Abstract

See full text

A system for providing local barometric calibration for user equipment is disclosed. In particular, the system may utilize an over-the-air signal to feed local barometric pressure measurements to the user equipment so as to auto-calibrate the barometric sensor of the user equipment to the local barometric pressure. The local barometric pressure may be collated to the serving cell site identifier or wireless access point to which the user equipment is connected. The local barometric pressure measurements may be obtained by the optimal resource available in the area associated with the user equipment. For example, the local barometric pressure measurements may be obtained from the Internet, a local weather service, a local serving beacon, or other source. The barometric sensor may be calibrated at desired intervals, when certain conditions are satisfied, or any combination thereof.
