Conclusion
Interruption of the communications is the
precursor to war Phantom Menace, a Star Wars
movie
A prescription for a peaceful coexistence in
communication standards Do not affect my
throughput by more than 10. Or I will jam you
and you will therefore suffer a throughput loss
as well. And in this game, lack of coexistence
means that there are no winnersonly losers.
