Abstract:
The invention provides a body area network. A first coil is configured to be worn on a body portion of a human, and the first coil is configured and positioned to use a body leveraged magnetic field. A transmitter drives the first coil to generate a magnetic body field through the first magnetic coil at a frequency selected such that the body leveraged magnetic field simultaneously includes near-field and far-field components and the far-field components are enhanced by a high dielectric constant of bodily tissue. A second coil couples to the signal transmitted via the first coil, and the second coil is configured and positioned to receive both of the near- and far-field components. A receiver receives the signal from the second coil. A method for establishing network communications using the human body as a magnetic field drives a transmitter coil to generate magnetic near- and far-field components that include the human body as a medium to propagate the magnetic near- and far-field components, wherein the driving is at a frequency and transmission power selected to enhance far-field magnetic flux density via guiding at a boundary of the human body.
