Claim Text:
1. An apparatus, comprising: a data source, implemented at least in part using a first hardware, configured to provide a plurality of different data streams for transmission over a same time-frequency interval; a precoder, implemented at least in part using a second hardware, configured to precode the plurality of different data streams for transmission over the same time-frequency interval by antennas of a massive MIMO antenna array; and a dynamic equivalent isotropically radiated power (EIRP) constraint calculator configured to determine an EIRP constraint for one of the plurality of different data streams and provide the EIRP constraint to the precoder, wherein the dynamic EIRP constraint calculator is configured to determine the EIRP constraint based on a distance between the antennas and a location in which a living being will potentially be impacted by a beam radiated by the antennas carrying the one of the plurality of different data streams, and wherein the precoder is further configured to adjust a width of the beam based on the EIRP constraint by increasing or decreasing a number of the antennas used to radiate the beam.
