It’s kinda of weird. I consider it telephony for sure (half of the TE’s I have are phones and a lot of equipment is T1/E1 equipment for PRI lines) but I also consider it under early computer data networks as it could carry X.25, Frame Relay and other types of traffic. It predates my time using computers a bit, but I believe it was also used for internet connections as uncommon as it was here.
Never got too far into X 25, I spent a couple nights after work cruising the network and finding all sorts of stuff that looked like it was on the same level of security.
people are already making their own cell networks, so not sure what's next :)
Problem same. It is not the technology it is the restriction. You use a common pool of radio which is shared. Regulation and rules of engagement abounded.
Still it is better than just radio station as ham is 2 way (and n way based on 2 way). It is a bit decentralised. But read last paragraph. Totalitarian state would not like it.)
It also may be that when I 14-18 was a transformational time for the technology of computer communication. It was exciting.
Maybe that excitement isn't there for people who are "always online".
> heh my most recent retro deep dive has been into ISDN.
Do you consider ISDN separate from telephony or part of it?
