Ethernet Doomed?
>From SIRBU@Mit-Mc Thu Mar 11 08:07:59 1982
I'm sorry, but Ethernet does not reguire a MODEM, it requires a
TRANSCEIVER.  There's a big difference.  A modem implies RF oscillators
and receivers with lots of filters and other non-digital components.
Transceivers, operating on honest-to-goodness digital signals, not
RF tones, are easier to build.

The controllers, on the other hand, which packetize and do the right
thing when collisions are detected, are essentially the same for
baseband and broadband CSMA-CD networks.
