Indoor Positioning in Wireless Local Area Networks with Online Path-Loss Parameter Estimation
Figure 9
Real world experiments: experimental setting used for data collection. The APs are marked by a red circle and indicated with , . Also the channel of the 802.11 band used by each AP is indicated. Note that we use only 3 channels in order to avoid interferences, being the distances between SS3 and SS5 and between SS1 and SS4 greater than the APs range in reception. The line in magenta represents the path used in the test and is run several times.
