History of mobile phones
A cellular telephone switching plan was described by Fluhr and Nussbaum in 1973, and a cellular telephone data signaling system was described in 1977 by Hachenburg et al.
George Sweigert
Sweigert predicted that half of the people in the world would own a wireless phone in the time of his children. With the current world population of wireless phones at 3.2 Billion in 2008, he was probably not far wrong with this prediction. He predicted integrated cameras, GPS, accelerometers, and other advanced sensors in the 1969 moon lander would be integrated into the wireless phone. Sweigert received notice of his patent approval the same day of the first moon landing on June 20, 1969.
