WiFi 6 achieves these high speeds by increasing the simultaneous exchange of data within the same bandwidth on multiple devices. This technology is already in use on LTE networks. The somewhat cumbersome name MU-MIMO-OFDMA hides the following combination of functions:
MU-MIMO: Multiple user MIMO (multiple input, multiple output) improves the use of router antennas. Under WiFi-5, the router mainly transmits to the respective end device with MIMO. Wi-Fi 6 is meant to stream more evenly in both directions. This means that the router can send and receive data to multiple end devices at the same time. With WiFi 6, the maximum number of channels also increases from four to eight.
OFDMA: Orthogonal Frequency Division Multiple Access supports transmissions through MU-MIMO by using frequency spectra more effectively. For this OFDMA divides the signals within the channels more finely with many simultaneous accesses to the network. The result is a more stable and delay-free connection in high-load WLAN networks as standard, such as in airports, train stations and many shopping centers.
