On April 3, 1973, standing on Sixth Avenue in New York City near the New York Hilton hotel, Martin Cooper made a phone call from a prototype Dyna-Tac handheld cellular phone before going to a press conference upstairs in the hotel. The phone connected Cooper with the base station on the roof of the Burlington House across the street from the hotel and into the AT&T land-line telephone system.
This first phone weighed about 2.5 lb (1.1 kg). It was the product of Cooper's vision for personal wireless handheld telephone communications.
