THE INVETOR OF THE CELL PHONE
Doctor Martin Cooper invented the modern cell phone. He invented the technology responsible for the cell phone when he was the Director of Research and Development atMotorola. Dr. Martin Cooper is also known as the first person to make a call on a cell phone. His revolutionary call took place in April of 1973 in New York. He is currently the CEO of an antennacorporation.
The Cell Phone’s Ancestors
The modern cell phone originated with Martin Cooper. However, in order to completely understand the invention of the cell phone, one has to revisit the year1947. It was then that the underlying technology that makes cell phones possible was invented. Known as hexagonal cells for mobile phone base stations, cell phones were invented through a joint effortbetween AT&T and Bell Labs. They were not actually used until the late 1950s.
Before the invention of hexagonal cells, the military (and some wealthy individuals and businesses) relied onradiophones. These phones required a large backpack device to transmit the phone’s signal to a nearby station. With the invention of hexagonal cells in the late 1940s, radiophones were rendered almostcompletely useless.
The Cell Phone’s Competitors
There was another network competing for the title of being the portable handset’s inventors. The 0G network devised a “phone for the road,” but this phonenever became a true mobile phone because it was limited to a single cell. It was not until the hexagonal cells and a feature called handover were invented in 1970 that the phone became truly mobile.People could now take mobile phones on long trips that required moving in and out of cells.
Mobile Cell Phones
Once the handover feature was implemented, it was only a matter of time before the cellphone was miniaturized sufficiently to be mobile. Yes, there were mobile phones before Martin Cooper’s invention in 1973, but they all required some sort of backpack or car-mounted unit to be used...
