| Indoor positioning systems based on 802.11
and fingerprints offer reasonably low position errors. We study
the key factors for position errors by systematically
investigating (1) the number of access points, (2) the number of
samples in the training phase, (3) the number of samples in the
position determination phase, and (4) the setup of the grid of
reference points. Further, we squeeze out the best of the
positioning system by selecting advantageous values for these
parameters. For our study, we utilize a test environment with a
size of about 312 square meters that is covered with 612
reference points arranged in an equally spaced grid. |
