1. A method of communicating in an acoustic wireless network that is spectrum-constrained and includes a plurality of nodes spaced-apart along a length of a tone transmission medium, the method comprising:
- encoding an encoded character with an encoding node of the plurality of nodes, wherein the encoding includes;
(i) selecting, based upon the encoded character and from a first predetermined lookup table, a first frequency for a first transmitted acoustic tone;
(ii) transmitting the first transmitted acoustic tone, at the first frequency, via the tone transmission medium;
(iii) selecting, based upon the encoded character and from a second predetermined lookup table, a second frequency for a second transmitted acoustic tone, wherein the second frequency is different from the first frequency; and
(iv) transmitting the second transmitted acoustic tone, at the second frequency, via the tone transmission medium; and
decoding a decoded character with a decoding node of the plurality of nodes, wherein the decoding includes;
(i) responsive to the transmitting the first transmitted acoustic tone, receiving a first received acoustic tone from the tone transmission medium;
(ii) calculating a first frequency distribution for the first received acoustic tone;
(iii) determining, from the first frequency distribution and the first predetermined lookup table, a first decoded character distribution for the decoded character;
(iv) responsive to the transmitting the second transmitted acoustic tone, receiving a second received acoustic tone from the tone transmission medium;
(v) calculating a second frequency distribution for the second received acoustic tone;
(vi) determining, from the second frequency distribution and the second predetermined lookup table, a second decoded character distribution for the decoded character; and
(vii) identifying the decoded character based, at least in part, on the first decoded character distribution and the second decoded character distribution.

Abstract
Methods of acoustically communicating and wells that utilize the methods are disclosed herein. The methods generally utilize an acoustic wireless network including a plurality of nodes spaced-apart along a length of a tone transmission medium. In some embodiments, the methods include methods of communicating when the acoustic wireless network is spectrum-constrained.
