I wonder how someone could claim to invent the cell phone, ever watch the Beverly Hillbillies the banker on the car phone and recall now this show was made in the 1960s, it was the same tech Amateur Radio, Ham Radio I know for a fact has used the same tech for 35 years or more, only it is called using a phone patch I was using those 20 years ago.Tone pad check,radio tower on hills and mountains check,handheld radio check,I think he may have invented cell phones at the same time al gore invented the internet.
The difference is the way the network operates; the cell phone network decides when to hand you off to a new cell based upon the signal strength of your phone and the load of a given cell. That’s what makes it a cell phone; it will make and break connections to different radio towers - cells - based upon what the network decides is best for your communications.
He invented the hand-held cell phone while at Motorola. The radiophone in cars already existed.
