First Invention of Mobile phone
In December 1947, D. H. Ring, a Bell Labs engineer, proposed hexagonal cells for mobile phones. Phil Porter, also of Bell Labs, proposed that the cell towers be at the corners of the hexagons rather than the centers and have directional antennas that would transmit/receive in 3 directions. The technology did not exist then and the frequencies had not yet been allocated. Cellular technology was undeveloped until the 1960s, when Richard Frenkiel and Joel Engel of Bell Labs developed the electronics.
After Some Inventions
Dr. Martin Cooper of Motorola, with the DynaTAC 8000X, first unveiled in 1983. Dr. Cooper made the first analogue mobile phone call on a larger prototype model in 1973.
