Abstract
A method for fingerprinting positioning decision support includes obtaining a geographic distribution probability of positions of measurement. A first collection of simulated measurements according to a signal model is generated, wherein each simulated measurement is associated with a respective pixel. The signal model is based on base stations located in the area. Fingerprinting positioning reference data is computed from the first collection and positions of the selected pixels. A second collection of simulated measurements is generated, which is statistically independent to the first collection. These simulated measurements are associated with a respective intended position within the area. Fingerprinting positioning is performed by the second collection utilizing the computed fingerprinting positioning reference data. An estimated accuracy of the fingerprinting positioning is calculated using a comparison between the intended position and the estimated position. This is made to evaluate positioning capabilities of fingerprinting positioning based on the measurement strategy.
