1. A device, comprising:

  • a primary antenna configured to be located external to a subject,at least one processor connected for electrical communication with the primary antenna, the at least one processor configured to;

    cause transmission of a primary signal from the primary antenna to an implantable device, wherein the implantable device includes at least one pair of modulation electrodes,wherein the processor is further configured to adjust one or more characteristics of the primary signal to generate a sub-modulation control signal adapted to cause a current at the at least one pair of modulation electrodes below a neuromuscular modulation threshold when received by the implantable device and to generate a modulation control signal adapted to cause a current at the at least one pair of modulation electrodes above the neuromuscular modulation threshold when received by the implantable device.
