The Wi-Fi technology, supposedly immune to bottleneck-causing interference, works by letting a number of distinct transmitters send same- and similar-frequency data “to multiple independent receivers without interfering with each other,” the computer scientists, led by Professor Dian Katabi from MIT’s Computer Science and Artificial Intelligence Lab (CSAIL), say in their news release.
MIMO is used commonly — when you make a cell phone call, for example. MIT's distributed MIMO system coordinates access points better, the researchers say.
It achieves the same as MIMO—which we already use in our smartphones, other mobile devices and Wi-Fi routers—but without the interference you’d normally get by using the same frequencies in the same session. Synchronizing the phases, time and frequencies by the algorithm cancels out the crashing signals.
Quark! Quark! Beware the quantum duck!
