Where is FWA Finding Customers?

Where are cellular carriers finding the millions of customers they are adding to fixed-wireless access (FWA) cellular broadband? In urban areas, the customers would have to be coming from cable companies, telephone company DSL, or fiber. In rural areas, customers would be coming from DSL, satellite, or cellular hot spots. I’ve been doing some digging, but my research is far from scientific. I’ve looked in detail at half a dozen counties using detailed Ookla speed tests to see where the FWA customers live. I noticed in this tiny sample that there are a lot more FWA speed tests in rural areas than in towns. There are FWA customers in cities and dense suburbs, but the relative penetration of FWA in densely populated areas looks to be relatively miniscule. I still have no idea of the extent to which cable companies are losing customers to FWA or fiber. They are certainly losing to both – but the cable companies and their competitors are staying mum on the topic.
