The
phone in a short amount of time has had a major impact on information and communication technology development around the globe. But the technology has been around quite some time. Remember,
Cellular phones are basically transmitters and Radio signals.
The Cellular phones came about through a lot of work by different folks like James Maxwell (the math behind
Electromagnetic Waves), Heinrich Hertz (that neat unit of frequency and the means for creating and detecting electromagnetic waves), and Guglielmo Marconi (using electromagnetic
Waves in wireless communication).
Dr. Martin Cooper, is widely credited as the "
Father of the Cellphone." in 1973, Dr. Cooper was a project manager for Motorola. On April 3 of that year, he and his team set up a cellular base station with a small antena box on the roof of what is now the Alliance Capital Building in New York City, and from outside Manhattan Hilton, he placed what is considered the first handheld cellular call, to Joel Engel, the chief researcher at Bell Laboratories. The phone used was the Dyna-Tac phone. This was a unit that weighed 2.5pounds, measured 9x5x1.75 inches, and after a charging period of 10hours, allowed a user to dial or receive or talk on a phone conversation for 35mins.
Dr. Henry Thomas Sampson, was a doctor of engineering form University Of Illinois, USA. Between 1956 and 1961, Sampson worked on a number of projects that ultimmately led to numerous patents. Most noteworthy, is the july 6, 1971
patent (#3,591,860) held by both Sampson and Professor George Hunter Miley, also of the Universiti Of Illinios for something called "Gamma Electric Cell." This was a
power source of high-voltage, low-current applications that could also be used to detect radiation, and without leaking significant amounts of power, unlike previous designs. Its nuclear how and to what degree the model of their device detected FM radio wave, but it is, without much doubt, a patent which is cited as crucial to the ultimate design of the cellphones we know today.
