It can be seen from this graph that the vast majority of
CAPEX is incurred in the BTS sites - more than 9500 of
CAPEX is directly attributable either to the coverage or the
capacity base stations. This is due to the large number of these
sites compared with the other, upper-layer network elements.
Additionally, it is shown that the coverage BTSs are sufficient
for the first four years of operation. After that, it will be
necessary to install additional sites to cope with the increasing
traffic demand. Overall, the cost of the capacity sites is
slightly higher than the cost of the coverage sites.
