Summary: This paper investigates the uplink (UL) performance of cell-free massive multiple-input multiple-output (CF mMIMO) systems supported by mmWave-fronthaul networks. Analytical expressions for the distribution of the provided fronthaul capacity and the average UL data rates are derived using stochastic geometry. The results show that increasing the density of blockages degrades the average UL data rates, but increasing the density of central processing units (CPUs) can limit this effect. The study also reveals that the network deployment should be adjusted based on the available fronthaul bandwidth and the density of blockages. Increasing the density of access points (APs) beyond a certain limit does not achieve further improvement in the UL data rates. Furthermore, increasing the number of antennas per AP may even cause a degradation in the system performance.
