1. A base station, comprising:

  • a plurality of N antennas configured to transmit and receive electromagnetic signals;

    wherein the base station is configured to;

    transmit electromagnetic signals to a device through the plurality of N antennas at a power level that is above a startup threshold;

    receive an activation threshold and a saturation level of the device from the device after the base station transmits the electromagnetic signals through the N antennas at the power level above the startup threshold, wherein the startup threshold is greater than the saturation level;

    a controller, wherein the controller is configured to;

    jointly select a plurality of M of the plurality of N antennas and a transmission power level, for transmitting a wireless energy transfer (WET) signal from the base station to device based on the received activation threshold of the device and the received-saturation level of the device;

    and wherein the base station is further configured to;

    transmits the WET signal to the device at the selected transmission power level through the selected M antennas;

    receive an uplink wireless information transfer (WIT) from the device through the selected M antennas.
