  13. 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 winners…only losers. Art Astrin, Apple Computer Inc.
