Abstract

A remote intelligent communications device includes a primary RF communications port and an alternative modem communications port. The remote intelligent communications device receives configuration data for configuring the alternative modem communications port. The remote intelligent communications device obtains information data concerning a select attribute of an associated object. The information data is stored within internal memory of the remote intelligent communications device. Thereafter, the stored information data is retrieved, per one embodiment via the alternative modem port, from the remote intelligent communications device and analyzed for drawing conclusions regarding the select attribute of the associated object. Preferably, the remote intelligent communications device also includes a navigation (e.g. GPS) receiver that obtains navigation data, which navigation data is also stored within the internal memory of the remote intelligent communications device. By storing this navigation data together with the information data, once the stored data is retrieved from the remote intelligent communications device, the information data and navigation data can be analyzed for correlating the select attribute of the associated object with respective geographic position in accordance with the analyzed information and navigation data. In one exemplary application, the specific attribute is an open/close condition of a door of a cargo bay, monitored by an appropriate transducer disposed functionally proximate thereto.
