Not sure if this is what you're referring to with your reference to "aether
... replaced by coax", but... Ethernet's channel access algorithm (CSMA-CD) is
slightly different from Aloha's (which was, IIRC, CSMA). (To get the -CD to
work semi-reliably they had to limit the network's physical size, and increase
the minimum packet size, in ways that weren't feasible with the aether.) I
seem to recall that adding the -CD upped the theoretical throughput (as a
%-age of channel bit rate) considerably.
