Technology for managing beamformed signals. A method includes: receiving beamformed signals from one or more arrays of receiving elements, which one or more arrays of receiving elements send beamformed signals at given transmission rates; recovering information from the received beamformed signals; measuring a quality of the recovered information, using a metric that estimates a distance between the recovered information and reference information; and, based on the measured quality, instructing the one or more arrays of receiving elements to change the transmission rates at which they send beamformed signals.
