Methods of configuring and using a wireless communications device

Abstract

A method of controlling access to a movable container, the method comprising controllably locking the container using an electronically actuated locking mechanism; storing in a memory a desired geographical location; determining the geographical location of the container; and enabling the locking mechanism to unlock the container if the determined geographical location matches the desired geographical location. A secure cargo transportation system comprises a vehicle including an enclosure having an opening; a door movable relative to the opening between a closed position, wherein the door restricts access to the enclosure, and an open position: an electronically actuable lock configured to selectively lock or unlock the door relative to the enclosure; a memory supported by the vehicle and configured to store a location coordinate; and a global positioning system supported by the vehicle and coupled to the memory and to the lock, and configured to enable the lock to unlock the door if the vehicle is within a predetermined distance of the location coordinate.
