First Claim
1. A computer-implemented method, in an access point having MU-MIMO capability, for automatically grouping stations into groups to optimize Wi-Fi beamforming transmissions over a communication network, the method comprising the steps of:
- associating with stations of a plurality of stations over a Wi-Fi portion of the communication network, wherein the stations have MU-MIMO capability;
determining a mobility profile for each station of the plurality of stations, the mobility profile including factors that characterize at least an amount of movement and current location for a station;
assigning each station to a beamforming group, each station of the beamforming group having similar mobility profiles;
selecting a type of beamforming transmission for each beamforming group based on mobility profiles of associated stations, the type of beamforming transmissions including at least MU-MIMO and SU-MIMO; and
transmitting data to the stations of each beamforming group according to the selected type of beamforming transmissions.

Abstract
An access point associated on Wi-Fi portion of the communication network selectively groups stations according to a mobility profile. The mobility profile includes factors that characterize at least an amount of movement and current location for a station. Each station is assigned to a beamforming group of similar mobility profiles. A type of beamforming transmission is selected for each beamforming group based on mobility profiles of associated stations. The type of beamforming transmissions including at least MU-MIMO and SU-MIMO. Data is then transmitted to the stations of each beamforming group according to the selected type of beamforming transmissions. A Wi-Fi controller, having a network-wide view of conditions and being able to collect historical information about stations during connections to other access points, is able to provide data unique data to group selections.
