Keyhole communication device for tracking and monitoring shipping container and contents thereof
A shipping container that facilitates communications between wireless communication devices within the shipping container and an external network includes a keyhole communication device that is adapted for wireless communications with the external network and that includes first and second housing components. The first and second housing components together form an integrated housing structure that extends through a small opening in a wall of the shipping container, with the first housing component being disposed exterior to the shipping container and the second housing component being disposed interior to the shipping container. A first antenna is disposed within the first housing component for communications via a first communications protocol, such as a Bluetooth protocol. A second antenna also may be disposed within the first housing component for communications via a second communications protocol, such as a cellular communications protocol. The communications are controlled by electronic circuitry within the second housing component.

10. The method of claim 1 , wherein the first and second housing components include correspondingly threaded fittings that are adapted to be screwed together for securing of the first housing component and the second housing component together in said step (d).
11. The method of claim 1 , wherein first electrical contacts located on the first housing component and second electrical contacts located on the second housing component are electrically connected to one another when the first housing component and the second housing component are secured together in said step (d).
12. A method of attaching a communication device to a shipping container, comprising the steps of:
(a) providing a communication device, that includes a first housing component and a second housing component, and that further includes electronics and at least one antenna configured to enable the communication device to wirelessly communicate both with a network that is external to the shipping container and with one or more wireless devices contained within an interior of the shipping container;
(b) mounting the first housing component on an exterior wall of a shipping container such that the first housing component is disposed substantially exterior to the shipping container; and
(c) mounting the second housing component on an interior wall of the shipping container such that the second housing component is disposed substantially interior to the shipping container;
(d) wherein the first housing component defines a first hollow interior, the second housing component defines a second hollow interior, and the first housing component and the second housing component fonn an integrated housing structure with the first hollow interior being contiguous with the second hollow interior.
13. The method of claim 12 , wherein the first and second housing components are mounted to the wall by securing the first and second housing components together through an opening in the wall of the shipping container.
