Innovative Database-Driven Wireless Asset Management
Improved communications coupled with smaller and less expensive GPS chipsets combine to enable today’s asset tracking applications for fleets of all sizes. These developments along with new database designs have given rise to the emerging asset management market where, in essence, billions of potentially connected assets—vehicles, trains, cargo containers, or machines coexist.
Importance of Battery-Life Monitoring and the Derived Innovations
In practical terms, asset management devices or tags must be capable of long battery life (on the order of months or years) and be rugged enough to survive the extreme environments in which they are often deployed. They must be easily integrated into a corporate IT infrastructure and this tends to use IP-based data transfer. Due to the “pay-per-bit” nature of cellular networks, transfer protocols must be optimized around packet size to ensure effective cost-based performance.
Problematic History
In the marketplace, early wireless asset management designs have been stymied by the lack of access to leading GSM and GPS chipsets, along with their embedded software stacks. This limits competitive architectures from the point of design and integration, through deployment and operation.
Until now, asset management devices have had to compromise on at least one of their key parameters, if not all three. Tags contain three fundamental building blocks: an application processor, a GPS module, and a GSM/GPRS processor. Because both the GPS and GSM modules are the major power consumers, both must be used as little as possible to conserve power resources.
An example might include the ability to access a tag in a remote facility, updating a particular parameter in software designed for a new business process. Remotely accessing the tag is critical for application efficiency and business operation. The ability to make changes to a wireless data connection in today’s fluid communications network environment can be a difficult task.
Overcoming Historic Barriers
These barriers are beginning to recede in potency as stronger ties between database designs and battery signal strength are more realistically mapped out over larger sets of case scenarios. These new devices are built to capture and report battery current strength with predictive features submitted concurrently to the application database responsible for the performance reporting of the device in question.
When tightly coupled with software, the newly introduced devices provide advanced, fully integrated low-power communications platforms with advanced database features that provide a richer data set of battery performance and thus opening the door to cost effective use of wireless asset management.
