Abstract

A method for data exchange with a mobile asset wherein the communication link quality at the location of the mobile asset is measured at the time of the data transfer. The packet size for the data transfer is selected in response to the communication link quality. The current communication link quality measurement may be used alone or in combination with historical communication link quality data for selecting the data packet size. Communication link quality may be determined repeatedly and the packet size reset accordingly in response to changes in the link quality. A difference between the current communication link quality and historical link quality data may trigger appropriate corrective action, such as identifying the source of intentional or unintentional jamming.
