Wi-Fi Network Breakes Speed Record

By -

    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.

Quantum Dot Technology On Its Way to Smartphones, Tablets and TVs

     Just when you thought display technology could hardly get any better, along come quantum dots, making screens more colorful while consuming less power This is not just some pie-in-the-sky dream of scientists and geeks. Nanosys and 3M have put this  Star Trek -like tech to work, and it's gone way beyond the experimental stage, to where it's now almost ready to be built into smartphones, tablets and TVs. The two companies said in a  press release  they'll have samples available to manufacturers by the "late second quarter of this year," which means companies interested in using this technology in their screens might be getting their hands on it within five weeks or so.

Samsung developing 5G technology, hopes to hit 1 gigabit speeds by 2020

Samsung developing 5G technology, hopes to hit 1 gigabit speeds by 2020 Samsung, one of the mobile industry’s biggest players in network and infrastructure, has revealed that it has started work in developing 5G data technology. While a standard for “5G” doesn’t exactly exist, we would naturally expect it to be a vast evolution from what we know to be 4G right now. Even though  4G didn’t quite start off as 4G , the standards were tweaked to allow carriers to claim as much. Indeed, the speeds we get now far surpass what 3G afforded us, giving us double digit downstream numbers (in megabits) compared to the single digits 3G (HSPA+ not withstanding) was capable of. We can’t even imagine what the next plateau for mobile data speeds will be, but Samsung believes it can deliver throughput speeds of up to 1 gigabit per second to a device by the end of the year 2020, with a single sub-station able to handle 10 gigabits of bandwidth. We’re not sure if said numbers would hold up a...

Facebook to introduce emoticon reactions

Nothing is as famous a reaction like the "like"  👍 button of facebook  According to  Engadget ES   post from Thursday  facebook to add new range of reactions emoji. this update rolls out first for spain and Ireland as testing phase, the reactions set created by engadget does not include thumbs down as reaction, my guessing is thumbs down alone doesn't justify much to a reaction instead there's an angry, sad face in the list.         This should prove to be a major update on how people express empathy.
