Wireless near field communication system

摘要

A wireless magnetic field communication system working within the range of less than 1.5 m without induction induced interference during listening mode is proposed. The system comprises at least a transmitter and a receiver. Several novel transmitter designs using either active-connection-control solenoid or spin-orbit torque (SOT) based patterned thin film element(s) are proposed. The system has intrinsic high data security level due to its limited working range, as well as large data transfer rate. The system is suitable to establish a temporary off-the grid magnetic field communication network. It also provides a new data communication approach among modules instead of data cable in industry equipment. The system can be used as a standalone or built-in system for communication between devices or modularized components of a system.

主权项

1. A wireless communication system comprises at least:
a solenoid coil, each turn of which links to a switch controlled by a common control-switch, acting as a transmitter and being capable of broadcasting information-coded magnetic field in the space around it; A receiver capable of sensing the magnetic field; Electronics for controlling or/and driving said transmitter and said receiver.
