DOCSIS 3.1 uses channel bandwidths of up to 192 MHz in the downstream. [15] Upstream: DOCSIS 1.0/1.1 specifies channel widths between 200 kHz and 3.2 MHz. DOCSIS 2.0 & 3.0 specify 6.4 MHz, but can use the earlier, narrower channel widths for backward compatibility. DOCSIS 3.1 uses channel bandwidths of up to 96 MHz in the upstream. Modulation:

If this is a de facto standard imposed by modem chipset manufacturers, ISPs, et al, this article should say so. Separately but related. That 42.88 Mbps rate per channel for 256-QAM is obtained by multiplying 8 bits per symbol times the symbol rate 5.360537 Msym/s stated in DOCSIS 3.0 PHY spec. (pg 100). 8 x 5.360537 == 42.884296 Mbps
