Claim 14:
15. A wearable device, comprising:
a transmitter comprising a power detector;
one or more processors; and
one or more nonvolatile memory devices storing computer-readable instructions, that, when implemented, cause the one or more processors to perform operations, the operations comprising:
obtaining power response data for the power detector, the power response data providing a relationship between power detector readings from the power detector and measured transmit power of the transmitter;
identifying a target power detector reading value corresponding to a target transmit power based at least in part on the power response data by:
accessing the power response data to determine a target power detector reading associated with the target transmit power in a first channel;
obtaining a channel correction factor based at least in part on a characterization of power detector reading with respect to frequency; and
applying the channel correction factor to the target power detector reading to correct the target power detector reading to a second channel, the second channel being different from the first channel;

initializing a transmitter gain of the transmitter to an initial transmitter gain value;
obtaining a power detector reading value from the power detector;
determining, by the computing system, that a difference between the power detector reading value and the target power detector reading value is greater than a tolerance margin; and
adjusting a transmitter gain value of the transmitter in a direction of the difference between the power detector reading value and the target power detector reading value.
