So car phones were not mobile? As in they were in an autoMOBILE? Question unclear. Remember i am an old guy. I've seen things more than 40 years old. So I get to question them.

Actually, it goes further back than that. Amateur radio (Hams) originated the technology in the 60's. NOT CB! The methodology is called dual band FM in which the transmit function is done on one band and the receive is done on another. This allows "full duplex" communication in which simultaneous talk and listening occur. The other part of the technology is called Autopatch and Repeaters. One can be in a vehicle with a radio and connect with a repeater station (cell tower), which then uses Autopatch (radio to landline) to connect to the telephone network. dialing is done via a DTMF (dual tone multi frequency) encoder/decoder, which generates the tones necessary to trigger tone dialing, which also began in the 60's. Complete the picture with the use of a handheld radio and you have the first truly mobile telephone. Hams built repeaters everywhere, so as long as you were within range of one, and it has Autopatch enabled, you could make a phone call.

Motorola also produced dual band radios using FM for the Amateur radio community. The peripheral technology I described was INVENTED by Amateur radio hobbyists though.

, CB's operate on the 11 MHz band using AM. So no, nothing like CB radio. At all.
