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).
