Train The Trainers
One of my pet peeves is when a trainer trys to explain the "history of wireless" and manages to totally garble things. Now, I'm not the type to stop a class and go into a long-winded dispute. That's just wrong. But I do know that the trainer who blew me off lurks here, so here's a non-technical answer.
When I mentioned that there were mobile phones prior to "analog" he mumbled "you mean the police cars" and walked away. Sadly, the "radio cars" of the 1920's were NOT a commercial service available to the public. For that we had to wait until the 1940's (MTS). That system must have been a joy, all-tube equipment, live operator, one-way talking, and three calls per system. The second system (IMTS), which came out in the 1960's, was much better, transistors, real two-way conversations, you dial the number, and over twenty calls in a service area.
In the 1980's the microprocessor made "cellular" service available. You still had a hard time getting more than twenty calls in a service are, but now the service area was only a couple miles across. Which meant that you could have hundreds of calls in the area that the older systems could only do twenty. And that's why "analog" is called 1G, because it is the first generation of cellular. Everything else that's come out after analog has increased the number of calls you could have in an "area". There's more stuff, but I'm already pushing the topic so here I'll stop.

But the real question is why is this relevent info and if so what is it relevent to?????

That was in the post, if people can rant over sups I can rant over trainers. Sorry to confuse you, but at least this was about phones, remembering some of the other posts we've read here.
