1. A communication apparatus, comprising:
a first antenna array comprising a plurality of antenna elements;
a first plurality of thermoelectric devices distributed across the plurality of antenna elements of the first antenna array, wherein each thermoelectric device of the first plurality of thermoelectric devices covers a different subset of antenna elements of the first plurality of antenna elements;
a processor coupled to the first antenna array and the first plurality of thermoelectric devices, wherein the processor is configured to:
determine a performance state of the plurality of antenna elements based on wireless communication by the first antenna array, and wherein the determined performance state comprises at least one of: a performance drop, a gain drop, a connectivity drop, a voice drop, a power output drop associated with the first antenna array;
detect an operational state of each antenna element of the plurality of antenna elements of the first antenna array;
execute an activation or a deactivation of each thermoelectric device of the first plurality of thermoelectric devices in a real-time or near real-time based on the detected operational state and the determined performance state, wherein the activation or the deactivation is performed in a defined delayed time after a defined time has elapsed from a start of operation of the first antenna array to mitigate performance degradation of the plurality of antenna elements when in operation; and
control adaptive cooling applied by each thermoelectric device of the first plurality of thermoelectric devices on different subsets of antenna elements of the first antenna array by adjusting a voltage input to each thermoelectric device of the first plurality of thermoelectric devices such that performance breakdowns due to heating of a plurality of chips associated with the different subsets of antenna elements is reduced.
