pre-requisite — light — is everywhere. Li-Fi uses infra-red, ultra-violet as well as visible light to send data zooming about flawlessly whereas Wi-Fi is dependent on radio frequencies to piggyback on which can be prone to corruption and signal interference. Purelifi’s solution uses an Ethernet cable attached to a router and then connected to an access point, which in turn is wired to a Wi-Fi-enabled LED light.

LED lights are basically semiconductors so by adjusting brightness levels at speeds invisible to the human eye, Li-Fi can ramp up download speeds up to a scorching 1078Mbps. You plug a dongle with a transmitter and receiver into your laptop or tablet and presto, you’re in business. The dongle sends and receives data from and to the light.

Li-Fi isn’t perfect. Its signals can’t permeate walls. Its range is ultra short — 10 metres or less. And it needs light, although Purelifi says it can function when a room appears to be dark at 60 lux. Yet these concerns are mere trifles when you consider the incredible potential that Li-Fi brings when daisy-chaining a series of lights to its technology, especially in a place like India where a humongous number of users are yet to come online and where network speeds and interruptions are chronic headaches.

Purelifi’s solution has always been to stress Li-Fi’s supporting role — not competitive — in alleviating bandwidth problems. You still need some kind of pipe to get your connection to you — but from there on it is lightning fast and eminently dependable, eliminating the familiar network congestions. Its potential in the educational and medical fields, which rely on tons of videos or data heavy scans, can be immense.

But there’s also a more pivotal role for Li-Fi. Its data dense nature makes it highly capable of aiding the new digital era and specific areas of it such as augmented reality, virtual reality, machine learning, and artificial intelligence. Smart cities can use it to power a whole host of machines from just its street lamps.

Li-Fi could also save your life. Since it doesn’t leak radio signals or have interference issues, it can be used in practically any kind of environment from hospitals to nuclear plants to aircraft making it the fastest, most reliable way to access information.

Still we will never know the possibilities or potential unless Wipro makes this an affordable and well-marketed solutions package, so the jury is still out on its transformative powers.

Today’s Wordle Answer #472 – October 4, 2022 Solution And Hints

Published

on

The answer to today’s Wordle puzzle (#472 – October 4, 2022) is bough, which is what you call a branch, especially the main branch, of a tree. The word bough has roots (no pun intended) in the Old English word “bōg,” which means shoulder, similar to Old High German’s “buog,” which means the same thing (via Etymonline). There’s a popular Roman myth about the Golden Bough, which is a tree branch with golden leaves that enabled the trojan hero Aeneas to travel safely through the land of the dead. 

We solved the puzzle in three tries today, kicking things off with an expert-endorsed starter word, slate. We tried the word brush next, which turned out to be a really lucky guess with three green tiles. The answer was apparent by the third guess, and since we also solved the puzzle in three guesses yesterday, that begins a three-try streak that we hope we can continue tomorrow!

How To Display iPhone 14 Pro’s Dynamic Island On Any Android Device

You can also choose whether to display the cutout at the center of the display (for hole-punch cameras on the center of the display) or on the left for cameras placed in the corner. Remember that as you increase or decrease the cutout size, the icons shown in it will also scale to match. Thankfully, the app gives you a preview of the cutout when you are changing the settings.

You can also modify gestures such as single tap or long press. Dynamic Spot also allows you to change the default time, after which the pop-up automatically disappears. Additionally, you can fiddle with a lot of appearance-related settings, such as the animation when the Dynamic Island clone pops up or unfolds.

Just as on the iPhone 14 Pro, the Dynamic Spot on your Android app will show the app icon when a new notification arrives. You may selectively choose which apps display the notifications or allow all apps of them. You can also tap on the app’s icon to open the notification or long-press the icon to preview the notification.

The 10 Wildest Features Of The Mercedes Maybach Off-Roader

Published

on

Sustainability is a word on every car manufacturer’s radar right now, with more focus being given to the idea of eco-friendly vehicles than ever before. The Off-Roader plays into that theme by featuring a prominent set of solar panels mounted on its hood, which could be used to generate power to extend the range of the car. It’s worth pointing out that this is all hypothetical, as the show car is non-functional, and has no drivetrain. Mercedes is keen to stress, though, that if the car did have a drivetrain, it would be all-electric, although no detail is given on the power or range that would be available to drivers.

The solar panels are interwoven with yet more Maybach logos, and their tinted finish makes them blend in almost seamlessly with the rest of the hood. It’s been pointed out by industry analysts that adding solar panels to cars is not always as environmentally friendly as it might seem, as the panels are only able to generate a very small amount of power. That power can easily be consumed by the added A/C strain caused by parking a car out in the sun all day to charge it. Car-mounted solar panels might be a flawed idea in practice, but even so, it’s interesting to see how Abloh was able to inconspicuously add them in without compromising the overall look of the car.
