WEARABLE PERSONAL AREA DATA NETWORK

摘要

A near-field communications network enables a body-wearable personal area network. The near-field communications takes place in the magnetic near-field. A master node with an orthogonal antenna array controls the network. The orthogonal antenna array is orientable to maximize signal strength. The antennas are designed and operated so as to strand the energy of transmission of communications in the near-field. This reduces the detectability of the communications outside the immediate area of the near-field network.
