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 commercialisation and could ease the strain on our increasingly crowded wireless networks.
Spectrum crunch is a huge problem for network operators, caused by a growing number of smartphones, laptops and other internet-enabled devices combined with a limited amount of space on the networks they’re connected to.
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.
“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.”
