MEGAMIMO 2.O : 10X FASTER THAN WI-FI : Technology Shows : - Nigeria's Premier Online Forum

Wireless interference is one of those things that we tend to not think about, because, well, we can’t see it. But routers are all over the place, sometimes several in a room when you’re in an office, conference, or campus and make no mistake, it’s an epic battle at the frequencies they share.
MIMO stands for multiple-input multiple-output.
“Multiple-input multiple-output” essentially means it can use several transmitters and receivers at the same time.The new system, called MegaMIMO 2.0, can transfer wireless data more than three times faster than the Wi-Fi we use today, and it also doubles the range of the signal.
Developed by a team from MIT’s Computer Science and Artificial Intelligence Lab (CSAIL), MegaMIMO 2.0 could one day be implemented in the Wi-Fi routers we use at home, if device manufacturers like Cisco and Netgear end up incorporating the system into their products.
But the biggest advantages of the new technology would be seen in more crowded environments like sporting events, convention centres, or airports where hundreds or thousands of people are all trying to connect to the same internet signal.
As many of us have experienced, in public venues like these, the speed of the network can turn glacial, and that’s a result of what those in the industry call ‘spectrum crunch’  where there simply isn’t enough wireless spectrum available for everybody to get their data quickly.
One of the ways of avoiding spectrum crunch is to add more wireless access points  in the form of multiple routers  for Wi-Fi users to connect their devices to. But this fix only goes so far, as each new access point creates a level of interference on the network that can also slow down data transfer.
The technique works because radio waves will bounce off surfaces and therefore arrive at the receivers at slightly different times. Any network that can use multiple receivers can combine streams to transmit data much faster.
To test the new system, the researchers set up a mock conference room, with four laptops travelling around the room on Roomba vacuums, and measured data speeds as they went. They found that MegaMIMO 2.0 boosted data transfers 330 percent when compared to conventional Wi-Fi.
There’s no word yet on when we’ll see this new system in action, but the researchers are in the process of commercialising the technology, and say they’re in talks with industry partners to bring MegaMIMO 2.0 to the market.
