Final report on link level and system level channel models - Winner

WINNER D5.4 v. 1.4
5.2.4 Scenario C1
5.2.4.1 EBIT campaign
Measurements were conducted during 2004 for the suburban scenario C1 at the centre-frequency 5.25
GHz. Measurements by Elektrobit were performed in Heinäpää relatively near to Oulu centre in an area,
where the houses are lower than in the centre of the town, with some parking lots, parks and trees along
the streets in between the houses. The height of the houses varied typically from 3 to 6 stories. Due to the
measurement routes mainly LOS conditions were encountered. It should be noted that this environment
was clearly different from the environment, where Nokia performed their measurements for C1 scenario.
5.2.4.2 NOK and HUT campaign
Measurements were done using the NRC/RAD/EDM radio channel sounder (Elektrobit PropSound). The
centre-frequency used in the measurements was 5.3 GHz, and the chip rate was 100 MHz. The
measurement campaign was targeted to support the following WINNER channel model development
purposes:
• Creation of a path-loss model
• MIMO performance evaluation
• Doppler spectra characterization
• Direction-of-departure (DoD) and direction-of-arrival (DoA) analysis
Altogether three base station sites (some of them with two sectors) were measured in two different types
of suburban environments in Helsinki, Finland. The first environment was a residential area occupied
mostly with low, one or two floor single family or terraced houses with occasional open areas, such as
playgrounds or gardens, in between. The second environment was rather loosely built residential area
with higher 3-4 floor high apartment buildings. Open areas, play grounds and small forest sections were
in between the apartment buildings, as well as occasional lower 1-2 floor buildings.
A truck-operated crane was used to lift up the transmitter. The receiving antenna (user mockup) was
located on top of the van, and the receiver sounder unit was inside the van. In this case several continuous
routes of lengths 50…800 meters each were measured. For DoA/DoD measurements the spherical array
and the sounder receiver unit were set to a battery-powered trolley to allow slow enough moving speeds.
Due to huge amounts of data in this case shorter routes of 10-20 meters were measured in dozens of
different locations within the sector. Some antennas used in Nokia and HUT campaign are shown in
Figure 5.8.

5.2.5 Scenario C2
5.2.5.1 KTH measurements
A measurement campaign was conducted in the Vasastan area of Stockholm city. The area can be
characterized as a typical European urban with mostly six to eight stories high stone buildings and
occasional higher buildings and church towers. The measurements were done in uplink direction with a
mobile-station transmitting four separate CWs on four separate antennas with a frequency separation of
