Wi-Fi Network Breaks Speed Record

Think your network is fast? Getting a gigagbyte-sized movie over your local wireless network to your hard drive in a few seconds is old hat. Now there’s a network that can push a 2-hour, high-definition movie to a computer a mile away in less time than it takes to read a single word. At the Karlsruhe Institute of Technology in Germany, a new record has been set: 40GB per second over a distance of about .6 of a mile. That’s like sending 10 high-def feature films What makes this possible is a combination of better hardware and the use of higher radio frequencies, in this case, 240 gigahertz. That hardware is a set of chips developed at Karlsruhe that can process signals at higher frequencies. Higher frequencies mean smaller components, since a shorter wavelength can be picked up by a smaller antenna (which is why FM and AM radios need relatively large antennas, while Wi-Fi receivers can use small ones). These chips were only a few millimeters on a side. Read more…More about Wi Fi, Tech, Gadgets, Mobile, and Speed Record
