MIT Scientists Develop New Wi-Fi That's 330% Faster (msn.com)
An anonymous reader quotes a report from MSN: Scientists at MIT claim to have created a new wireless technology that can triple Wi-Fi data speeds while also doubling the range of the signal. Dubbed MegaMIMO 2.0, the system will shortly enter commercialization and could ease the strain on our increasingly crowded wireless networks. Multiple-input-multiple-output technology, or MIMO, helps networked devices perform better by combining multiple transmitters and receivers that work simultaneously, allowing then to send and receive more than one data signal at the same time. MIT's MegaMIMO 2.0 works by allowing several routers to work in harmony, transmitting data over the same piece of spectrum. MIT claimed that during tests, MegaMIMO 2.0 was able to increase data transfer speed of four laptops connected to the same Wi-Fi network by 330 percent. Paper co-author Rahul said the technology could also be applied to mobile phone networks to solve similar congestion issues. "In today's wireless world, you can't solve spectrum crunch by throwing more transmitters at the problem, because they will all still be interfering with one another," Ezzeldin Hamed, lead author on a paper on the topic, told MIT News. "The answer is to have all those access points work with each other simultaneously to efficiently use the available spectrum."
Usually I would say %330 as fast meaning 3.3 times the speed. or 1/3 the time to transmit the same data.
Does "faster" usually mean a different thing than "as fast".
Sorry, go back to high school: “increase [...] by 330 percent” means 4.3 faster.
Rounding 3.3 to three would have been acceptable.
People should stop using variation percentages outside the range -50% – +100%, i.e. ÷2 – ×2. They always get it wrong.
And why does /. eats U+2212 MINUS SIGN?
Since they are talking about many devices connecting to multiple routers it's not going to do much for the average home user then. I may have a couple of devices but only the one router. They haven't found a new Wi-Fi but a method for coordinating the routers to handle the load as they say their method could be applied to cell stations too.
Those are two pretty fucking good reasons.
Not any time soon.
It's still going to be wired coming out of your cable/dsl modem or optical transceiver.
Someday it might be done 100% cellular but not as long as they insist on having an access charge for every device you own.
10GB of data is 10GB of data it doesn't (with current networks anyway) matter if I use it on one cell phone or 1000 IOT monitors I strapped to the trees outside to monitor their O2 production.
Minimum threshold fixed. Thanks!
My Wi-Fi is already capable of speeds much faster than what I get from my isp. I could see the need for faster Wi-Fi if I transferred tons of files from one room to another, but I don't have that need.
First give me faster internet speed; then maybe I'll need faster Wi-Fi.
I have to mention yes this was 2 years ago but I feel it's relevant). /. on how to build a network to handle google fiber without doing any modifications to the building.
Someone did a ask
https://ask.slashdot.org/story...
He was planning on using a poweline adapters and wanted to know a better solution IIRC /. pretty much just said run a wire there is not any wireless solution that could handle those speeds.
Minimum threshold fixed. Thanks!
I can run 10 Gbps on fiber over a distance of 40 km using 5 watts of power. I have zero interference and can run as many lines in parallel as I want. And this is with typical enterprise equipment---I assume the telco guys have better options.
Call me when wireless can do that. Or not, as I'll probably be running 40 Gbps (or higher) by then.

Even if their throughput claims aren't 100% bullshit...
Do you mean as much bullshit or twice as much bullshit ? I'm confused...
The numbers are easier to understand here:http://news.mit.edu/2016/solving-network-congestion-megamimo-0823
Both Owen Hughes' ibtimes article and the summary say "triple" the speed, which. should be four times the speed.
Three times faster is technically correct, but seems asinine when allowing this kind of English should allow you to say "one time faster" for twice as fast ("my new car can go one time faster than my old car").

Yes, more transceivers are better than less, thank you MIT.
But only if they're really tightly synchronized.
MIT got them to be tightly synchronized despite being in different boxes in different rooms, rather than all being in the same box, WITHOUT a lot of extra, extra-special, extra-fancy, extra-cost, hardware. This can be built with a bit more off the shelf stuff (maybe the SAME amount of the same off the shelf stuff but with a bit better firmware) and easily folded into the next generation's chips.

Want to run cable with minimum disruption to the building than eg http://www.skirtec.com.au/ . Skirting and architrave ducts. Simply pull off the empty solid ones and replace with hollow ones that can accommodate cables and outlets. Always, always go with wire where you can, everything will run much smoother. So you work in ceiling space, bring cable down at doorways to the floor and around the room you go. To get from floor to floor, drill a hole, use fixed floor to ceiling cupboards, with removable backs and bases, either new or existing ones. Prep in one weekend, cupboards, ducts et al and wire in the next.
