LOW POWER MAGNETIC FIELD BODY AREA NETWORK
First Claim
1. A body area network comprising:
- a first coil configured to be worn on a body portion of a human;
a transmitter to drive the first coil to generate a magnetic body field through the first magnetic coil;
a second coil coupled to the signal transmitted via the first coil matched to the magnetic field and first coil; and
a receiver for receiving the signal from the second coil.

Abstract
The invention provides a body area network that uses a near magnetic field for communications. A first coil is configured to be worn on a body portion of a human. A transmitter drives the first coil to generate a magnetic body field through the first magnetic coil. A second coil couples to the signal transmitted via the first coil matched to the magnetic field and first coil. A receiver for receiving the signal from the second coil. A method for establishing network communications using the human body as a magnetic field includes associating a transmitter coil with a portion of a human body, the transmitter coil being configured to couple to a receiver coil in a near field of the human body; driving the transmitter coil to generate a magnetic near field around the human body; and coupling to the magnetic near field with a receiver coil.
