2 Figure 3.6 Example of propagation model tuning application.

3 Figure 3.8 Cell loading (Colours indicate the actual loading value in a certain threshold range).

4 Figure 3.16 The selected network scenario. Average site distance being roughly 910 m.

5 Figure 3.17 The link losses for the macro-cellular operator. An additional loss of 12 db has been introduced for locations inside buildings.

6 Figure 3.19 Number of connections in the network area. Main outage areas are inside buildings.

7 Figure 3.25 Example of network scenario for the six sectored base stations in the Shinjuku case.

8 Figure 3.27 Example for the needed DL link power for the macro-operator's network. Visible are also some dead zones, where the maximum link power is not sufficient for good enough QoS.

9 Figure 3.28 Used network scenarios in urban case.

19 Figure 3.48 Served users, uplink loadings and downlink transmissions powers for a network where a macro-carrier is reused in all micro-cells. The black line across the right-hand figure denotes the minimum power level required for pilot and other common channels. The network was initially loaded with 4340 users i.e., 140 users per micro-sector. The service probability in this case was 93%.

20 Figure 3.49 Downlink dominance areas based on highest received pilot power for f1 micro-cells in an HCS network.

21 Figure 3.50 Downlink f2 dominance areas for f2 micro- and macro-cells, when macro-carrier f2 is reused on the micro-layer. Circulated cells are examples of microcells, which can establish clear dominance areas and collect traffic under the overlying macro-layer. The pilot power difference between micro- and macro-cells in 6 db. Dominance areas of, for example, micro-cells 7 and 12 (shown with arrows) have shrunk considerably compared to Figure 3.49.
