  This paper presents analytical expressions for the signal-to-interference
ratio (SIR) and the spectral efficiency in macrocellular networks with massive
MIMO conjugate beamforming, both with a uniform and a channel-dependent power
allocation. These expressions, which apply to very general network geometries,
are asymptotic in the strength of the shadowing. Through Monte-Carlo
simulation, we verify their accuracy for relevant network topologies and
shadowing strengths. Also, since the analysis does not include pilot
contamination, we further gauge through Monte-Carlo simulation the deviation
that this phenomenon causes with respect to our results, and hence the scope of
the analysis.
