Element planning Route expansion Route augmentation System integration Figure 4.47 Utilizing the operator processes for evaluating alternative solutions, such as vertical versus horizontal Understanding Changing Telecommunications - Building a Successful Telecom Business Overall Result of the Cost Comparison: Cost of Ownership for the Network Core Cost of ownership combines CAPEX and OPEX (Figure 4.48). According to Figure 4.46, the new architecture and the old one has approximately the same CAPEX, whereas OPEX differs significantly. However, other sources claim a significantly lower CAPEX for the new architecture as well. From Figure 4.48 the conclusion cannot be drawn that CAPEX is not decisive, since this is just an example. Anyway, the large impact of the next generation on OPEX is clear. In addition, the operator need for agility and flexibility is strongly supported. 4.7.2 RESULTS OF PARTICULAR COMPARISONS Traffic Planning Let us start with the planning area. Traffic planning becomes much easier with the new network. Compare the route reduction in Figure 4.49. Going from many networks to one or a few simplifies the work, saving resources and time.
