Abstract: Method for transmitting payload data in an electric power supply connector between a power source and a wireless apparatus is disclosed. Method includes: obtaining, by the power source, payload data to be transmitted; encoding, by the power source, the payload data using a predefined voltage modulation method; altering, by the power source, a voltage level of the electric connector in order to trigger the wireless apparatus to sample the electric connector; modulating, by the power source, the voltage level of the electric connector in order to transmit the encoded payload data to the wireless apparatus; and after detecting, by the wireless apparatus, that the voltage level of the electric connector is altered, starting, by the wireless apparatus, to sample the voltage of the electric connector in order to receive the encoded payload data, and decode the encoded payload data.

Abstract: This document discloses a solution for managing a massive amount of asset tags in a system.

Abstract: Active radio-frequency identification, RFID, tag, and a product surveillance method using active RFID tags. The method includes: transmitting (202), by an active RFID tag, continuously a signal comprising an own identifier according to a predetermined schedule; receiving (204), by the active RFID tag, continuously a plurality of signals comprising a plurality of foreign identifiers transmitted by a plurality of other active RFID tags according to the predetermined schedule; measuring (206), by the active RFID tag, a received signal strength indication, RSSI, of each received signal; storing (208), by the active RFID tag, each foreign identifier of a signal whose RSSI exceeds a predetermined strength threshold; detecting (210), by the active RFID tag, that a signal with a stored foreign identifier is no more received according to the predetermined schedule and marking (212), by the active RFID tag, said stored foreign identifier.

Abstract: Relevance determination of sensor event is disclosed. An apparatus obtains a sensor event created on the basis of sensor data generated by one or more sensors, determines relevance of the sensor event, and if the relevance of the sensor event fulfills a predetermined relevance condition, outputs, with the output interface, the sensor event according to its determined relevance.

Abstract: Adjustment of sensor measurement and transmission intervals in a mobile apparatus is disclosed. The mobile apparatus obtains sensor data from the one or more sensors, and obtains wireless data with the wireless transceiver. Furthermore, the mobile apparatus adjusts repeatedly a measurement interval of the one or more sensors for obtaining the sensor data and a transmission interval of the wireless transceiver for transmitting the sensor data on the basis of the obtained sensor data and the obtained wireless data.
