A thermoelectric conditioning arrangement may comprise a first antenna/splitter configured to transmit a power & control signal, a second antenna/splitter configured to receive the power & control signal, a waveguide coupled between the first antenna/splitter and the second antenna/splitter, wherein the power & control signal is guided from the first antenna/splitter to the second antenna/splitter via the waveguide, a power converter configured to receive the power & control signal from the second antenna/splitter and generate a direct current (DC) signal, and a thermoelectric cooler (TEC) configured to receive the DC signal from the power converter.
