Abstract :
The infeasible signal-to-interference ratio (SIR) region is a set of SIRs that are not supportable in a power-controlled wireless network. It was conjectured that this set is convex in networks constrained on total power. We disprove the conjecture and discuss how this result may impact optimal medium-access control policies
