We study the performance of scalable cell-free massive MIMO (CF-mMIMO) in practical urban network topologies in the cities of Frankfurt and Seoul. Our results show that the gains of CF-mMIMO - in terms of both high and uniform network throughput - are limited in practical urban topologies, compared with what is expected from theory for randomly uniformly distributed networks. We show that this is due to the locally non-uniform spatial distributions of access points characteristic of realistic network topologies, resulting in inferior throughput, especially for the worst-served users in the network.
