Sentence examples for measured path loss from inspiring English sources
Measured path loss in decibels is found to correlate well with logarithmic distance (average correlation of 0.78 over the three frequencies).
Figure 14 shows a comparison between the simulated and measured path loss values as the receiver is moved along the aisle at the height of 1.7 m.
The average correlation between path loss and logarithmic distance is 0.76. Figure 5 shows measured path loss versus distance for the three frequencies and both scenarios.
Figure 9 shows measured path loss versus transmitter-receiver distance (on a logarithmic scale) for both the signal power measurements (blue markers) and the RSSI measurements (red markers).
A first comparison between the measured path loss PLmeasured and the predicted path loss PLpredicted in the symbiotic network yielded an average prediction error δ = PLmeasured − PLpredicted of − 3.9 dB and an average absolute prediction error |δ| of 6.8 dB.
Path loss prediction data of the empirical models are compared to those of the measured path loss using first-order statistics, boxplot representations, tables, and graphs.
Source node updates table entries by measuring path losses between the source and the relay nodes.
We also measured the path loss at different distances with three different frequencies.
Table 5 summarizes for all trajectories on the third floor (T1-T5, A-H, and corr) the measured average path loss PLms [dB], the predicted path loss PLpr, and the deviation δ [dB] = PLpr - PLms for the considered model for Tx and Rx at heights of 2.5 m and 1 m, respectively.
Table 5 shows for all trajectories on the second floor (used for modeling) the measured average path loss PLms [dB], the predicted path loss PLpr, and the deviation δ [dB] for the considered model for Tx and Rx at heights of 2.5 m and 1 m, respectively.
Datasets containing measured and predicted path loss values are presented in a spreadsheet file, which is attached to this data article as supplementary material.
