Abstract
A navigation path determination system includes wireless access point devices positioned around an indoor space. While located at different indoor space locations around the indoor space, user devices transmit wireless communications with the wireless access point devices, identify wireless access point device/user device relative positioning information in respective wireless communications with each of the wireless access point devices, and transmit the relative positioning information to a navigation system. The navigation system uses the relative positioning information to determine a respective user path through the indoor space by each user device, and stores the respective user paths in a navigation path database for later use in determining a navigation path through the indoor space. The relative positioning information for each indoor space location may be unique combination of sets of wireless access point device identifiers and time-of-flight information for wireless communication transmitted by corresponding wireless access point devices.
