fact about the cell phone
Cooper and his team at Motorola, the communications company, created maybe the only thing that runs the lives of business professionals and teenagers alike -- the cell phone.
It was the size of a brick and wasn't commercially sold for another decade. But as Cooper demonstrated on a New York sidewalk, it worked.
The concept of cellular technology had already been created by Motorola's rival, AT&T, whose Bell Labs introduced a system allowing calls to be moved from one cell to another while remaining on the same channel. But AT&T was focusing this technology on the car phone.
Cooper wanted people to have freedom to talk on the phone away from their cars. So in reaction, he and Motorola embarked on a project to create a more portable device.
Motorola spent three months building a prototype for a portable, mobile handset that Cooper publicly demonstrated in April of 1973. The company's first commercial cellular phone, the "DynaTAC," went on sale 10 years later.
The idea of a cell phone began in the 1930's, but the first protype was done by Bell Labs in 1947. Dr. Martin Cooper of Motorola is given credit for the cell phone in 1974. It was not until 1984 cell phones were sold to the public.
Mobile payments were trialed in 1998 in Finland and Sweden where a mobile phone was used to pay for a Coca Cola vending machine and car parking. Commercial launches followed in 1999 in Norway. The first commercial payment system to mimic banks and credit cards was launched in the Philippines in 1999 simultaneously by mobile operators Globe and Smart.
