WINNER D5.4 v. 1.4<br />
Figure 5.18: Shadow Fading distributi<strong>on</strong> in LOS (a) <strong>and</strong> NLOS (b) envir<strong>on</strong>ment.<br />
5.4.1.4 Scenario C1<br />
5.4.1.4.1 Measurements in LOS c<strong>on</strong>diti<strong>on</strong>s<br />
The path loss is shown in the figure below for the centre-frequency 5.25 GHz in LOS propagati<strong>on</strong><br />
c<strong>on</strong>diti<strong>on</strong>s. The measurements have been c<strong>on</strong>ducted in a 100 MHz b<strong>and</strong>width.<br />
Figure 5.19: Path-loss in a suburban envir<strong>on</strong>ment <strong>and</strong> LOS propagati<strong>on</strong> c<strong>on</strong>diti<strong>on</strong>s.<br />
Path-loss formula is<br />
PL(d) = 41.6 + 23.8 log 10 (d), s = 4 dB. (5.7)<br />
where d is the distance <strong>and</strong> s is the st<strong>and</strong>ard deviati<strong>on</strong> of the shadow fading.<br />
The equati<strong>on</strong> is valid from 25 m to the break-point value, see Secti<strong>on</strong> 5.6.1. From 1 m to 25 m, free-space<br />
loss formula should be used.<br />
5.4.1.5 Scenario D1<br />
5.4.1.5.1 Measurements in LOS c<strong>on</strong>diti<strong>on</strong>s<br />
In the D1 rural LOS scenario the measurements were c<strong>on</strong>ducted both in the year 2004 [D5.3] <strong>and</strong> in the<br />
year 2005. In the campaign of the year 2005, the LOS measurement was c<strong>on</strong>ducted in slightly different<br />
routes than in the previous year. Measurements were performed for three different BS locati<strong>on</strong>s, each<br />
having several measurement routes. The results are shown in the Figure 5.20.<br />
