1. A guided surface wave receive node, comprising:
- a guided surface wave receive structure configured to obtain electrical energy from a guided surface wave traveling along a terrestrial medium, the guided surface wave being generated by a guided surface waveguide probe, the guided surface wave comprising an embedded message;
an electrical load coupled to the guided surface wave receive structure, the electrical load being experienced as a load at an excitation source coupled to the guided surface waveguide probe; and
a communications transceiver configured to establish a communications channel via a different message mechanism from the embedded message.
