Differentiated and Modulated Spectrum Power Radiation Via MIMO and Beamforming Imposed Upon Ambient Electromagnetic Power Harvesting Chips

A reader apparatus, comprising:

• a processor;
• a non-transitory memory;
• a plurality of multiple input multiple output (MIMO) antennas coupled to the processor;
• and
• a reader application stored in the non-transitory memory that, when executed by the processor:
• transmit, to a first AEPH chip, a first interrogation signal via a first MIMO transmit antenna of the plurality of MIMO antennas in a first frequency band to activate the first AEPH chip;
• receive, from the first AEPH chip via a first receive antenna, a first signal in response to the first interrogation signal;
• and
• transmit, to a second AEPH chip, a second interrogation signal via a second MIMO transmit antenna of the plurality of MIMO antennas, wherein transmitting the second interrogation signal is concurrent to receiving the first signal or transmitting the first interrogation signal.

A non-transitory computer-readable medium comprising instructions, that when executed by a processor, perform the steps of:

• transmitting, to a first AEPH chip, a first interrogation signal via a first MIMO transmit antenna of a reader apparatus in a first frequency band to activate the first AEPH chip;
• receiving, from the first AEPH chip, a first signal via a first receive antenna in response to the first interrogation signal;
• and
• transmitting, to a second AEPH chip, a second interrogation signal via a second MIMO transmit antenna of the reader apparatus,
• wherein transmitting the second interrogation signal is concurrent to receiving the first signal or transmitting the first interrogation signal.
