Wearable wireless electronic devices and methods of providing communications via wearable wireless electronic devices

A wearable first wireless electronic device, comprising:

• a user-wearable transmitter comprising:
• first and second electrodes that are spaced apart from each other and that are configured to extend around at least a majority of a circumference of a limb of a human body of a user when the user-wearable transmitter is worn by the user on the limb, the first and second electrodes being configured to transmit communications through a transmission medium provided by a human body of the user to a second wireless electronic device on or adjacent the human body of the user.

A method of providing body-coupled communications between a wearable first wireless electronic device and a second wireless electronic device, the method comprising:

• transmitting the body-coupled communications from first and second electrodes of a user-wearable transmitter of the wearable first wireless electronic device through a human body of a user to the second wireless electronic device that is on or adjacent the human body of the user, when the user-wearable transmitter is worn by the user, wherein the first and second electrodes extend around at least a majority of a circumference of a limb of the human body of the user when the user-wearable transmitter is worn by the user on the limb, and
• wherein the first and second electrodes are spaced apart from each other.
