  The meta distribution (MD) of the signal-to-interference ratio (SIR) provides
fine-grained reliability performance in wireless networks modeled by point
processes. In particular, for an ergodic point process, the SIR MD yields the
distribution of the per-link reliability for a target SIR. Here we reveal that
the SIR MD has a second important application, which is rate control.
Specifically, we calculate the distribution of the SIR threshold (equivalently,
the distribution of the transmission rate) that guarantees each link a target
reliability and show its connection to the distribution of the per-link
reliability. This connection also permits an approximate calculation of the SIR
MD when only partial (local) information about the underlying point process is
available.
