MU-MIMO

- [Instructor] Something else that can increase our speeds is MU-MIMO. MU-MIMO stands for multi-user, multiple input, multiple output. Basically, we're talking about having multiple antennas inside of our access points. Way back in 802.11n, we had a single spatial stream, meaning that we could transmit one stream of communication at any one time. For example, if I needed to talk to both wireless clients from this access point on screen, I would have to send the signal twice. Once to one client, and then I'll have to send it to the other client. I would have to take turns. However, with the current versions of 802.11ac and now 802.11ax, we can have multiple antennas that simultaneously transmit out to multiple clients. As an example, let's say that here we have two spatial streams, where I can simultaneously communicate from my access point to both wireless clients. That's going to give us increased throughput in…
