Considering all the costs of the mobile use case, the total
CAPEX for the Western European country is a little above 51
million Euros over the ten-year period. This translates to about
3.6 Euros per user. (The total customer base rises to
approximately 14.2 million during the study period.) The total
CAPEX is thus quite similar to that of the fixed case, with an
increase of just 5000, despite the tenfold increase in the
customer base. As long as the data rates per user remain low,
the SAE network can therefore cover very economically
greatly increasing numbers of users.
