Antenna-parameter control in a distributed system

A non-transitory computer-readable storage medium for use in conjunction with an electronic device, the computer-readable storage medium storing program instructions that, when executed by the electronic device, provides modified electrical signals by causing the electronic device to perform one or more operations comprising:

• providing, via an interface circuit in the electronic device, electrical signals intended for an antenna module, wherein the electrical signals correspond to an output transmit-power level at the interface circuit;
• receiving, via the interface circuit, feedback from the antenna module about an input transmit-power level at the antenna module and an orientation of an antenna in the antenna module;
• determining a modified output transmit-power level based on the input transmit-power level at the antenna module and the orientation;
• and
• providing, via the interface circuit, the modified electrical signals intended for the antenna module, wherein the modified electrical signals correspond to the modified output transmit-power level at the interface circuit.

A method for providing modified electrical signals, comprising:

• by an electronic device:
• providing, via an interface circuit in the electronic device, electrical signals intended for an antenna module, wherein the electrical signals correspond to an output transmit-power level at the interface circuit;
• receiving, via the interface circuit, feedback from the antenna module about an input transmit-power level at the antenna module and an orientation of an antenna in the antenna module;
• determining the modified output transmit-power level based on the input transmit-power level at the antenna module and the orientation;
• and
• providing, via the interface circuit and based on the feedback, the modified electrical signals intended for the antenna module, wherein the modified electrical signals correspond to a modified output transmit-power level at the interface circuit.
