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."
