1. A method for beamforming comprising:
selecting a cluster of M feeds from feeds for a coverage area comprising service areas and data streams for each of the service areas;
generating M feed excitations by distributing N data streams per M×N weights;
switching an array to transfer a respective one of the M feed excitations to a respective one of the M feeds; and
beamforming, with the M feeds of an antenna, N beams,
wherein M and N are integers greater than 0,
the N beams are each focused on a respective service area of each of the N data streams,
the M×N weights improve transmitting into the respective service area of each of the N data streams, and
at least one of the N beams comprises a portion of a plurality of the M feed excitations.
