2.1.4.2 Scenario B5b: LOS stationary feeder: street-level to street-level
Our understanding of this case in indicated in Figure 2.3. Both ends of the link are located a few meters
above ground and the model is aimed for 2-5 meter antenna heights. In many cases it may be possible to
place the antennas high enough such that the first Fresnel zone is clear and therefore free-space
propagation conditions apply.

2.1.5 Scenario C1: Suburban macro-cell
The scenario C1 is defined for a suburban outdoor environment, where the coverage is ubiquitous. In
suburban macrocells base stations are located well above the rooftops to allow wide area coverage.
Buildings are typically low residential detached houses with one or two floors, or blocks of flats with a
few floors. Occasional open areas such as parks or playgrouds between the houses make the environment
rather open. Streets have random orientations, and no urban-like regular strict grid structure is observed.
Vegetation is modest.
2.1.6 Scenario C2: Urban macro-cell
In typical urban macrocell, mobile station is at street level and fixed base station clearly above
surrounding building heights. As for propagation conditions, non- or obstructed line-of-sight is a common
case, since street level is often reached by a single diffraction over the rooftop. The building blocks can
form either a regular Manhattan type of grid, or have more irregular locations. Typical building heights in
urban environments are over four storeys. Outdoor-to-indoor modelling is not part of typical urban
macrocell scenario, but is a different scenario (Table 2.1, C4).
