A method for automatically adding a first sensor device to a first personal area network in a healthcare application includes receiving a signal with out-of-band pairing data at the first sensor device. The first sensor device is disposed on a patients body. The out-of-band pairing data is injected into the patients body by a second sensor device disposed on the patients body. Pairing data is extracted from the received signal at the first sensor device. Using the pairing data, the first sensor device is added to the first personal area.
