The first 1G network launched in the USA was Chicago-based Ameritech in 1983 using the Motorola DynaTAC mobile phone.
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.
