Abstract: The present invention relates to adjusting one or more wireless parameters of one or more nodes (12, 14, 16) based on one or more node parameters including a relative location of the one or more of the nodes (12, 14, 16). The nodes (12, 14, 16) are wirelessly connected in a wirelessly connected system (100) and configured for transmitting radio frequency (RF) signals (18), receiving RF signals (18), or both. The one or more wireless parameters are adjusted such that the wireless performance of the one or more of the nodes (12, 14, 16) is optimized for an application of the wirelessly connected system (100). Transmission power can be adjusted such that a probability of detecting an event in a volume (212, 222) not to be covered by the one or more of the nodes (12, 14, 16) is reduced, allowing reduction of false positives from non-covered volumes (212, 222).

Abstract: The invention is related to a pair-assignment device (100) comprising a sensing-node position ascertainment unit (102) configured to ascertain position information (P.I.) pertaining to respective positions of external RF-sensing nodes (104,106) with respect to a predefined sensing volume (108) of a RF context-sensing arrangement and a pair-assigning unit (110) configured to assign, using the ascertained position information, at least one transmitter-receiver pair among the individual RF-sensing nodes of the RF context-sensing arrangement to perform a RF context-sensing function, to assign to the RF sensing nodes of the given transmitter-receiver pair a transmitter role (Tx) and a receiver role (Rx), respectively. The pair-assignment device then provides pair information indicative of the at least one assigned transmitter-receiver pair and the assigned transmitter and receiver roles and thus enables an increase of tolerance of the RF context-sensing arrangement against changes in the position of movable objects.

Abstract: An electronic device is configured to use a first protocol to transmit and/or receive a radio frequency signal during a first part (291) of each of a plurality of periods (281-285). The radio frequency signal is used for presence and/or location detection. The electronic device is further configured to obtain network messages transmitted wirelessly using a second protocol during a second part (292-294) of each of the plurality of periods. The second part does not overlap with the first part. A duration of the first part varies between at least two of the plurality of periods and/or a duration of the second part varies between at least two of the plurality of periods.

Abstract: A method for use in a lighting system for rendering emergency lighting comprises detecting (101) a switch from a normal mode of the lighting system to an emergency mode of the lighting system and a switch from the emergency mode to the normal mode and activating (103) an emergency radio frequency-based sensing function upon detecting the switch from the normal mode to the emergency mode. The radio frequency-based sensing comprises detection of disturbances to a radio frequency field. The method further comprises deactivating (105) the emergency radio frequency-based sensing function upon detecting the switch from the emergency mode to the normal mode.

Abstract: The invention is directed to a proximity-detecting device configured to determine a signal-strength value (S) indicative of a received signal power amount of an identification signal of an originating lighting node that comprises lighting-node identification information and that is received via a signal input unit (102). It also comprises a proximity-detection unit (106) configured, upon determining that the received signal-strength value exceeds a predetermined proximity threshold value (Sth), to generate and provide a proximity-information signal (P) indicative of the proximity-detecting device being within a proximity area. It also comprises a threshold-determination unit (108) configured, upon determining fulfilment of a pre-stored threshold-updating criterion (C) comprising one or more updating-conditions associated with the lighting-node identification information, to update the proximity threshold value for the given originating lighting node, for redefining the adaptation.

Abstract: A system (1) for controlling message routing within a wireless network, which comprises a plurality of nodes (1,11-15), is configured to determine a first subset of the plurality of nodes. The first subset comprises one or more devices (12,15) that are assigned a radio frequency-based presence and/or location detection function. The system is further configured to determine a plurality of routes from a source node (1) to a destination node (12). At least one of the plurality of routes comprises one or more intermediate nodes (11,13,14,15). The system is further configured to select one of the plurality of routes based on how many of the intermediate nodes of each of the plurality of routes are part of the first subset of the plurality of nodes and transmit one or more messages to cause the wireless network to perform message routing according to the selected route.
