Twice before in this discussion there was the assumption that the Big Carriers wanted to provide ISP services via a wireless connection…
I can assure you that they do not.
The carriers are already sun-setting their 3G technologies, despite huge investments, in lieu of 4G technologies at a rate unprecedented. The carriers are reluctant to move into 5G investments at the same rate except for one major reason. Spectral efficiency… We are at a point of spectral exhaust… Meaning we are out of capacity and the way to gain that back is via new technologies that will give us new efficiency…
The FCC is not providing a whole lot of spectrum in the future…
The point I am drawing to with the long paragraphs before this is that serving our current customer base is challenging enough… We simply couldn’t bear more traffic unless we invest in local infrastructure to do that… and we already have… its the twisted pair into your home and in some cases fiber…
Yes it wont bear the rate of 5G but to obtain that means trenching fiber into each neighborhood and street. At that point you might as well bring it straight into the home…
Perhaps the future will bear this out but for right now its not in planning…
