9.1.1 Scenario definitions
Here we present WP5 view to the environments beyond the five prioritized scenarios.
9.1.1.1 Scenario “high mobility short range hot spot”
This scenario is new and therefore not described in [D7.2]. We call it “High Mobility Short Range Hot
Spot”. It represents an outdoor hot spot application for short range distances, where the distance can be
range from few meters to 250m. The Rx can be fixed e.g. on the side or even under a bridge. The Tx is
mounted on the roof of a car, van or lorry. Within this scenario high mobility and traffic throughput with
high density can be expected. Such scenarios can be found in rural, urban and suburban environments,
e.g. for traffic information or other user applications. Depending on the environment different MIMO
channel characteristics must be considered.
Technische Universität Ilmenau (TUI) measured this particular scenario “High Mobility Short Range Hot
Spot”, where the measurement car (Tx) was driving on a highway and the Rx was fixed at a bridge in a
rural environment. No buildings were in this area only high trees and shrubs surrounding the highway and
bridge. Both LOS and NLOS propagation situations can be expected. Mostly LOS is obvious when the
car is approaching the bridge, under and after the bridge NLOS is dominating.
9.1.1.2 Scenario “outdoor to indoor”
See [ZJ05].
9.2 Measurement campaigns for other scenarios
9.2.1 Scenario “high mobility short range hot spot”
9.2.1.1 TUI campaign
TUI outdoor high mobility short range hot spot measurement scenario consists of a bridge-to-car scenario
in a highway, shown in Figure 9.1. These measurements were done with RUSK ATM MIMO sounder by
Medav [Medav]. The Carrier frequency in the measurements was 5.2 GHz and bandwidth of 120 MHz.
During the measurement campaign the Tx was driving on the right and left side lane of a two lane
highway road (2 lanes per direction). The Tx antenna was mounted on the roof of a car and the Rx as
mounted at the bridge, whereby it was down tilt by 45 degrees. Pictures of high-resolution antennas used
in TUI measurement campaign are shown in Figure 5.7. The maximum distance between Tx and Rx
antenna position was found to be 250m, which defines the short range area for the hot spot application.
