In this research project, it was investigated in which framework a basic supply with 10 Mbps on the one hand and a gigabit supply with 1 Gbps on the other hand can be realized via FWA from an economic point of view, depending on the density of the settlement. In order to enable a radio-based supply with the target data transmission rates to be considered here, the use of appropriate carrier frequencies and bandwidths is required. We compare the associated investments in FWA connections with investments that have to be made for FTTH coverage.
The comparison is based on a simplified, model-based approach for mapping different population densities resp. building distance and thus supply requirements. In practice, each individual constellation for the use of FWA will have to be evaluated. Generally valid statements do not seem possible, since in practical implementation the environmental influences not considered here (topology, vegetation, buildings, possibility for aerial cabling, existing masts, number of users in the radio cell, possibility of line of sight, etc.) always have a relevant influence on the performance of a radio-based solution and must be taken into account.
