摘要： The invention is directed to a water-detection device (100) for detecting a change in an amount of water (W) with respect to a baseline-condition. The water-detection device is configured to compare signal-quality values to baseline-values. The signal-quality values are indicative of a signal-quality metric that is correlated to the amount of water present in a signal-propagation path (S). The baseline-values are indicative of the signal- quality value obtained from the radio-frequency wireless communication signal at the baseline-condition. The water-detection device is configured to provide a water-detected signal (WD) indicative of a possible change of the amount water in the respective signal- propagation path upon determining that respective signal-quality value has been outside a tolerance-range of the baseline-value for a predetermined amount span, without the need of any dedicated water sensor.

摘要： The present invention relates to operating an RF system (100) comprising multiple nodes (26, 28, 30) for transmitting and/or receiving RF messages (34). RF messages transmitted by a transmitting node (26) are received at receiving nodes (28, 30). It is determined whether the RF messages were completely received. Upon missing at least part of the RF messages at the receiving nodes, it is determined whether missing of at least part of the RF messages is caused by an activity event of a tangible entity (32) in transmission paths (40) between the transmitting node and the receiving nodes based on one or more RF system criteria. The RF messages (34) may include RF-based sensing messages (36) and RF data messages (38). A discrepancy between missed parts of the RF-based sensing messages and missed parts of the RF data messages may be determined and included in the RF system criteria.

摘要： The present invention relates to RF-based sensing in an RF system (100) comprising multiple nodes (10,..., 20) at different locations. At least two of the multiple nodes (12, 14) form a first group (28) of nodes that performs RF-based sensing in a first sensing area (30) for detecting a first sensing event. A second sensing event detection performance for performing RF-based sensing in the first sensing area (30) for detecting the first sensing event by the first group together with an additional node (20) or by the first group with one of the nodes (14) of the first group removed from the first group is determined. The second sensing event detection performance can be compared to a first sensing event detection performance for performing RF-based sensing by the first group (28). Based on the comparison it may be decided whether to add or remove a respective node (20, 14).
