Tissue conduction communication between devices

A method comprising:

• generating a tissue conduction communication (TCC) carrier signal;
• generating at least one TCC beacon signal by modulating a first property of the TCC carrier signal according to a first type of modulation;
• and
• generating a TCC data signal subsequent to the TCC beacon signal by modulating a second property of the TCC carrier signal different than the first property according to a second type of modulation different than the first type of modulation.

A device comprising:

• a housing;
• and
• a TCC signal detector enclosed by the housing and configured to:
• detect a TCC beacon signal transmitted from a transmitting device by detecting a first type of modulation of a first property of a TCC carrier signal;
• and
• detect a TCC data signal transmitted by the transmitting device subsequent to the TCC beacon signal by detecting a second type of modulation of a second property of the TCC carrier signal different than the first property, the second type of modulation different than the first type of modulation.
