System and method for managing remotely and distantly located assets

#1. Technical Field of the Invention

#The principles of the present invention are generally directed to an asset management system, and, more specifically, but not by way of limitation, to a system and method using a wireless architecture to communicate with wireless devices associated with the assets.

#Asset management and tracking has become an important issue for large and small companies due to financial considerations, customer concerns, and governmental regulations, for example. Technology in the fields of information technology (IT) and telecommunications has evolved to enable robust wireless communications to perform asset management, especially in a variety of aspects that solve business problems that do not necessarily require instantaneous or active communication between a central computer and an asset (i.e., mobile or fixed). As even the most stable communications networks tend to fail, depending on the particular asset management application, failure of the communications network may severely disrupt business operations. Additionally, communications networks may be bandwidth and/or cost prohibitive for many asset management applications.

#The principles of the present invention provide for a robust wireless communications system that performs asset management of mobile and/or fixed assets. The robust wireless communications system accounts for network failures and throughput issues by providing intelligence in both the wireless infrastructure and mobile wireless devices (e.g., asset communicators) associated with the assets. By including intelligence in the wireless infrastructure and asset communicators, the assets may remain substantially operational even in the event of a communication link failure between the central computer and the wireless infrastructure and/or between the wireless infrastructure and the asset communicator(s). Additionally, an asset that becomes out-of-range of the wireless infrastructure may still perform intended duties and utilize the associated asset communicator to perform the asset management functions. Furthermore, by incorporating intelligence into the wireless infrastructure and asset communicators, business decisions can be made that are simply not possible without such intelligent devices, often without transmitting any data.

#The robust wireless communications system is capable of distributing downlink data utilized in performing the asset management functionality in a sequential, but not necessarily simultaneous, transmission from the central computing system to the wireless infrastructure and from the wireless infrastructure to the asset communicators. In that regard, and in contrast to traditional wireless communications systems, the asset communicators need not have active links between (i) the central computing system and wireless infrastructure, and (ii) the wireless infrastructure and asset communicators for the data to be downloaded to the asset communicators. Accordingly, the data may be transmitted to the asset communicators by the wireless infrastructure irrespective of the communication link between the central computing system and wireless infrastructure. In the uplink direction, the asset communicators are able to receive data from the asset and/or generate data without an active communication link with either the wireless infrastructure and/or the central computer. Upon the communication link between the asset communicator and wireless infrastructure becoming established, the data may be uploaded to the wireless infrastructure, stored therein, and further uploaded from the wireless infrastructure to the central computing system upon a connection being established thereto.
