By twisting radio waves into a threaded vortex, an international team of researchers has beamed data through the air at 2.5 terabits per second, creating what has to be the fastest wireless network ever created. Moreover, the technique used to create this effect has no real theoretical ceiling, ExtremeTech reports.

In late 2010, Verizon rolled out its 4G LTE network, which offers data speeds 10 times as fast as 3G networks. But as mobile data traffic continues to grow—experts anticipate that it will increase 26-fold in the next three years—it's unlikely that any network will be able to keep up. Fortunately, something else is set to happen over the next three years: Wi-Fi could become as ubiquitous and easy to access as cellular is now.
A couple years ago we saw wireless technology that would allow us to see through walls. Now, the same team of researchers, from the University of Utah, is putting that motion detection technology to work monitoring breathing patterns. So not only can the network see through your bedroom wall, it can hear you breathing.
Commanding an army of drones is one thing; letting drones command themselves is something else entirely, especially when they have very little in common. Boeing recently tested a swarm network to help disparate drones work together, sending two types of unmanned aerial vehicles on a reconnaissance mission over eastern Oregon.
Lawmakers in Nevada made a pretty forward-thinking move a couple weeks ago when they passed a measure ordering new regulations for driverless cars. Many vehicles already participate in once-human-driven activities like parking and skid control, and it’s not long until they’ll be able to navigate, make decisions and drive totally by themselves.
A new ultra-wideband antenna printed on paper or plastic can harvest ambient energy, enabling wireless sensors to tap into electromagnetic currents in the air around them. The device captures energy from a wide spectrum of frequencies, converts it to direct current, and stores it in capacitors or batteries.
Radio communications devices can either send or receive wireless signals at a given moment, but they can’t do both at the same time (hence the regular use of the word “over” to signal the end of a transmission). But a team of electrical engineering grad students and professors at Stanford has done what researchers have long thought impossible by developing a new antenna setup that allows wireless signals to be sent and received at the same time.
