All the large DOCSIS networks of which I am aware are in fact working on changing their spectrum plan and physical layer to enable higher US speeds and in some cases symmetric multi-gig services.
Yes, I’ve seen Comcast claim to offer 2G symmetric services in their applications for funding from state/local authorities to expand their networks to unserved or underserved areas. I have no reason to disbelieve this claim. I’ve been talking to vendors about what’s going on for the next generation of FTTx/PON and it looks quite attractive at this point, I’m excited to see the latency drops and speeds go up for people once they’re off DSL or DOCSIS over time. In my early days of research for my “hobby ISP” as I call it, I looked at getting older docsis systems as an option/alternative, and it seemed to be worthwhile as without a TV overlay, there were more options for speed. The reality is today once you have the infrastructure in place, if you planned well you can easily upgrade with overlays. - Jared
