Abstract: A gateway device for associating the gateway device and tracking sensors as single a cargo unit: the gateway device being associable with a cargo unit, said gateway device comprising: means to detect position or movement, and short-range wireless communication means for sending out a beacon signal and connecting with nodes, characterized in that the gateway device is arranged to detect which nodes are still in short-range communications range when change of position or movement is detected and associating the nodes that are still in range with as being part of the same cargo unit as the gateway device. Corresponding arrangement and method are also presented.

Abstract: An arrangement for sensor node calibration, including a calibration chamber including or being connected to a unit to facilitate control of at least one calibration quantity or attribute in the calibration chamber, a reference measuring unit arranged to measure at least one calibration quantity or attribute inside the calibration chamber, and a computing unit arranged to obtain from at least one sensor node sensor node identifier (ID) information, sensor node measurement information, wherein the computing unit is arranged to identify a sensor node based on sensor node ID information received from the sensor node, obtain measurement information the identified 0sensor node, obtain calibration quantity or attribute measurement in-formation from the reference measuring unit, and compare calibration quantity or attribute measurement information with sensor node measurement information. Corresponding device and method are also disclosed.

Abstract: An arrangement suitable for a mobile local wireless network includes: a gateway to facilitate a local short-range wireless network, to receive at least sensor measurement data via the short-range wireless network, and to be connected to an in-situ computing device; a computing device connected to the gateway, having a unit to obtain sensor measurement data via the gateway from sensor nodes; a sensor node transmitting measurement data via long-range wireless networks, and transmitting measurement data and receiving beacon signals via short-range communication. The gateway sends beacon signals. The sensor node receives a beacon signal and utilizes only the short-range wireless network for sending the measurement data, terminating transmission of data over long-range wireless networks for a period of time, in accordance with commands received from the gateway or as long as a beacon signal is detected at the sensor nodes. Corresponding gateway, method and computer-program product are also disclosed.

Corresponding arrangement and method are also presented.

Abstract: A gateway device for controlling sensor network transmission frequency comprising: means to detect the gateway device location, transmission means arranged to at least transmit a beacon signal in the UHF band, characterized in that the gateway device is arranged to detect radio frequency band limitations associable with the detected location, and further sending beacon signal on 868/915 MHz frequency, or on 2.4 GHz frequency or other available ISM/SRD frequency if frequency band limitations associable with the gateway location are detected. Corresponding arrangement and method are also presented.

Abstract: A gateway device for a sensor network comprising: communication means to communicate with an aircraft interface device or other communication means provided by aircraft, short-range wireless communication means for communicating with nodes via short range communication means, characterized in that the gateway device is arranged to receive flight status information from the aircraft interface device and to facilitate control of nodes in accordance with the flight status, such as that the gateway sends the nodes a command to disable all wireless transmission when the aircraft status is take off or landing, and a command to utilize only short-range wireless transmission means when the aircraft status is climb, cruise or descent. Corresponding arrangement and method are also presented.
