Determining available capacity of power source for transmitter in tracing and telemetry system, based on total number data packets that can be and have been sent

摘要

The capacity is determined on the basis of the total number of data packets (11) sent by the transmitter (1) and the maximum number of data packets which can be sent using the power available. The tracing and telemetry system (10) includes at least one transmitter for sending a signal (5) such as an identification signal in the form of one or more data packets.
