I admittedly know little about the service from the radio out in FWA deployments like this but have done a lot of work in the aggregation and backhaul arenas in both environments. The advantage the FWA folks have is that it is significantly more financially viable to not oversubscribe (or oversubscribe less) when you deliver more users from a more centralized next hop location. In other words, it’s easier and cheaper to have 100 Gbps serving 1000 users from a single location than it is to have 1 Gbps serving 10 users from 100 different locations. Which is not to say that there aren’t other challenges in FWA environments relative to FTTx environments, but system capacity (you can always add more radios, with enough available spectrum, at least) isn’t one of them.
