Title: 1345 Avenue of the Americas
Content:  A base station atop the building was used on April 3, 1973, by Martin Cooper to make the world's first handheld cellular phone call in public. Cooper, a Motorola inventor, called rival Joel S. Engel of Bell Labs to tell him about the invention. Engel was staying across the street in the Hilton New York.

Title: Bell Mobility
Content:  The first cell phone conversation in Canada took place on the Bell network between Jean Drapeau and Art Eggleton, the mayors of Montreal and Toronto, on July 1, 1985. The first cell phone customer in Canada was Victor Surerus, a travelling funeral director out of Peterborough, Ontario who purchased a $2,700 CAD telephone set and took out a service subscription with Bell Canada in July 1985. Bell Mobility discontinued its Advanced Mobile Phone System (AMPS) analog mobile network in February 2008.

The development of metal-oxide-semiconductor (MOS) large-scale integration (LSI) technology, information theory and cellular networking led to the development of affordable mobile communications. The first call on a handheld mobile phone was made on April 3, 1973 by Martin Cooper, then of Motorola to his opposite number in Bell Labs who were also racing to be first. Bell Labs went on to install the first trial cellular network in Chicago in 1978. This trial system was licensed by

Title: Advanced Mobile Phone System
Content:  in Chicago, Illinois, in 1979. Motorola and others designed and built the cellular phones for this and other cellular systems. Martin Cooper, a former general manager for the systems division at Motorola, led a team that produced the first cellular handset in 1973 and made the first phone call from it. In 1983 Motorola introduced the DynaTAC 8000x, the first commercially available cellular phone small enough to be easily carried. He later introduced the so-called Bag Phone. In 1992, the first smartphone, called IBM Simon, used AMPS. Frank Canova led its design at IBM and it was demonstrated that year at the COMDEX computer-industry trade-show. A refined version of the product was marketed to consumers in 1994 by BellSouth under the name Simon Personal Communicator. The Simon was the first device that can be properly referred to as a "smartphone", even though that term was not yet coined.
Title: Digital media
Content:  Motorola named Martin Cooper was the first person to make a phone call on April 3, 1973. He decided the first phone call should be to a rival telecommunications company saying "I'm speaking via a mobile phone". However the first commercial mobile phone was released in 1983 by Motorola. In the early 1990s Nokia came into succession, with their Nokia 1011 being the first mass-produced mobile phone. The Nokia Communicator 9000 became the first smartphone as it was inputed with an Intel 24 MHz CPU and had 8 MB of RAM. Smartphone users have increased by a lot over the years
