In the Brazilian Higher Education context, Federal does not mean collegiate (even though most Federal Universities in Brazil enjoy a similarly collegiate system), but it means that the institution is funded by the Union (who is the fiscal-juridical person that embodies the Federation, in the context of the Federative Republic of Brazil), which implies they are necessarily free of charge for all.
