Radio Tornadoes Could Deliver Never-Ending Wi-Fi Capacity Some Day

Coaxial wiring — like what runs into your cable box — revolutionised data transmission by drastically widening the wire’s data pipeline. Two years ago, a research team from University of Southern California accomplished the feat using a vortex of lasers. Now, that same team is back with a means of coiling radio waves around themselves that could provide us with theoretically limitless, long-range Wi-Fi connectivity.


How To Make Sure No One's Secretly Stealing Your Home Wi-Fi

Wireless Network Watcher is a free, simple program for Windows XP and above that can take a quick look at the computers and devices connected to your home network.

The iPhone's Wi-Fi Handoffs Make Internet Calling Better Than Ever

You’ll be able to call people using your Wi-Fi connection on the iPhone 6, so when your Wi-Fi is working better than your reception is (all the time?) you’ll have an alternative.

Future Wearables Could Communicate Using Reflected Wi-Fi

Sending data between small, portable devices is full of compromise: higher transfer rates usually means a bigger drain on the battery. But UCLA researchers have a plan to use reflected Wi-Fi signals to help solve that problem.


How Your Hotel Room Price And Wi-Fi Speed Are Linked

Ever wondered if you’re paying for the bed linen or the Wi-Fi? The network-analysing super-wonks at OpenSignal have crunched through some data about public Wi-Fi, and analysed in detail the network performance in different hotel rooms. Here’s how your room price and download speed are linked.


Roving Robots Can Look Through Buildings Using Nothing But Wi-Fi

Previously, we’ve seen researchers use everyday Wi-Fi signals like radar, able to detect shapes through a door or wall. Well, here’s the logical next step toward the robot overthrow: Putting that tech on top of wheeled robots. You can run (OK, walk), but hiding behind a brick wall is futile.


Belkin AC 1750 DB Wi-Fi Modem Router: Australian Review
