Figure 2.1: Layout of the A1 indoor scenario.
The measured environment resembles this definition, but is not identical [WP5AR]. It is assumed that
propagation parameters can be deduced from these measurements.
2.1.2 Scenario B1: Urban micro-cell
This scenario is defined for environment where both fixed station and mobile station antenna heights are
below surrounding buildings and both are outdoors. This scenario covers both LOS and NLOS
propagation conditions. The environment is defined for Manhattan like grid. The environment streets can
be classified as a main street, where the fixed station is located, perpendicular streets and parallel streets.
The scenario is defined for street distance from 20 m to 400 m. In this environment, the radio propagation
and cell shape are confined within the area defined by the surrounding buildings.
2.1.3 Scenario B3: Indoor hotspot
The scenario B3 is described in [D7.2] and represents a typical indoor hot spot application with a wide
coverage area but non-ubiquitous and low mobility (0-5 km/h). In this scenario traffic of high density can
be expected. Typically application scenarios can be found in conference halls, factory halls, entrance halls
of train stations and airports, where the indoor environment is characterised by large distances. The
dimensions of such large halls can range from 20 m x 20 m x 5 m up to more then 100 m in width and
length as well as 20 m in height. Both LOS and NLOS propagation situations can be found in this
scenario.
2.1.4 Scenario B5: Stationary feeder
The definition of this scenario is less well understood by WP5 than are the others. WP5 found that that
NLOS cases are also of interest for the feeder applications. We therefore discuss models for NLOS cases
as well. The following different feeder scenarios have been studied:
• B5a Hotspot LOS stationary feeder: rooftop-to-rooftop
• B5b Hotspot LOS stationary feeder: street-level-to-street-level.
• B5c Hotspot LOS stationary feeder: blow-rooftop-to-street-level
• B5d Hotspot NLOS stationary feeder: above-rooftop-to-street-level.
The scenarios of B5a and B5b are discussed below:
2.1.4.1 Scenario B5a: LOS stationary feeder: rooftop-to-rooftop
Our understanding of this case is illustrated in Figure 2.2. Wireless feeder master-station, probably on an
elevated building, is connected to one or several wireless feeder peripheral stations. A hot-spot wireless
access point is then connected to the peripheral. As indicated in the picture, a cable is needed to connect
the roof-top wireless feeder peripheral antenna. Alternatively a wireless solution may be possible also for
these hops but then requiring additional antennas and transceivers.
