Figure 5.79: The auto correlati<strong>on</strong> functi<strong>on</strong>s obtained from (*) using the λ parameters of Table 3.4<br />

<strong>and</strong> the single exp<strong>on</strong>ential functi<strong>on</strong>s obtained from measurements from Scenario D1 NLOS.<br />

5.5 Literature review<br />

5.5.1 Scenario A1<br />

5.5.1.1 Path-loss<br />

In [WHL94], the indoor measurements were performed using network analyzer at 2 <strong>and</strong> 5 <strong>and</strong> 17 GHz,<br />

the RF b<strong>and</strong>width was 500 MHz. The envir<strong>on</strong>ment of the measurement locati<strong>on</strong>s was composed of a<br />

corridor of length 21.7 m, width 2 m <strong>and</strong> height 3 m <strong>and</strong> a room with dimensi<strong>on</strong>s 7 x 8 x 2.8 m. Both<br />

antennas were mounted <strong>on</strong> st<strong>and</strong>s at a height of 1.8 m.<br />

It was found that in LOS cases, the path-loss exp<strong>on</strong>ents are 1.5, 1.7, <strong>and</strong> 1.6 respectively at the three<br />

frequency b<strong>and</strong>s. There is almost no difference <strong>and</strong> <strong>on</strong>e cannot find how the path-loss exp<strong>on</strong>ents change<br />

with frequencies. However, for OLOS cases, the path-loss exp<strong>on</strong>ents were increased with the centrefrequencies.<br />

In [SG00], the measurements were performed at 5.2 GHz (RF BW was not clear) <strong>and</strong> mainly investigated<br />

the path-loss <strong>models</strong> for indoor envir<strong>on</strong>ments including the same floor corridor-corridor (LOS), corridorroom<br />

(NLOS), <strong>and</strong> room-room (NLOS) measurements <strong>and</strong> also different floor path-loss measurements.<br />

Antenna type: two patch antennas or two dipole antennas were applied.<br />

2. Cross floor measurement results:<br />

Horiz<strong>on</strong>tally polarized antennas:<br />

Case 1: The transmitter Tx was located at the 6th floor, then the receiver Rx was moving in a corridor at<br />

5th floor.<br />

Case 2: The Tx was at 6th floor, <strong>and</strong> the Rx was moving in vertical line between floors 0 <strong>and</strong> 5.<br />
