Legacy Wi-Fi networks are often designed for coverage, not density. In Wave 2, 802.11ac adds multi-user MIMO to help these overburdened networks. The schools’ access points (APs) were based on legacy standards, 802.11n and 802.11g. Raulston was reluctant to upgrade because he didn’t feel that the benefits of the next step up, 802.11ac Wave 1, were compelling enough to justify the expense.

802.11ac Wave 1 supports only SU-MIMO, that is, an AP can communicate with only one user at a time. 802.11ac Wave 2 supports MU-MIMO, that is, an AP can concurrently communicate with multiple users. MU-MIMO increases the number of access STAs, meeting requirements for the access of a large number of STAs in the all Wi-Fi and Internet of Things (IoT) era when one user has multiple STAs.

IEEE 802.11ac is a wireless networking standard in the 802.11 set of protocols (which is part of the Wi-Fi networking family), providing high-throughput wireless local area networks (WLANs) on the 5 GHz band.The standard was developed in the IEEE Standards Association from 2008 (PAR approved 2008-09-26) through 2013 and published in December 2013 (ANSI approved 2013-12-11).
