Not to hijack the thread, but just to put things in perspective, the mobile phone dates back to 1946. It was originally intended to keep The President, and other top people, in comm in any city they went to. All of the larger cities had operating commercial systems by 1965. The main highways between cities were covered by 1975. The systems were big and costly (both to buy and to use) and had low capacity, but they were there.
It got to be so congested that the cellular arrangement came into being in 1983 as a way to handle the ever increasing number of users. The original system used lower frequency bands with long range, so the cities could be covered by one radio site. There was one in NYC on the Empire State building and had a 100 mile range. Only 30 channels, though, so think about that: In 1975, all of NYC could be covered by one base, but only have 30 mobile phone calls at one time!
Of course, most work-a-day journalists probably didn't have one in their cars, but their bosses did.
I still have a couple stacks of ex-mobile telephone radios on the shelf. At one time, they were prime sources of surplus radios to convert to service in the ham bands.
This, of course, is the same old story of technology. Whatever the popular gadget is today, is a *lot* older then anyone thinks it is!
Just like the QV vs. the appliance digicam of today. A lot older than most people think!
