Abstract: Aspects of the disclosure are related to a method for adjusting a wireless signal scanning rate based on a pedestrian dead-reckoning (PDR) reliability level estimate. An example method adjusting a wireless signal scanning rate based on a pedestrian dead-reckoning (PDR) reliability level estimate comprises estimating a PDR reliability level, determining a wireless signal scanning rate based at least in part on the estimated PDR reliability level, wherein wireless signal scanning is performed to obtain position fixes, and performing the wireless signal scanning at the determined wireless signal scanning rate.
