The elements of 5G networks are irregularly placed and thus best modeled and analyzed using tools from stochastic geometry. The SIR distribution at the typical user, which permits a first-order performance analysis, only describes the average performance of all links or users and thus does not reveal how concentrated the per-user SIR levels are. To capture the disparity between users, a more refined metric is needed, the so-called meta distribution of the SIR.
The meta distribution is based on a clean separation of time and spatial scales and answers questions such as “what fraction of users achieve an SIR of 5 dB with 95% reliability?”. 
In this talk, we discuss recent advances on the meta distribution for 5G networks. We also present the distribution of the downlink ergodic spectral efficiency over the users.
