It might shock one to learn that the basic technology behind cellular radio was invented by Bell Labs (AT&T/Ma Bell) in 60's & successfully field-tested in Chicago in 1970. After that, the FCC sat on it for 15 years! There was a predate "carphone" service, (MTS/IMTS), but it was limited in capacity & range.
