Abstract:

A wireless communication device capable of determining its location in an indoor environment is disclosed. In an indoor environment, a wireless communication device may have insufficient access to GNSS satellites or cellular towers to make an accurate determination as to its location. Therefore, the wireless communication device generates a fingerprint map of the environment by estimating its position and scanning multiple positions within the environment for accessible access points and characteristics. The device stores this information in memory, which it can later refer to for determining its current position.
