1. A method for communicating with an ingestible capsule, comprising:

  • selecting a first and a second carrier frequency that are associated with a first and a second frequency channel, respectively, based on a hopping pattern;

    acoustically transmitting, by the ingestible capsule, a first portion of data through a body of an animal as, an original waveform in accordance with the first carrier frequency for a duration of the first frequency channel; and

    switching, by the ingestible capsule, from the first carrier frequency to the second carrier frequency before a reflection of the original waveform is received by a receiver that is communicatively coupled to the ingestible capsule.
