Tracking systems and methods for remotely tracking a location of a person on a map of a monitored premise

This invention describes a system for tracking people's locations inside buildings. Each person carries a mobile device that detects nearby wireless network access points, like Wi-Fi routers, which are at known locations. The device then sends this information to a central system, which can share the person's location with others. The first claim specifically describes how the mobile device itself can help set up and edit the map of the building by showing available access points and their signal strengths.
