Abstract
Examples of techniques for constructing a spatial map of a physical space are disclosed. In one example implementation according to aspects of the present disclosure, a computer-implemented method includes collecting, by a processing device, signal strength data about a plurality of user devices as the plurality of user devices move throughout the physical space, the signal strength data being indicative of a signal strength of a wireless signal between at least one of the plurality of user devices and at least one of a plurality of access points associated with the physical space. The method further includes generating, by the processing device, a signal space map based at least in part on the signal strength data. The method further includes transforming, by the processing device, the signal space map of the physical space into the spatial map of the physical space to construct the spatial map of the physical space.
