MegaMIMO 2.0 promises faster Wi-Fi

Researchers at MIT's Computer Science and Artificial Intelligence Lab (CSAIL) may have come up with a solution: A system called MegaMIMO 2.0, which can transfer data over Wi-Fi more than three times faster than current options, with double the range.

Researchers explained the findings in a paper released this week. The key to the MegaMIMO 2.0 system is coordinating multiple access points at the same time, on the same frequency, without creating interference.

"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, PhD student and lead author of the paper, told MIT News. "The answer is to have all those access points work with each other simultaneously to efficiently use the available spectrum."
