BrandPost: What’s the Difference between OFDMA and MU-MIMO in 11ax?

The IEEE’s latest standard, 802.11ax, has been designed inside and out for high efficiency. Also known as Wi-Fi 6, 11ax promises real-world performance improvements that will keep today’s mobile users and IoT devices connected and happy. To achieve that, over 50 features have been proposed as part of the 11ax standard. Once adopted into the standard, they will be rolled out to the market in phases – Wave 1 and Wave 2, just like with 802.11ac.

Multi-user Multiple-Input, Multiple-Output (MU-MIMO) and Orthogonal Frequency-Division Multiple Access (OFDMA) are two of the most significant technical enhancements in 11ax. Both MU-MIMO and OFDMA are multiuser technologies that enable simultaneous bidirectional communication between an access point (AP) and end users. So how are they different?
