WiFi 7 What is 8×8 MU-MIMO? IPQ9554-IPQ9574-QCN9274
Wi-Fi technology updates have always been at the forefront of technological advancement.
wifi4-wifi5-wifi6-wifi7 are all proof of a little advancement in technology.
Everyone knows MU-MIMO in wifi technology, but what role does it play? Maybe some people don't quite understand.
What is MIMO? MIMO means that multiple independent spatial data streams can be established from the AP to the Client at the same time, and data can be transmitted at the same time. 2x2MIMO is two data streams, and 4x4MIMO is four spatial streams.

Then what is MU-MIMO, if there is no MU-MIMO, the AP can only communicate with one client at the same time, and MU-MIMO can allow different spatial streams to communicate with different clients, if the router supports 4x4MIMO, the client supports 2x2MIMO, then The router can communicate with two 2x2clients at the same time, or four 1x1clients at the same time. In order to support MU-MIMO, it is necessary to perform Sounding on the channels of different antennas. The 802.11ac protocol supports up to 4x4 MIMO, and 802.11ax supports up to 8x8 MIMO. The corresponding Sounding of 802.11ac is 4x4, and the Sounding of 802.11ax is 8x8.
And the upcoming wifi7 may use 8x8MU-MIMO or more,
8x8 MU-MIMO refers to a configuration in Multi-User Multiple-Input Multiple-Output (MU-MIMO) technology used in wireless communications. MU-MIMO technology allows multiple data streams to be transmitted and received simultaneously to increase the throughput and efficiency of wireless networks.
In traditional MIMO technology, a 2x2 or 4x4 configuration is usually used, that is, 2 or 4 antennas are used at the transmitter and receiver for data transmission and reception, respectively. The 8x8 MU-MIMO expands the number of antennas to 8, and can support data transmission of 8 user equipments at the same time.
Using 8x8 MU-MIMO technology, a wireless access point (AP) can send different data streams to multiple user devices in parallel, and the user devices can simultaneously transmit data streams back to the AP. This can significantly increase network capacity and throughput, reduce interference between user devices, and provide better network performance and user experience.
