As a result, optimizing the BTS cost structure is crucial to
the SAE network operator. One way to do this is to use as low
a frequency for the coverage BTS network as possible. For the
capacity sites, the operator should strive to gain as much
capacity bandwidth per carrier as possible. It should be
remembered that the actual number of sites drives a number of
base station related costs. Additionally, the reuse of existing
cellular sites for SAE equipment could be highly significant in
optimizing costs. Finally, the operator should also carefully
consider which market areas to target, taking into account
both the size of the potential market and the corresponding
land area.
The total operating expenses are shown below in Figure 3.
