Abstract

The invention relates to selecting a communication technology (34, 36) in a radio frequency (RF) based sensing system (100) having one or more nodes (26, 28, 30). The RF based sensing system (100) is configured to perform RF based sensing using one or more of two or more different communication technologies (34, 36). Based on one or more parameters related to the RF based sensing in the RF based sensing system (100), a communication technology (34) is selected for the one or more nodes (26, 28, 30) to perform RF based sensing in the RF based sensing system (100). The communication technology (36) that is optimal for a current sensing application having current sensing quality requirements in a current environment can be selected taking into account available system resources. The communication technology can be a wideband (34) and a narrowband (36) communication technology. The parameters can include sensing application parameters, sensing quality parameters, system resource parameters and environmental parameters.
