These speed numbers are low compared to 1–2 Gbit/s upload speeds stated on Wikipedia page for DOCSIS. They have to use 4096 QAM?

The 1-2 Gbps is if it's 4k QAM across 204Mhz upstream RF bandwidth.

Currently they top out around 40 MHz RF bandwidth and maybe 14 MHz of 256 QAM or 512 QAM, mixed with 3 channels of 64 QAM
