Figure 5.12. Indoor path loss in corridor – corridor LOS c<strong>on</strong>diti<strong>on</strong>s.<br />
The equati<strong>on</strong> for the path loss can now be expressed as<br />
PL(d) = 46.8 + 18.7 log 10 (d), s = 3.1 dB ( 5.2)<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. The equati<strong>on</strong> is valid from 1<br />
m to 200 m.<br />
Very similar results were obtained in the previous measurement campaign [D5.3] for LOS c<strong>on</strong>diti<strong>on</strong>s, but<br />
for limited range. Other similar results, with the path-loss exp<strong>on</strong>ent less than 2, have been discussed in<br />
several references cited in Secti<strong>on</strong> 5.5.<br />

5.4.1.1.2 Measurements in room - corridor NLOS c<strong>on</strong>diti<strong>on</strong>s<br />
The path-loss curve for the 5.25 GHz centre-frequency in room – corridor (corridor – room) LOS<br />
propagati<strong>on</strong> c<strong>on</strong>diti<strong>on</strong>s can be seen in Figure 5.14. The measurements were performed so that either the<br />
BS was in the corridor <strong>and</strong> the MS in the room al<strong>on</strong>g the corridor or vice versa. The wooden doors from<br />
the corridor to the rooms were closed. It was measured that the attenuati<strong>on</strong> of the door was 4 dB.<br />
