Photographing people in 3D through walls using Wi-Fi

photos thru walls 3d 1

Wi-Fi can pass through walls.

This fact is easy to take for granted, yet it’s the reason we can surf the web using a wireless router located in another room. But not all of that microwave radiation makes it to (or from) our phones, tablets, and laptops. Routers scatter and bounce their signal off objects, illuminating our homes and offices like invisible light bulbs.

Now, German scientists have found a way to exploit this property to take holograms, or 3D photographs, of objects inside a room — from outside it.

A New Type of Li-Fi Has Reportedly Cracked 40 Gbps, 100 Times Faster Than the Best Wi-Fi

If you’re frustrated with slow wi-fi, you might be one of the many people eagerly awaiting the commercialisation of li-fi (or light-based wi-fi), which promises to be up to 100 times faster than the connections we use today.

Most li-fi systems rely on transmitting data via LED bulbs, which means there are some limitations to how easily the technology could be applied to systems outside the lab. But researchers have come up with a new type of li-fi that uses infrared light instead, and it’s reportedly already cracked 40 gigabits per second (gbps) in early testing.

How solar powered drones are about to transform your life

 George Bye at the DaVinci Institute’s “Night with a Futurist” talking about the future of solar powered UAVs

George Bye is the founder of Bye Aerospace, a Colorado company involved in the design of a unique solar-electric powered aircraft that use solar electric energy, stored in batteries, to drive a propeller to both fly and stay aloft for long periods of time. A special combination of technologies and design will enable the current small UAVs to maintain station, with flight endurance of 8 to 12 hours at a time – several multiples of typical aviation gasoline fuel engine UAVs. A more extreme version of this capability will be engineered into Bye’s future aircraft (both civil and defense).

Free hotspots are widespread in South Africa.

2014 is the “watershed year” for Wi-Fi, according to Ruckus Wireless. The company predicted the number of hotspots across the world would increase to 5.8 million by next year, an increase of 350 per cent from the number in 2011. (Video)

Battery-free WiFi devices that run on radio waves

battery-free-devices

What if devices could pull enough power wirelessly from the air to run themselves and send signals?

Mobile devices have become radically smaller and more powerful in the past 10 year. The list of tech-related tasks that the mobile devices we all carry around has grown longer by the year. The next step in technology’s great disappearing act? Absorption into our clothes, body, and environment.

Smartphones with larger screens use 44% more data

Smartphones with larger screens use more data.

Your WiFi and data consumption will probably be higher if your smartphone has a large screen compared to a device with a smaller screen. In fact, monthly WiFi and cellular data consumption on smartphones with screens 4.5 inches and larger is 44 percent greater than it is on smartphones with screens under 4.5 inches, at about 7.2GB and 5.0GB respectively.

Creating Spectrum for the Internet of Things

The wireless industry is against super WIFI networks while Google and Microsoft say it would spark innovation.

On February 3, 2013, the Washington Post boldly led a front-page story last weekend with the claim: “The federal government wants to create super WiFi networks across the nation, so powerful and broad in reach that consumers could use them to make calls or surf the Internet without paying a cellphone bill every month.”
