    MIT scientists claim to have created a new wireless technology that can triple Wi-Fi data speeds while also doubling the range of the signal. The technology basically combines multiple transmitters and receivers that work simultaneously, which allows for the sending and receiving of more than one data signal at the same time.

    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. The system is similar in size to a standard Wi-Fi router and could prove particularly useful at high-capacity events where large numbers of people are fighting for bandwidth space, such as concerts and football matches.
     
  2. This was a big "Duh" in how to improve performance. The only problem using more channels between the routers becomes tricky as those other channels are "suboptimal" in terms of signal quality.

    Increasing data transfer by 330% is more than quadruple not triple.

    if you increase bandwidth by 330%, you are at 430% the original bandwidth.

    Example in math:

    If n=100%

    50% increase in n means n + 50% of n which would be 1.5n.

    So a 330% increase in n would be n + 330% of n, or rather 4.3n. 4.3*100% = 430%.

    What's 300% of 1MB?

    3 MB. What's 1 MB increased by 300%?

    I'm 100% convinced that faster wifi is a good thing. ;)

    3x or 4x the speed is great and all, sounds good on paper, but we need more info. 802.11ac already reaches rates of 1Gbps when it is not operating alongside another 802.11ac transmitter and also uses MIMO to achieve this speed. Is this what they are comparing against? What frequency are they using? Will it achieve this speed when there's an identical network running the same hardware nearby? MIT just has to wag their finger and they get press coverage it seems.

    4Mb. But you don't count the initial 1MB as a speed increase making it 3x since 1MB was already there?

    But the article said increase. So 330% plus the initial speed.

    yes, but will it cause brain cancer

    That's only worrisome for people with brains.

    Great, even faster WiFi, how about we get some damn movement on 10GBe becoming the norm?

    And I'm sure it will work flawlessly when someone pulls out their 802.11b client connected to another AP that's on the same channel that's in use...

    I can't wait for the name of the WiFi design 10 years from now... SuperUltraAmazingMegaMIMO 9.0

    I would be more interested to know how this new wireless technology handles latency and multiple devices connected to a single source. As it currently stands the limiting factor to most AP's is the gigabit connection physically joining it to the network. What I do hope it allows for is a fast enough data throughput at a lower power output the ceiling mounted units get too hot. The new AC AP's I am installing are supposedly faster than I can physically supply them with data, so next everybody in my office is going to be complaining that even with the new AP's the speeds aren't any better because their laptops can’t read/write the data fast enough to keep up. God forbid they start expecting 3 or 4x the speed increase.

    TL;DR
    I hate fucking WiFi

    Actually that's not the case at all. For the average AP no one can actually max out a gig connection. Wifi simply isn't fast enough to do that. With 60% overhead, you'd need approx. 1.6gbps link rate to actually be able to have 1 gig in HALF duplex. There actually isn't a AP / client combo that I'm aware of that would actually do that. You'd need to have at least 2 x 2 running 160mhz channels. Or 4 x 4 at 80mhz (The more likely of the two, which you might be able to setup if you run bridge mode between two APs)

    IEEE 802.11ac - Wikipedia, the free encyclopedia

    MU-MIMO is still limited by the number of antennas on the AP side, so even with 4 antennas it's actually going to get worse performance than a dedicated 4 x 4 connection to another single AP.

    Current routers and devices routinely exceed the speed of the average users internet connection soooo for most people it would net no result.
     
  21. Didn't read the article did you?

    This is for public venues with multiple access points working together.

    my intelligence increased 100% by reading this thread, or I am going to put in 110% effort into figuring it out

    You gotta wonder though how this is going to effect the bees, bats, birds, etc.

    Nah, you'll be 'well done' before that happens.

    As long as they can do it without cooking the people in the path of the transmission signal. These are microwaves we're talking about. You can always increase the range. 'Gee, it's getting warm around here. Couldn't have anything to do with that thing up on the metal pole, do you think?'
