Zusammenfassung:A communication device, method and computer program product enable reduced polling of a barometric sensor, which reduces power consumption and sensor calibration drift. A controller of a communication device determines at least one of received signal strength and direction of respective broadcast signals from local network node(s) positioned within a building to provide a local coverage area. The controller determines a location of the communication device in relation to the local network nodes in response to determining the received signal strength and/or the direction of the respective broadcast signals. The controller determines current altitude data related to a current barometer reading of the barometric sensor. The controller compares the current and the historical altitude data associated with past reading(s) at the location. In response to determining that a difference between the historical and the current altitude data is greater than a threshold distance, the controller calibrates the barometric sensor.
