So in Poland with Starlink I easily get 120 mbp/s but often in Kenya which I visit the maximum speed is just 10 mbp/s. Often the local 5g network is faster. The reason I believe that this is the case is dues to congestion on the Starlink network in Kenya. Ie. too many users in Kenya.
I suspect that has a lot to do with still needing a ground station in the same hex as the signal. Presumably, there's limited bandwidth at wherever that ground station is.
Once the satellites are linked, I bet that improves.
For what it's worth, I was specifically thinking about DSL and 2000-2010s era DOCSIS technologies. The analogy is really that when mobile phones became popular in Africa, it was possible to skip the step of having wired landlines and cable TV. 3G/4G could be used for anything those would have provided. Starlink does the same thing, but it lets people skip DSL and cable modems.
However, I actually think that the main "benefit" you get by not having an extensive wired infrastructure is the lack of an incumbent provider. Centralized incumbents can put pressure on any new technology that puts their existing infrastructure investments at risk.
Fiber requires custom engineering at the city block level and a single rotten utility pole can block deployment.
I say this as someone who waited for fiber and is happily using it now.
