Abstract: A tracking device broadcasts beacon signals that are separated in time by broadcast intervals. The tracking device determines the broadcast intervals based on a behavior model. The behavior model specifies one or more conditions, such as times of day within a 24-hour day, and associates a usage probability with each condition.

This allows the behavior model to adapt to different circumstances, such as different usage patterns during weekdays, weekends, and vacations.
