Project Skybender: Google's secretive 5G internet drone tests revealed | Technology | T... - 0 views

  • Google is testing solar-powered drones at Spaceport America in New Mexico to explore ways to deliver high-speed internet from the air
  • Project SkyBender is using drones to experiment with millimetre-wave radio transmissions, one of the technologies that could underpin next generation 5G wireless internet access
  • High frequency millimetre waves can theoretically transmit gigabits of data every second, up to 40 times more than today’s 4G LTE systems. Google ultimately envisages thousands of high altitude “self-flying aircraft” delivering internet access around the world.

  • “The huge advantage of millimetre wave is access to new spectrum because the existing cellphone spectrum is overcrowded. It’s packed and there’s nowhere else to go,” says Jacques Rudell
  • However, millimetre wave transmissions have a much shorter range than mobile phone signals. A broadcast at 28GHz, the frequency Google is testing at Spaceport America, would fade out in around a tenth the distance of a 4G phone signal. To get millimetre wave working from a high-flying drone, Google needs to experiment with focused transmissions from a so-called phased array. “This is very difficult, very complex and burns a lot of power,” Rudell says
  • The SkyBender system is being tested with an “optionally piloted” aircraft called Centaur as well as solar-powered drones made by Google Titan, a division formed when Google acquired New Mexico startup Titan Aerospace in 2014. Titan built high-altitude solar-powered drones with wingspans of up to 50 metres
  • Project SkyBender is part of the little-known Google Access team, which also includes Project Loon, a plan to deliver wireless internet using unpowered balloons floating through the stratosphere.
  • In 2014, Darpa, the research arm of the US military, announced a program called Mobile Hotspots to make a fleet of drones that could provide one gigabit per second communications for troops operating in remote areas.

Research Says Screen Time Can Be Good For Your Kids - Forbes - 0 views

  • Still, most parenting wisdom continues to portray television as an evil mind-rotting demon. The fear of ‘screen time’ is so deeply ingrained in our collective imagination that an irrational opposition between outdoor play and media consumption is taken for granted. Many parents believe the choice is either/or: indoors or out.
  • most storytelling is interactive. We consume most of our media through internet connected devices. And technology is so adept at providing ‘adaptive feedback’ that it proves to be an exceptionally effective teaching tool. In fact, a recent SRI study shows that game based learning can boost cognitive learning for students sitting on the median by 12%.
  • Joint media engagement refers to spontaneous and designed experiences of people using media together, and can happen anywhere and at any time when there are multiple people interacting together with digital and traditional media.

  • Restrictive Mediation
  • Unlimited access to media becomes one of the markers of adulthood.
  • Instructive Mediation describes what happens when we talk to our kids while watching a movie or playing a video game with them. Make it a teaching opportunity
  • Instructive mediation is key for raising kids that are critical thinkers and intelligent adults in a media saturated world–kids who know how to THINK about the media they consume.
  • Social Coviewing is when you watch something with your kids but don’t necessarily talk about it. This is what happens in a movie theater.
  • This is what happens when I watch Phineas and Ferb with my kids.
  • Parallel play is kind of like multitasking. I can be typing on my Chromebook next to my son while he’s playing minecraft. We engage in peripheral conversations, some tangential, and some directly related to the game he is playing.
  • Asymmetrical joint media engagement
  • While interacting with me online, I hope they learn good web etiquette. I’m teaching them lessons about propriety and social media. They see the kinds of things I write in emails and chats.

I quantified my baby and wish I could get the time back - 1 views

  • It’s part of an experiment to see if technology can help with the daunting and seemingly Sisyphean tasks of a first time parent, to find out why a growing number of people are turning to gadgets to help with one of life's toughest jobs.
  • Attempting to simplify parenthood with gizmos and apps has perversely made it a lot more complicated. And as for peace of mind, forget it.
  • The concept of the “quantified baby” has been around for some time now, and there’s a large and growing market for smart infant products from anxious or diligent or curious new parents.

  • But does it all help you to be a better father, or mother, or is it all a massive distraction from the serious business of parenting?
  • While tracking proved useful as a reminder of feedings, and gave an objective insight into longer term sleep patterns, there wasn’t much she could do with the info.
  • It's the same problem quantified self devotees have: what to do with all that data. Unless you're a math or data viz wizard and prepared to take it all incredibly seriously, the numbers that consumer gadgets and apps spew out can be pretty meaningless — even more so when you're dealing with an unpredictable baby.

Netherlands Has First Nationwide Internet of Things Network | Digital Trends - 0 views

  • Netherlands first to establish nationwide Internet of Things network
  • Three initial projects give a sense of the scope and types of application that will make up the Internet of Things. At the port of Rotterdam, depth sounders have already been outfitted with sensors and network connections. An experiment at Utrecht will connect all railway switches so they can be monitored centrally. And at the Schiphol airport in Amsterdam, a major European hub busier than JFK and Miami International combined, tests with baggage handling are already underway. If you think of the number of pieces of luggage moving through the worlds sixth-busiest international airport you begin to get a sense of the scale of applications for IoT. If each piece of luggage has an IoT tag, nothing should be unaccounted for.

BBC - Future - Is e-waste an untapped treasure? - 0 views

  • Electronic waste, or e-waste, is a rapidly growing global problem
  • Yet many are realising that the gadgets we chuck away can be ripped apart and transformed into something new – brand new technology, or even art.
  • In 2012, we discarded 48.9 million tonnes of electrical and electronic products. If current trends continue, by 2017, the annual amount of e-waste produced globally will reach 65.4 million tonnes – that’s roughly 20% of the weight of all the people living on Earth.

  • Using parts and wires from old computers, scanners and photocopiers (some of it for free, but most bought), and an Arduino electronics card as the brain, they managed to put together a working prototype for a few hundred euros (see below).
  • “In Togo, there are many people who can’t have access to computers, because they don’t have money to buy a new computer,” says Allahare. “But we have many computers that are broken and not working. It’s sometimes just a little piece that is spoiled in it. W.Jies can help people get connected, get information, and help kids learn ICT from low-cost computers.”

    in 2012 china alone produced 11.1 mlm tones of e-waste, what can be considered trash in one part of the world, can indeed become a treasure in the other part of the world

  • UK government invests £60 million in Skylon 'super-plane' that could cut London to Sydney flights to just four hours
  • Its 'Sabre' engine - a hybrid rocket and jet propulsion system which theoretically allows travel anywhere on Earth in four hours or less - could become a reality in a decade.
  • A full ground-based engine test is currently planned for 2020.
