TESTING OUT THE THEORY
NOVEMBER 2015 Of course, all that is in theory. To make sense of all this, we ran a test ourselves with the aforementioned Linksys EA8500, an AC2600 router that supports MU-MIMO. Also with us are two Acer Aspire E14 notebooks, one of the earliest adopters of MU-MIMO among notebooks. We plugged in a USB flash drive containing 4GB worth of video files to the router, and first copied it from the drive to one of the notebooks. The process took two minutes and 14 seconds, with data transfer averaging at 31MB/s.
We then repeated the test, this time with both notebooks. Transfer speeds took a dip here, going down to an average of 23MB/s, with the file transfer completed in three minutes. We would attribute the drop in speed to processing bottlenecks on the router's end because of one
With MU-MIMO, devices are each taking one spatial stream of data, meaning there is less wait time caused by the turn-taking of multiple devices sharing all spatial streams.
