摘要： The present invention relates to performing RF-based sensing and reacting to an event detected by the RF-based sensing with a consistent latency or at least with a latency within a latency range around the consistent latency. A latency of two or more groups (30, 40, 50, 60) of nodes (34, 36, 38, 44, 46, 54, 56, 64, 65, 66, 67, 68) each for performing RF-based sensing and reacting to the event detected by the RF-based sensing in a respective sensing area (32, 42, 52, 62) of multiple sensing areas is determined. The consistent latency is determined based on the determined latencies. At least one of the two or more of the groups (50, 60) is adapted such that they perform RF-based sensing and react to the event detected by the RF-based sensing with the consistent latency or at least with a latency within a latency range around the consistent latency.

摘要： The invention is directed to a signal-emission control device (100) for controlling emission of RF communication signals (Si) in a wireless communication network (140) that includes a transmitter device (152) and a receiver device (154). The emission is controllable with respect to a variable signal parameter (P). An emission-value ascertainment unit (102) is configured to ascertain variation-data indicative of an emission-value variation of signal-parameter values of the signal parameter. A scheduling unit (110) is configured to ascertain operation-trigger data indicative of operation conditions for triggering control of emission of the wireless RF communication signals in accordance with the ascertained emission-value. A transmitter-control unit (104) is configured to control operation of transmitter device for transmitting the communication signals (Si) according to the emission-value variation of the respective signal-parameter value upon fulfilment of the operation conditions. This enables an increase of the verisimilitude of the provided communication signals against illegitimate RF-based eavesdropping.

摘要： The present invention relates to an RF system (100) with a first node (10) and an RF signal diffuser (40). The first node (10) is configured for transmitting an RF signal (30). The RF signal diffuser (40) is configured for reflecting the RF signal (30) in multiple directions in order to generate additional paths (38) for a multipath channel based on the RF signal (30). The RF signal diffuser (40) and the first node (10) are arranged with a distance (50) to each other and are configured such that at least one of the additional paths (38) of the multipath channel has sufficient transmission power for performing RF-based sensing in asensing area (60). The RF system (100) is configured for performing RF-based sensing based on at least two paths (36, 38) of the multipath channel including at least the one of the additional paths (38).

摘要： The present invention refers to an apparatus (130) that allows for the controlling of an adding of a third party device (121) to a sensing group (110)) to improve the sensing. The sensing group consists of network devices (111, 112, 113) performing radiofrequency sensing. The third party device provides a functionality that contributes to the sensing of the sensing group. The apparatus comprises a determination unit (131) for determining a critical sensing functionality, a determination unit (132) for determining a potential contribution that the functionality of the third party device can provide to the radiofrequency sensing, when the third party device is added to the sensing group, and a controlling unit (133) for controlling the adding of the third party device to the sensing group based on the critical sensing functionality and the potential contribution.

摘要： The invention refers to a system for controlling a radiofrequency sensing of a network 100. The network is adapted to perform different radiofrequency sensing modes, e.g. RSSI-, CSSI- or Doppler based modes. The system 130 comprises a providing unit 131 for providing environmental information, wherein the environmental information is indicative of a physical property of one or more surfaces in an environment of the network. A selecting unit 132 is adapted for selecting and/or modifying a radiofrequency sensing mode to be performed by the network, wherein the radiofrequency sensing mode is selected and/or modified based on the environmental information, and a controlling unit 133 is adapted for controlling the network 100 to perform the selected and/or modified sensing mode Taking the physical properties of surfaces in an environment into account and modifying and/or selecting the utilized radiofrequency sensing mode accordingly increases the reliability and the accuracy of the radiofrequency sensing.

A fall-event detection unit (108) is configured to determine, based on a time variation of the subject-activity data of at least one subject-activity metric, whether a fall-event has occurred. A fall-event type classification unit (110) is configured, using a predetermined algorithm and subject-activity data of at least two subject-activity metrics determined during a first time span before and a second time span after the determination of the fall-event, to determine a fall type, from a predetermined list of fall types, with increased accuracy.
