1. A method comprising:
communicating a sounding signal to a plurality of devices through a first antenna array coupled to a basestation;
in response to the sounding signal, communicating a response signal to the basestation from each of the plurality of devices, from the response signal determining device data comprising a signal strength of the sounding signal and phase information of the sounding signal;
grouping the plurality of devices into a first group based on the device data;
generating first transmit beamforming weights for the first group to shape a power output of the first antenna array into higher power and lower power regions for communicating a data signal to the first group; and
broadcasting the data signal to the first group through a wireless signal from the first antenna array using the first transmit beamforming weights.
