repeated reading error noted. it says "high speed data connections", that
has nothing to do with the cable bandwidth. *that* would be, depending
on length and quality, up to several Gbs for cable. you're confusing total
capacity with the fraction that is currently reserved for _data connections_.

that is what is broadcasted, not a data connection over cable.
