WINNER D5.4 v. 1.4<br />
In 2005 a new series of measurements was performed at two locati<strong>on</strong>s, Oulu University main building<br />
<strong>and</strong> Oulu University wing building Tietotalo. Two different buildings were measured at 5.25 GHz with<br />
100 MHz b<strong>and</strong>width. In the two buildings, more than 8 BSs were chosen with many different routes.<br />
Tietotalo is a typical office envir<strong>on</strong>ment, the corridors of which are narrow with widths around 1.8<br />
meters. In the university main building, the corridors have different width, the widest is around 3.5<br />
meters. In the room measurements at the university main building, the room size is very close to 10 m by<br />
10 m, as in the definiti<strong>on</strong> of the scenario A1. In Tietotalo the sizes of the measured rooms were<br />
comparable to 10 m by 10 m. The largest combined sets of IRs for deriving <strong>channel</strong> <strong>models</strong> <strong>and</strong><br />
parameters are over 55000.<br />
The indoor envir<strong>on</strong>ments here are divided into the following 4 cases:<br />
(1) Corridor-corridor LOS (c-c LOS): both BS <strong>and</strong> MS were placed at the corridors.<br />
(2) Room-corridor <strong>and</strong> corridor-room NLOS (r-c NLOS): BS in a room, MS in an adjacent corridor<br />
vice versa.<br />
(3) Room-room LOS/OLOS (r-r LOS/OLOS): both BS <strong>and</strong> MS in the rooms.<br />
(4) Corridor-corridor NLOS (c-c NLOS)<br />
In the analysis, 100 IRs for a drop are used (about 1.4 meters), if no window length is menti<strong>on</strong>ed.<br />
The following definiti<strong>on</strong>s are used: paths = peaks = ZDSC, Noise cut <strong>level</strong>s used in the analysis: For<br />
LOS: 28 ~ 35 dB. For NLOS: 15 dB ~ 30 dB.<br />
5.2.2 Scenario B1<br />
5.2.2.1 HUT background campaign<br />
These measurements were performed outside the WINNER project by HUT <strong>and</strong> they were used as<br />
background data for Scenario B1. The sounder was the HUT sounder with centre-frequency 5.3 GHz <strong>and</strong><br />
b<strong>and</strong>width (chip rate) 60 MHz. The measurements in the micro-cell envir<strong>on</strong>ment included both LOS <strong>and</strong><br />
NLOS routes in a fairly regular rectangle street grid with 4-5-storey buildings. In the measurements the<br />
fixed Tx antenna was a 16-element dual-polarised planar patch antenna array <strong>and</strong> the mobile Rx antenna a<br />
semispherical antenna with 15 dual-polarized patch elements. The antennas are shown in Figure 5.9.<br />
5.2.3 Scenario B3<br />
5.2.3.1 TUI campaign<br />
These measurements were d<strong>on</strong>e with the RUSK ATM MIMO sounder by Medav [Medav]. The centrefrequency<br />
in the measurements was 5.2 GHz <strong>and</strong> the b<strong>and</strong>width was 120 MHz. The indoor envir<strong>on</strong>ment<br />
c<strong>on</strong>sisted of a university lecture hall (c<strong>on</strong>ference hall) <strong>and</strong> the entrance area (foyer) next to it. The foyer is<br />
characterized by a 2 floor open envir<strong>on</strong>ment, with dimensi<strong>on</strong> of 15m x 30m x 8m. The c<strong>on</strong>ference hall is<br />
a typical lecture hall envir<strong>on</strong>ment with slowly elevated sitting rows; the dimensi<strong>on</strong> is 30m x 35m x 15m.<br />
In all measurement cases the Tx was moving <strong>on</strong> the same track, whereby the positi<strong>on</strong> of the Rx was<br />
changed in the hall. Within the c<strong>on</strong>ference hall scenario two different main setups where used, namely<br />
LOS <strong>and</strong> NLOS/OLOS, where in the latter the LOS was obstructed by an absorber mat.<br />
The pictures of high-resoluti<strong>on</strong> antennas used in TUI measurement campaign are shown in Figure 5.7.<br />
