Abstract
Aspects of the present disclosure relate generally to generating reliable data for indoor navigation. More specifically, aspects relate to identifying a route for a person to follow in order to record data such wireless network access location or other beacon signal information and signal strengths for an indoor space. In one example, the pre-defined route may be generated based on a map of the indoor space, a set of predefined walking strategies, an average walking speed, a time limit, and an optimization goal. For example, if a person is able walk at some average speed for a set period of time, a route may be identified which provides a given density of data points (the optimization goal) within the indoor space. The collected data may then used to build a wireless network model of the indoor space for navigation.
