"In 1984, Bell Labs developed modern commercial cellular technology (based, to a large extent, on the Gladden, Parelman Patent), which employed multiple, centrally controlled base stations (cell sites), each providing service to a small area (a cell). Frenkiel, the head of system development at Bell Laboratories, said about the DynaTAC: 'It was a real triumph a great breakthrough' " (Wikipedia article on Motorola DynaTAC, accessed 03-16-2013). The call, made at Soldier Field in Chicago, is considered by many as a major turning point in communications. "On October 13, 1983, David D Meilahn placed the first commercial wireless call on a DynaTAC from his 1983 Mercedes 380SL to Bob Barnett, former president of Ameritech Mobile Communications, who then placed a call on a DynaTAC from inside a Chrysler convertible to the grandson of Alexander Graham Bell who was in Germany for the event. DynaTAC was an abbreviation of Dynamic Adaptive Total Area Coverage." It offered 30 minutes of talk time and 8 hours of standby, and a LED display for dialling or recall of one of 30 phone numbers. "The first model, the 8000x, received FCC certification in 1983, and became the first cell phone to be offered commercially when it went on sale on 6 March 1983. It was also the first portable cell phone small enough to be easily carried. In October 1983 the Motorola DynaTAC 8000x became the first mobile phone approved by the FCC in the United States.
