The increasing demand for location-aware services inside buildings has made indoor positioning a significant research topic. While the outdoor location can be easily calculated, using technologies such as GPS. The location using fingerprinting technique is consist of two different phases: the first phase is the calibration phase at specific points called calibration points within the environment, the signal strength at each point is recorded and saved in a database; the second phase is the location estimation phase where the object measures the signal strength at its current position and then, using a location estimation algorithm, the measured signal is estimated with values stored in the database in order to obtain an approximation on the user's current position.
