This dataset presents real measurements of radio frequency signals in a railway corridor within the Atlantic Forest in the state of São Paulo, Brazil. A transmitter antenna fixed on a pole inside the corridor was used together with an RF generator transmitting a CW signal in the 460 MHz band. A mobile receiving antenna was installed on the roof of a locomotive and connected to a spectrum analyzer, a laptop and software for data reading were used together, coupled to a GPS antenna. Thus, the measured signal was geographically recorded as the train traveled along the corridor.

A wide range of wearable sensors exist on the market for continuous physiological health monitoring. The type and scope of health data that can be gathered is a function of the sensor modality. Blumio presents a dataset of synchronized data from a reference blood pressure device along with several wearable sensor types: PPG, applanation tonometry, and the Blumio millimeter-wave radar. Data collection was conducted under set protocol with subjects seated at rest. 115 study subjects were included (age range 20-67 years), resulting in over 19 hours of data acquired.
