Abstract
The description relates to receiver gain offset. One example can obtain data sensed by a mobile device at a position. The example can evaluate the sensed data and survey data to identify a venue proximate to the position. The survey data of the venue can be organized into regions and then individual regions can be organized into sub-regions. The example can compare signal strengths of the sensed data to signal strengths of the survey data to identify the position relative to an individual region. The comparison can utilize a receiver gain offset estimation between the mobile device and another device that acquired the survey data. The example can refine the receiver gain offset estimation and attempt to identify the position relative to an individual sub-region within the individual region utilizing the refined receiver gain offset estimation.
