"As for how the it all works, researchers devised a system called MegaMIMO whereby WiFi signals are not “sent over the same frequency at the same time.”
MegaMIMO 2.0 is a distributed MIMO system that coordinates the activity of access points (wireless routers, for example) so that signals are not sent over the same frequency at the same time. Eliminating interference permits all of the transmitters in an area to operate more efficiently.
MegaMIMO 2.0 was tested with a setup composed of four independent transmitters and receivers located in the same area. With a traditional point-to-point MIMO system each of these uncoordinated transmitters would operate at about one quarter efficiency because they would interfere with each other. By coordinating the four transmitters, MegaMIMO 2.0 increased data throughput by a factor of 3.6. Because interference scales up with the number of transmitters in an area, eliminating interference with MegaMIMO 2.0 is expected to produce greater performance gains as the number of transmitters increases.
