Classification: CPC H | IPC H

Claim 0:
1. A device comprising:
a first set of analog beamformers (ABFs);
a first control communication interface that provides communication between individual ones of the first set of ABFs and a control system;
a first set of digital beamformers (DBFs), wherein individual ones of the first set of DBFs receive signal data from one or more of the first set of ABFs;
a second control communication interface that provides communication between the individual ones of the first set of DBFs and the control system; and
the control system comprising one or more processors executing instructions to:
determine first data indicative of a first set of beam directions;
determine a first beam direction based on the first data;
determine a first set of beam coefficients based on the first beam direction, wherein individual beam coefficients in the first set of beam coefficients are associated with operation of respective ones of the first set of ABFs;
send, using the first control communication interface, the first set of beam coefficients to the first set of ABFs at a first cadence;
operate the first set of ABFs using the first set of beam coefficients;
determine, for a second beam direction of the first set of beam directions, a second set of beam coefficients, wherein individual beam coefficients of the second set of beam coefficients are associated with operation of respective ones of the first set of DBFs;
send, using the second control communication interface, the second set of beam coefficients to the first set of DBFs at a second cadence, wherein the second cadence is faster than the first cadence; and
operate the first set of DBFs using the second set of beam coefficients.
