In a cell network, mr. Hog is most definately negatively impacting users on
the same radio sector and backhaul, both of which are dimensioned and
operated (like the internet as a whole) on statistical multiplexing.

If mr hog is blasting 50mbs on a 100meg link 24/7, nobody will perceive
100mbs since 50mbs is always consumed by mr hog.

Statistical multiplexing works great 99% of the time, and i personally
would rather not engineer the whole system to fight the 1% extreme users
