We Could Have Had Cellphones Four Decades Earlier (reason.com)
_Sharp'r_ writes: Professor Thomas Hazlett of Clemson University analyzed the history of wireless spectrum and concluded the technology was known and available for cellphones in the 40s, but there was no spectrum available. Based on assumptions cellphones would always be luxury goods without mass appeal, significant spectrum for divisible cellular networks wasn't legally usable until the early 80s. Instead, the unused spectrum was reserved for the future expansion of broadcast TV to channels 70-83. Here's an excerpt from the report: "When AT&T wanted to start developing cellular in 1947, the FCC rejected the idea, believing that spectrum could be best used by other services that were not 'in the nature of convenience or luxury.' This view -- that this would be a niche service for a tiny user base -- persisted well into the 1980s. 'Land mobile,' the generic category that covered cellular, was far down on the FCC's list of priorities. In 1949, it was assigned just 4.7 percent of the spectrum in the relevant range. Broadcast TV was allotted 59.2 percent, and government uses got one-quarter."
Yes car phones.

Domestic spying is now "Benign Information Gathering"
...and so were cellular telephones when they first came to market. All that you needed was a scanner.
It was so easy to listen to any cell phone conversation, that website operators even setup websites allowing anyone to listen to live cell phone conversation streams in various cities.

Let's make like a bird... and get the flock outta here.
Cell phones used analog transmissions as late as 2008. How do I know this? Because that was when my cell provider bought me a new phone so they could retire all their analog equipment. I had a "dual mode" phone then that could do digital and analog. The FCC would not allow the cell providers to get rid of their analog equipment until enough of their subscribers had digital phones. I hung on to that phone so long that not only did I get a free phone but I was paid $50 to take the free phone.
Another thing that prompted the switch were instances of high up government officials having their phone calls listened to by people with scanners.

NO
It was the transistor which meant a radio transmitter could be smaller than 2 cubic feet, and cost less than a Harley-Davidson bike.
Evidently, some people were born yesterday (or clickbait).

Transistors were invented in the late 1940s. Mobile phones did not become common until the 1980s with the adoption of cellular tech. RTFA.
