Abstract
A method includes initializing transmission of multicast data with non-overlapping beamforming antennas by a wireless access point responsive to multiple clients; determining a beam pattern for transmission of the data by the access point responsive to feedback on a signal-to-noise-ratio SNR of each client under every beam pattern; and scheduling a multicast of the data to the clients responsive to the determining and to one of an optimal beam streaming configuration and a sub-optimal beam streaming configuration for partitioning the beam patterns into groups for creating composite beam patterns associated with assigned modulation coding and video streams.
