Abstract
The present invention discloses a system that implements data communications through a barrier composed of composite, layered materials. A low frequency electromagnetic signal is used to achieve acceptable channel losses as the signal passes through a composite barrier which may comprise materials with variable conductivity and/or permeability.
Claims32
A through barrier communications system suitable for data communications through a barrier such as a freight container comprising:
- at least one of a primary coil and primary coupling core;
- and
- at least one of a secondary coil and secondary coupling core for forming a magnetic flux circuit, wherein said at least one of primary and secondary coil passes electromagnetic signals with acceptable losses from one side of a barrier to another by means of low frequency electromagnetic signals and said composite barrier comprises at least one electrically conductive layer and at least one electrically insulating layer.
A through barrier communication system according to of 24, wherein said data network is any one of GSM, Bluetooth®, Zig Bee®, GPS, RFID, or a combination thereof.
