Abstract: A wireless device includes first and second transceivers for wireless communication and is operable to switch between first and second states, with the second state at least partly prohibiting communication by the first transceiver. The wireless device is configured to perform a control method which involves sharing of state data among wireless devices. According to the method, the wireless device receives, by the second transceiver, a state indicator and confidence data from one or more other wireless devices. The state indicator indicates a current state of the respective other wireless device, and the confidence data is indicative of a confidence of the current state. The control method sets the wireless device in the first or second state based on the state indicator and the confidence data.

Abstract: An electronic device is configured to, during transportation to a destination, determine its position and transmit position data to a remote computer. To lower power consumption and enable arrival detection based on the position, the electronic device obtains, based on a first position determined at a first time point, an estimated remaining transportation time to the destination, and determines, based on the estimated remaining transportation time, a second time point for determining a second position. The electronic device may then determine the second position at the second time point. Alternatively, to account for unscheduled delays, the electronic device may determine a third time point by selectively modifying the second time point based on sensor data from a movement sensing system on the electronic device and determine the second position at the third time point.
