A healthcare system is provided with RF sensor modules that can be integrated into various components and subsystems or that can be retrofit. Sensors modules include a sensor adapted to detect operational data. The modules may process and store the data, and perform aggregation functions to simplify or reduce the data. The data is then collected from the modules by an RF transceiver and conveyed to downstream processing layers. The processing layers may evaluate the operation of the components or subsystems, or the overall health or functioning of the component, subsystem, or any other useful subdivision of the healthcare system.
