Without evangelicals and dreamers major new ISP infrastructure wouldn't get built. But it has to run into practical realities of what a network will look at all the way down the OSI model stack. People want gigabit FTTH to every home in the USA but the construction costs could be $5,000 per house on average.
I followed this closely and thank you for pointing out the cost implications per house connection. While that's a significant amount in the USA,it's far monstrous in the developing countries/rural areas;which from this forum are touted as the major targets of the SpaceX system. Do you see a way of reducing this cost that can practically serve a rural town in, for example, Africa? (I'm from East Africa and trying to make sense of what this new development means for local ISPs)
If you have a town/city of population 2,500 to 20,000 that has very poor internet connectivity in general at present, this will probably be most useful in its larger version to bring one relatively high capacity DIA/IP link (like 150 Mbps downstream x 50 Mbps upstream) to a single central location, as an ISP POP in the town, and then local distribution throughout a US county-sized area by point-to-point and point-to-multipoint terrestrial microwave in the 2.4, 3.5, 3.65, 5.2 and 5.8 GHz bands. Possibly with some use of low-cost equipment in the traditional licensed (6, 11, 18, 23) GHz bands, unlicensed 24 GHz band PTP, 60 and 80 GHz, etc.
Much appreciation for this feedback. I definitely need to dig further, but your comments are painting quite a discernable image of what the system means from an end user POV. We still got almost 5 years to its realization but something worth keeping tabs on.
