1.5 MU- MIMO T e c hno lo g y
Multi-User, Multiple-Input, Multiple-Output (MU-MIMO) allows an AP to transmit
multiple groups of MU-MIMO enabled WiFi clients at the same time, using a technology called RF
multipath. MU-MIMO divides its bandwidth evenly among all MIMO-compatible WiFi clients and keeping
the WiFI signal constant for them all. Transmit Beamforming
directly to WiFi clients to effectively extend WiFi coverage and minimize dead spots. WiFi clients in the
same group can also co-ordinate in order to transmit to the AP at the same time. MU-MIMO helps
decrease client waiting time and increase network throughput. This will improve WiFi performance with
MU-MIMO compatible WiFi clients.
